Tinnitus: workup and management

Clinical Overview and When to Suspect Tinnitus

— ~10–15% of US adults report chronic tinnitus; ~20% of these find it bothersome

— Peak prevalence age 60–69; men > women; veterans and noise-exposed workers disproportionately affected

— Leading service-connected disability in US veterans

— Primary (idiopathic): with or without sensorineural hearing loss, no identifiable cause

— Secondary: linked to a specific cause (cerumen impaction, otosclerosis, Ménière, vestibular schwannoma, ototoxic drug, TMJ, vascular lesion)

— Recent (<6 months) vs persistent (≥6 months); bothersome vs non-bothersome drives management intensity

— Subjective (only patient hears) vs objective (examiner can auscultate — vascular or myoclonic origin)

— Unilateral tinnitus → rule out retrocochlear lesion (vestibular schwannoma)

— Pulsatile tinnitus → vascular cause (dural AV fistula, carotid stenosis, venous sinus stenosis, glomus tumor, idiopathic intracranial hypertension)

— Tinnitus + focal neuro deficit, sudden hearing loss, or vertigo → urgent workup

Definition: Perception of sound without external acoustic stimulus — ringing, buzzing, hissing, clicking, or pulsing in one or both ears

Epidemiology:

Classification (AAO-HNS 2014, reaffirmed):

When to suspect a dangerous etiology:

Primary care role: Most tinnitus is managed longitudinally in the outpatient setting; specialty referral is selective

Step 3 management: For a patient with bilateral, symmetric, non-pulsatile tinnitus and gradual hearing loss, the highest-yield first step is a targeted history, otoscopy, and audiogram — not MRI. Reserve imaging for asymmetric, pulsatile, or neurologically concerning presentations.

Board pearl: Sudden sensorineural hearing loss accompanied by tinnitus is a medical urgency — start oral corticosteroids within 2 weeks and obtain audiogram + MRI; do not dismiss as "ear wax" or anxiety.

Presentation Patterns and Key History

— Onset: sudden vs gradual; trauma, barotrauma, loud noise exposure, new medication, URI

— Laterality: unilateral (concerning) vs bilateral (usually benign)

— Duration: acute (<3 months), subacute, chronic (≥6 months)

— Character: ringing/hissing (sensorineural), low-pitched roar (Ménière), pulsatile (vascular), clicking (palatal/middle ear myoclonus)

— Associated: hearing loss, vertigo, aural fullness, otalgia, otorrhea, headache, visual changes

— Relieving/aggravating: noise environment, posture, jaw movement, caffeine, stress

— Severity & impact: sleep, concentration, mood — use Tinnitus Handicap Inventory (THI) or Tinnitus Functional Index (TFI)

— Noise exposure: occupational (construction, military, music), recreational (firearms, concerts)

— Ototoxic meds: aminoglycosides, loop diuretics (high-dose IV furosemide), cisplatin, salicylates (high-dose, reversible), NSAIDs, quinine, vancomycin, macrolides

— Comorbidities: HTN, atherosclerosis, DM, thyroid disease, depression/anxiety, TMJ dysfunction

— Psychiatric screen: depression and anxiety strongly co-travel with bothersome tinnitus and worsen perceived loudness — screen with PHQ-9 and GAD-7

— Sleep: insomnia common; addressing it improves tinnitus distress

— Unilateral + asymmetric hearing loss → acoustic neuroma

— Sudden onset over hours → SSNHL, urgent ENT

— Tinnitus + neuro deficits → CNS workup

— Suicidal ideation related to tinnitus → mental health emergency

Core symptom characterization (mnemonic: OLD CARTS applied to tinnitus):

Targeted history domains:

Key distinction: Pulsatile tinnitus synchronous with heartbeat = vascular workup pathway (carotid bruit, MR/CTA, consider IIH if obese woman of reproductive age with headache and papilledema). Non-pulsatile, bilateral = audiologic pathway.

Red flags from history alone:

Board pearl: Always ask about firearms use in middle-aged men presenting with high-frequency hearing loss and tinnitus — recreational shooting without hearing protection is the most common missed exposure.

Physical Exam Findings (and Hemodynamic Assessment when relevant)

— Cerumen impaction — reversible cause; remove before further workup

— TM perforation, retraction, effusion, cholesteatoma (white keratin debris in pars flaccida)

— Red mass behind TM → glomus tympanicum/jugulare (pulsatile tinnitus)

— Schwartze sign (reddish promontory blush) → otosclerosis

— Weber: lateralizes to affected ear in conductive loss; to unaffected ear in sensorineural loss

— Rinne: AC > BC normal; BC > AC suggests conductive loss ≥25 dB

— Whispered voice test as quick screen; formal audiogram still required

— Bell of stethoscope over periauricular area, mastoid, neck, orbit, skull

— Audible bruit → carotid stenosis, dural AV fistula, venous hum

— Synchronous with pulse → arterial; non-pulsatile rhythmic clicking → palatal or stapedial myoclonus

— Bilateral BP, carotid auscultation, cardiac murmurs (AS radiates to neck and mimics carotid bruit)

— Fundoscopy for papilledema (IIH workup)

— BMI; IIH classically in obese women of reproductive age

— Palpate TMJ during opening; crepitus or tenderness → TMJ-related somatosensory tinnitus

— Modulation of tinnitus with jaw clench, neck rotation, or pressure on muscles = somatosensory tinnitus (often responsive to physical therapy)

Otoscopy (highest-yield single maneuver):

Hearing assessment in office:

Auscultation for objective tinnitus:

Cranial nerve exam: CN V, VII, VIII especially — facial weakness or trigeminal numbness with unilateral tinnitus = CPA lesion until proven otherwise

Vestibular testing: Dix-Hallpike, head impulse test, gait/Romberg if vertigo accompanies tinnitus

Cardiovascular & hemodynamic exam (especially pulsatile tinnitus):

TMJ and cervical exam:

CCS pearl: On a CCS case of pulsatile tinnitus in a young obese woman with headache, order fundoscopy and visual acuity early — papilledema mandates urgent neuro-ophthalmology referral and LP; missing IIH risks permanent vision loss.

Board pearl: Tinnitus that changes pitch or intensity with neck or jaw movement is somatosensory in origin and rarely needs imaging.

Diagnostic Workup — Initial Labs / Imaging / ECG / Biomarkers

— Pure-tone audiometry (air and bone conduction, 250–8000 Hz, with high frequencies 9–16 kHz if available)

— Speech audiometry (speech reception threshold, word recognition score)

— Tympanometry (middle ear status, eustachian tube function)

— Acoustic reflexes (helps localize lesion site)

— Otoacoustic emissions if outer hair cell function in question

— High-frequency notch at 4 kHz → noise-induced

— Sloping high-frequency loss → presbycusis

— Low-frequency sensorineural loss → Ménière disease (early)

— Carhart notch at 2 kHz → otosclerosis

— Asymmetric SNHL → MRI internal auditory canals

— TSH if other thyroid signs or unexplained fatigue

— CBC if pulsatile tinnitus suggests anemia/hyperdynamic state

— Lipid panel, HbA1c, BP as part of cardiovascular risk modification (associated with tinnitus severity)

— Syphilis serology (RPR/FTA-ABS) if otosyphilis suspected (fluctuating SNHL, immunocompromised)

— ANA, ESR/CRP if autoimmune inner ear disease suspected (rapidly progressive bilateral SNHL)

— MRI brain with IAC protocol, with gadolinium for asymmetric SNHL, unilateral tinnitus, neuro deficits → rule out vestibular schwannoma

— CTA or MRA head/neck for pulsatile tinnitus → dural AV fistula, carotid stenosis, venous sinus stenosis

— CT temporal bone if pulsatile + middle-ear mass (glomus tumor) or suspected dehiscence

Audiometry is the cornerstone — order in essentially all chronic tinnitus patients:

Audiogram patterns clue etiology:

Labs — not routine, but targeted:

Imaging — guided by red flags, not routine:

ECG: if pulsatile tinnitus with palpitations, or to evaluate for AF causing turbulent flow

Key distinction: AAO-HNS guidelines recommend against routine imaging for bilateral symmetric non-pulsatile tinnitus with symmetric hearing loss — high cost, low yield, incidentalomas cause harm.

Board pearl: The single most important initial test in chronic tinnitus is the audiogram — it stratifies risk, identifies treatable hearing loss, and determines candidacy for amplification (which itself treats tinnitus).

Diagnostic Workup — Advanced or Confirmatory Studies

— Indicated for: unilateral tinnitus, asymmetric SNHL (≥15 dB difference at 2 contiguous frequencies, or per local audiology criteria), pulsatile tinnitus with negative CTA, sudden SNHL, focal neuro signs

— Detects vestibular schwannoma, meningioma, epidermoid, MS plaques in brainstem, small infarcts

— Order without and with contrast, thin cuts through IAC and CPA

— First-line for pulsatile tinnitus

— Evaluates carotid stenosis, fibromuscular dysplasia, dural AV fistula, aberrant carotid, persistent stapedial artery

— Suspected venous sinus stenosis or dural sinus thrombosis (transverse/sigmoid sinus)

— Often paired with workup for idiopathic intracranial hypertension

— Suspected superior semicircular canal dehiscence (Tullio phenomenon — tinnitus/vertigo triggered by loud sounds; autophony)

— Otosclerosis, glomus tumor bony erosion, cholesteatoma

— Gold standard if dural AV fistula suspected and non-invasive imaging non-diagnostic; can be both diagnostic and therapeutic (embolization)

— If IIH suspected (obese reproductive-age woman, pulsatile tinnitus, headaches, papilledema, normal imaging) — opening pressure >25 cm H₂O

— VNG, vHIT, VEMP if Ménière, vestibular migraine, or CPA lesion suspected

— Electrocochleography (ECochG) — elevated SP/AP ratio supports Ménière disease

— Pitch matching, loudness matching, minimum masking level — useful for sound therapy fitting, not diagnosis

MRI brain with internal auditory canal (IAC) protocol + gadolinium:

CT angiography head/neck or MR angiography:

MR venography:

CT temporal bone (high-resolution, no contrast):

Catheter angiography (DSA):

Lumbar puncture with opening pressure:

Vestibular testing:

Tinnitus-specific psychoacoustic measures:

CCS pearl: When ordering MRI for asymmetric SNHL on a CCS case, specifically choose "MRI brain with and without contrast, IAC protocol" — generic "MRI head" may miss small intracanalicular schwannomas.

Board pearl: Pulsatile tinnitus that decreases with ipsilateral jugular compression suggests a venous source (sigmoid sinus diverticulum, IIH-related stenosis), while one that does not change is more likely arterial (AV fistula, carotid).

Risk Stratification or First-Line Management Logic

— Cerumen removal if impacted

— Stop or substitute ototoxic medications when feasible (review with pharmacy)

— Treat middle ear pathology (effusion, otitis, cholesteatoma)

— Address vascular lesion (embolization, surgery for glomus, stenting for venous stenosis)

— Control BP, glucose, lipids — cardiovascular risk factors correlate with tinnitus severity

— Non-bothersome tinnitus: reassurance, education, watchful waiting, lifestyle counseling

— Bothersome tinnitus (interferes with sleep, mood, concentration, work): structured intervention

— Recent (<6 months): education and watchful waiting are reasonable; many resolve or habituate

— Persistent (≥6 months) and bothersome: active intervention warranted

— Audiologic evaluation for all

— Hearing aids if accompanied by hearing loss amenable to amplification (often dramatically reduces tinnitus perception)

— Cognitive behavioral therapy (CBT) — strongest evidence for reducing distress and improving quality of life

— Education and counseling for all

— Antidepressants, anticonvulsants, anxiolytics, intratympanic steroids as primary tinnitus therapy (they may be used for comorbid depression/anxiety, not for tinnitus itself)

— Ginkgo biloba, melatonin, zinc — insufficient evidence

— Transcranial magnetic stimulation outside research settings

— Background noise, white noise generators, hearing aids with masker function, smartphone apps

— Helps habituation but not curative

Step 1 — Identify and treat secondary causes:

Step 2 — Stratify by bother:

Step 3 — Stratify by duration:

AAO-HNS strong recommendations for persistent bothersome tinnitus:

AAO-HNS recommends AGAINST routinely:

Sound therapy (optional, evidence variable):

Step 3 management: A 65-year-old man with bilateral high-frequency hearing loss and bothersome ringing for 1 year — first-line stepwise plan: education → audiology referral → hearing aids → CBT if persistent distress. Do not start SSRI or gabapentin reflexively.

Board pearl: CBT is the single intervention with the most robust evidence for reducing tinnitus-related distress — it does not abolish the sound but reduces suffering and disability.

Pharmacotherapy — First-Line Drug Regimen

— SSRIs (sertraline, escitalopram) — first-line for tinnitus patients with depression or anxiety; reduces distress, not tinnitus loudness per se

— SNRIs (duloxetine, venlafaxine) — alternative

— Avoid TCAs as first-line (anticholinergic burden, cardiac risk in elderly), though nortriptyline has historic data

— Monitor: PHQ-9/GAD-7 at 4–6 weeks, then quarterly

— Sleep hygiene first

— Trazodone 25–100 mg qhs or melatonin 3–5 mg for short-term insomnia related to tinnitus

— Avoid chronic benzodiazepines (dependence, falls, cognitive risk in elderly) — short courses only if disabling

— Sudden sensorineural hearing loss with tinnitus: oral prednisone 60 mg daily × 7–14 days then taper, started within 2 weeks; intratympanic dexamethasone as salvage or primary if systemic contraindicated

— Ménière disease: low-salt diet, HCTZ 25 mg/triamterene, vestibular suppressants (meclizine) for acute vertigo; intratympanic gentamicin or dexamethasone for refractory

— Otosyphilis: IV penicillin G × 10–14 days plus corticosteroids

— Autoimmune inner ear disease: high-dose prednisone, then steroid-sparing agents

— High-dose aspirin/NSAIDs (reversible), aminoglycosides, IV loop diuretics, cisplatin, vancomycin troughs >20, quinine, sildenafil (rare), hydroxychloroquine (rare)

— Gabapentin, pregabalin, clonazepam, ginkgo biloba, lipoflavonoids, betahistine (not FDA-approved in US) — AAO-HNS recommends against as primary tinnitus therapy

Critical concept: No medication is FDA-approved or guideline-recommended specifically for tinnitus. Pharmacotherapy targets comorbid conditions (depression, anxiety, insomnia) or specific underlying causes (Ménière, SSNHL, vascular).

Medications for comorbid mood/anxiety driving tinnitus distress:

Sleep optimization:

Disease-specific pharmacotherapy:

Medications to STOP or reduce (ototoxic):

What NOT to prescribe routinely:

Key distinction: Treating depression/anxiety with SSRI in a tinnitus patient is appropriate; prescribing SSRI for the tinnitus itself is not evidence-supported and is a board distractor.

Board pearl: For sudden unilateral hearing loss with new tinnitus, start oral steroids immediately even before MRI results — the therapeutic window is approximately 2 weeks.

Procedures / Revascularization / Invasive Management

— Indicated when tinnitus accompanies amplifiable hearing loss

— Improve auditory input, reduce central gain, mask tinnitus

— Many modern aids include integrated tinnitus maskers (broadband noise generators)

— Insurance coverage variable; advocate for veterans (VA covers), Medicare Advantage often partial

— Severe-to-profound SNHL with poor hearing aid benefit

— Tinnitus often improves substantially after implantation in addition to hearing restoration

— Consider in single-sided deafness with disabling tinnitus

— Tabletop sound generators, in-ear maskers, smartphone apps

— Tinnitus Retraining Therapy (TRT): structured combination of directive counseling + sound therapy over 12–24 months

— Glomus tympanicum/jugulare: surgical excision ± preoperative embolization

— Dural AV fistula: endovascular embolization (gold standard) ± surgery

— Sigmoid sinus diverticulum/dehiscence: sigmoid sinus wall reconstruction

— Venous sinus stenosis with IIH: weight loss + acetazolamide first; venous sinus stenting for refractory cases with measurable pressure gradient

— Superior canal dehiscence: middle fossa or transmastoid plugging/resurfacing

— Otosclerosis: stapedectomy/stapedotomy

— Vestibular schwannoma: observation (small, stable), stereotactic radiosurgery, or microsurgical resection — tinnitus may persist regardless

— 6–8 weekly sessions, in person or via validated internet-based programs

— Reduces THI/TFI scores, improves sleep and mood, durable benefit

— Bimodal neuromodulation (paired auditory + tongue stimulation), repetitive TMS, vagus nerve stimulation

Hearing aids (most impactful "device" intervention):

Cochlear implants:

Sound therapy devices:

Procedures for specific structural causes:

Cognitive behavioral therapy (CBT) — non-procedural but highest-yield intervention:

Investigational (do not pick on boards as first-line):

CCS pearl: On a CCS pulsatile tinnitus case with confirmed dural AV fistula, the correct next step is neuro-interventional referral for embolization — not anticoagulation, not steroids.

Board pearl: A patient with bothersome tinnitus AND hearing loss in the speech frequencies — the single most cost-effective intervention is a hearing aid, not medication.

Special Populations — Elderly and Renal/Hepatic Impairment

— Tinnitus prevalence peaks here; usually coexists with presbycusis

— Cognitive impact: untreated hearing loss accelerates cognitive decline; aggressive amplification may also reduce tinnitus burden

— Polypharmacy review (Beers Criteria):

— Avoid TCAs, first-gen antihistamines, benzodiazepines for tinnitus-related sleep complaints — fall risk, delirium

— Loop diuretics: use lowest effective dose; IV furosemide >40 mg rapid push is ototoxic

— Reconsider aminoglycosides; if needed, use single daily dosing with TDM

— Depression screening is essential — late-life depression frequently presents with somatic complaints including tinnitus distress

— Falls and balance: tinnitus often coexists with vestibular dysfunction; refer to vestibular rehab

— Hearing aid uptake low due to cost/stigma — OTC hearing aids (FDA-approved 2022) for mild-moderate loss expand access

— Avoid aminoglycosides when possible; if essential, extended-interval dosing and audiometric monitoring before and during therapy

— Vancomycin: target AUC-guided dosing; troughs >20 mg/L associated with ototoxicity

— Loop diuretics: higher doses required in CKD/HF, increase ototoxicity risk — give as infusion rather than IV push when high doses needed

— Gabapentin/pregabalin (occasionally tried off-label for tinnitus — not recommended): require dose reduction in CKD; risk of myoclonus, sedation

— Cisplatin chemo: consider sodium thiosulfate otoprotection in pediatric oncology per FDA approval; for adults, dose adjustment and audiometric monitoring

— SSRIs: start low (sertraline 25 mg); avoid duloxetine in significant hepatic dysfunction

— Acetaminophen preferred for analgesia over high-dose NSAIDs (ototoxic at high doses)

— Mirtazapine for sleep + appetite if depression present, dose reduce in hepatic impairment

Elderly (≥65):

Renal impairment:

Hepatic impairment:

Step 3 management: An 82-year-old on furosemide 80 mg IV BID for HF with new tinnitus — switch to continuous infusion or PO equivalent, check renal function, audiogram, review concurrent ototoxins before adding any tinnitus-specific therapy.

Board pearl: In elderly patients, untreated hearing loss is now a modifiable dementia risk factor (Lancet Commission) — treating it serves dual purpose of cognitive preservation and tinnitus relief.

Special Populations — Pregnancy, Pediatrics, and Other Subgroups

— New or worsened tinnitus may occur due to physiologic hyperdynamic circulation, anemia, increased intracranial venous pressure

— Pulsatile tinnitus in pregnancy — consider IIH (weight gain, preexisting risk), preeclampsia-related cerebral edema, dural sinus thrombosis (hypercoagulable state)

— Imaging: MRI without gadolinium is safe; avoid gadolinium (category C; crosses placenta) unless essential; CT/CTA only if benefit outweighs fetal radiation risk

— Sudden SNHL in pregnancy: intratympanic dexamethasone preferred over systemic steroids to minimize fetal exposure

— Avoid: high-dose aspirin/NSAIDs (oligohydramnios, ductus closure after 20 weeks), aminoglycosides (fetal ototoxicity)

— Postpartum follow-up: many pregnancy-related tinnitus cases resolve; reassess at 6 weeks

— Tinnitus in children is underreported — children rarely volunteer the symptom; ask directly when behavioral/school issues arise

— Most common causes: otitis media with effusion, noise exposure (personal audio devices, concerts), migraine

— Workup: otoscopy, tympanometry, age-appropriate audiometry

— Cisplatin chemotherapy: FDA-approved sodium thiosulfate for otoprotection in pediatric patients with localized solid tumors

— Avoid ototoxic medications; counsel on hearing protection at concerts and with personal audio devices (60/60 rule: <60% volume, <60 minutes)

— CBT and parental reassurance highly effective; medications rarely indicated

— Tinnitus is the #1 service-connected disability in US veterans

— Combine VA audiology, mental health (high PTSD comorbidity), and CBT services

— Custom musician earplugs (attenuate uniformly, preserve fidelity), routine audiometric surveillance, OSHA hearing conservation programs

— Bidirectional relationship — treat both

— Suicide risk screen in severely bothered patients; tinnitus has documented association with suicidal ideation

Pregnancy:

Pediatrics:

Veterans/military:

Musicians and occupational noise exposure:

Patients with depression/PTSD/anxiety:

Key distinction: Pulsatile tinnitus in a young obese pregnant woman with headache — think IIH, evaluate with fundoscopy and MRV (no gadolinium); pulsatile tinnitus in a postpartum woman with focal deficits — think cerebral venous sinus thrombosis.

Board pearl: Always counsel adolescents about personal audio device volume and concert exposure — noise-induced hearing loss in this group is rising and is entirely preventable.

Complications and Adverse Outcomes

— Major depressive disorder — prevalence 2–3× general population among bothered tinnitus patients

— Generalized anxiety, panic disorder

— Insomnia and chronic sleep deprivation — bidirectionally worsens tinnitus perception

— Suicidal ideation and completed suicide — documented association, especially with severe THI scores; routinely screen

— Social isolation, occupational disability, reduced productivity

— Concentration difficulty, executive dysfunction

— Untreated hearing loss (often coexisting) is a modifiable risk factor for dementia

— Untreated vestibular schwannoma: progressive hearing loss, facial nerve compromise, brainstem compression

— Untreated SSNHL: permanent hearing loss if steroids delayed beyond ~4–6 weeks

— Untreated dural AV fistula: intracranial hemorrhage, venous infarction, progressive neurologic decline

— Untreated IIH: permanent vision loss from optic atrophy — the most feared, preventable complication

— Untreated Ménière: progressive SNHL, drop attacks (Tumarkin), falls

— Otosclerosis progression: worsening conductive then mixed loss

— Ototoxic medication use uncorrected → permanent SNHL

— Inappropriate long-term benzodiazepine prescribing → dependence, falls, cognitive decline

— Excessive imaging → incidentalomas, anxiety, cost

— Stapedectomy complications: dead ear, vertigo, facial nerve injury

— Lost productivity (estimated billions annually in US)

— High utilization of unproven supplements and "tinnitus cures" — financial exploitation

Psychological complications:

Cognitive effects:

Disease-specific complications:

Iatrogenic complications:

Health system & economic complications:

Step 3 management: A patient with persistent bothersome tinnitus reports passive suicidal ideation. Immediate steps: safety assessment, restrict access to means, urgent mental health referral or ED if active plan, initiate SSRI, refer for CBT specifically validated for tinnitus, and provide crisis line resources (988).

Board pearl: The most catastrophic preventable complication of pulsatile tinnitus is permanent vision loss from missed IIH — fundoscopy in every pulsatile tinnitus patient with headache or visual symptoms is a non-negotiable bedside maneuver.

When to Escalate Care — ICU, Consult, or Inpatient Triage

— Sudden sensorineural hearing loss (over hours to 3 days) with tinnitus → urgent ENT, start oral steroids same day, audiogram within 14 days, MRI within weeks

— Tinnitus with focal neurologic deficits (facial weakness, ataxia, dysarthria) → stroke pathway, CT/CTA, neurology

— Pulsatile tinnitus with severe headache, papilledema, or visual change → suspect IIH or venous sinus thrombosis; admit for LP, imaging, ophthalmology

— Tinnitus with vertigo, vomiting, and inability to ambulate → posterior circulation stroke vs vestibular neuritis; HINTS exam, MRI

— Suicidal ideation with plan → psychiatric emergency, ED disposition

— Acute traumatic tinnitus with TM rupture, CSF otorrhea, or temporal bone fracture → ENT/neurosurgery

— Unilateral tinnitus

— Asymmetric hearing loss

— Pulsatile tinnitus (after initial imaging if available)

— Tinnitus with otorrhea, otalgia, or mass

— Suspected Ménière, otosclerosis, cholesteatoma, schwannoma

— Failed first-line conservative management at 3–6 months

— All chronic tinnitus patients for baseline audiogram

— Hearing aid candidacy assessment

— Sound therapy/TRT initiation

— PHQ-9 ≥10 or GAD-7 ≥10

— Severe THI (>56) or TFI (>50)

— Sleep disturbance refractory to hygiene measures

— CBT-trained therapist specifically for tinnitus when available

— Dural AV fistula, venous sinus stenosis, vestibular schwannoma, IIH refractory to medical management

— Coordinate referrals, manage comorbidities, screen for depression at each visit, deprescribe ototoxic medications, reinforce hearing protection

Emergency department / urgent escalation:

ENT referral (outpatient, expedited):

Audiology referral (outpatient, routine):

Mental health referral:

Neurology/neurosurgery/interventional radiology:

Primary care role — longitudinal hub:

CCS pearl: On a CCS case of sudden unilateral hearing loss with tinnitus, the correct sequence: same-day oral prednisone → urgent ENT referral → audiogram within 14 days → MRI IAC with contrast. Delaying steroids while awaiting imaging is a classic CCS error.

Board pearl: Unilateral tinnitus is an ENT referral until proven otherwise — never reassure without imaging or specialist input.

Key Differentials — Same-Category Causes (Otologic)

— Bilateral, symmetric, gradual high-frequency SNHL in older adults

— Hearing aids improve both hearing and tinnitus

— Bilateral 4-kHz notch on audiogram; occupational or recreational exposure history

— Prevention via hearing protection is key

— Young to middle-aged adults, often women, with progressive conductive then mixed loss

— Carhart notch at 2 kHz, Schwartze sign, family history; treat with stapedectomy or hearing aid

— Triad/tetrad: episodic vertigo (≥20 min), fluctuating low-frequency SNHL, tinnitus, aural fullness

— Diagnosis clinical; ECochG supportive; treat with low-salt diet, diuretic, vestibular suppressants, intratympanic therapy

— Unilateral tinnitus + asymmetric SNHL + poor word recognition disproportionate to pure-tone loss

— MRI IAC with contrast; small lesions observed, larger require radiosurgery or microsurgery

— Easily missed reversible cause; remove and reassess

— Conductive loss, aural fullness; treat underlying cause

— Chronic ear drainage, white debris on otoscopy, conductive loss; surgical

— Autophony (hearing own voice/heartbeat loudly), Tullio phenomenon (sound-induced vertigo), pulsatile tinnitus; CT temporal bone

— Autophony, tinnitus that fluctuates with breathing/position

— Aminoglycosides, cisplatin, loop diuretics, salicylates (high-dose, reversible), vancomycin

— Idiopathic vs viral vs vascular; start steroids immediately

— Bilateral rapidly progressive SNHL over weeks-months; high-dose steroid trial

— Tertiary syphilis or HIV coinfection; treat with IV penicillin + steroids

Presbycusis:

Noise-induced hearing loss:

Otosclerosis:

Ménière disease:

Vestibular schwannoma (acoustic neuroma):

Cerumen impaction:

Otitis media / middle ear effusion:

Cholesteatoma:

Superior semicircular canal dehiscence:

Eustachian tube dysfunction / patulous eustachian tube:

Ototoxic medication–induced:

Sudden sensorineural hearing loss:

Autoimmune inner ear disease:

Otosyphilis:

Key distinction: Word recognition score disproportionately poor relative to pure-tone audiogram in a unilateral case = retrocochlear lesion (schwannoma) — escalate to MRI even if pure-tone asymmetry is modest.

Board pearl: Episodic vertigo + low-frequency SNHL + roaring tinnitus + aural fullness = Ménière; persistent unilateral tinnitus + asymmetric high-frequency SNHL + balance issues = schwannoma. These two are the most commonly confused on Step 3.

Key Differentials — Other-Category Causes

— Carotid stenosis (atherosclerotic) — older adults with vascular risk factors; carotid duplex, CTA

— Fibromuscular dysplasia — young to middle-aged women; "string of beads" on imaging

— Dural arteriovenous fistula — pulsatile tinnitus often unilateral; CTA/MRA, DSA confirms; embolization curative

— Venous sinus stenosis — often associated with IIH; MRV

— Sigmoid sinus diverticulum/dehiscence — surgical reconstruction

— Aberrant internal carotid artery in middle ear — red mass on otoscopy; CT temporal bone

— High-riding/dehiscent jugular bulb

— Persistent stapedial artery

— Glomus tympanicum/jugulare (paraganglioma) — pulsatile tinnitus, red retrotympanic mass, brisk pulsation; CT/MRI; surgery or radiation

— Meningioma of CPA — mimics schwannoma on imaging

— Multiple sclerosis — brainstem plaques may cause tinnitus + other CN findings

— Vestibular migraine — episodic vertigo, tinnitus, photophobia, headache; treat as migraine

— Idiopathic intracranial hypertension — obese reproductive-age women, headache, papilledema, pulsatile tinnitus, visual obscurations

— Cerebral venous sinus thrombosis — postpartum, OCP use, hypercoagulable states

— Anemia, hyperthyroidism, pregnancy — hyperdynamic states cause pulsatile tinnitus

— Diabetes, hyperlipidemia, hypertension — correlate with tinnitus severity

— TMJ dysfunction — clicking, modulation with jaw movement; physical therapy, occlusal splints

— Cervical spine pathology — somatosensory tinnitus modulated by neck movement

— Palatal or middle ear myoclonus — rhythmic clicking, audible on auscultation; muscle relaxants, botulinum toxin

— Auditory hallucinations (formed voices, music) — distinct from tinnitus; suggests psychiatric or temporal lobe pathology

— Musical ear syndrome — complex sound perception in older adults with severe hearing loss; reassure

— Heavy metals (lead, mercury), carbon monoxide exposure, organic solvents

Vascular (pulsatile tinnitus):

Neoplastic:

Neurologic:

Metabolic/endocrine:

Musculoskeletal:

Psychiatric/functional:

Toxic/environmental:

Step 3 management: Pulsatile tinnitus in a 32-year-old obese woman with daily headache and transient visual obscurations — fundoscopy, MRI/MRV brain, then LP with opening pressure. Do not anchor on "primary headache."

Board pearl: Auditory hallucinations of formed voices or music are NOT tinnitus — evaluate for psychiatric disorder, dementia, or temporal lobe seizure.

Secondary Prevention / Discharge Medications / Long-Term Plan

— OSHA standard: hearing conservation program when 8-hr TWA ≥85 dB

— Personal: foam earplugs (NRR ~29 dB), earmuffs, custom musician plugs

— Counsel veterans, construction workers, musicians, hunters, factory workers

— Maintain a documented ototoxic medication list in the chart

— Review at every medication reconciliation

— Coordinate with oncology, ID, nephrology when ototoxic agents are essential — request lowest effective dose, monitor audiograms before/during therapy

— BP control (<130/80), HbA1c per ADA targets, lipid management, smoking cessation

— Correlates with tinnitus severity and reduces vascular pulsatile tinnitus progression

— Battery replacement, cleaning, annual audiology re-evaluation

— Reprogramming as hearing changes

— OTC aids appropriate for mild-moderate; prescription for moderate-severe or complex losses

— Booster sessions if symptoms flare during stress, medical illness, or sleep disruption

— Internet-based CBT for tinnitus has growing evidence and improves access

— Bedside sound generators, fan, white noise apps

— Avoid alcohol and caffeine close to bedtime

— Treat OSA (often coexisting, worsens tinnitus distress)

— PHQ-9 and GAD-7 at routine intervals (every 3–6 months in bothered patients)

— Continue SSRI/SNRI for comorbid depression/anxiety; reassess need annually

— Ménière: sodium restriction <1500–2000 mg/day, limit caffeine and alcohol

— General: weight management (relevant for IIH), regular exercise, stress reduction

— Pneumococcal, influenza, COVID — reduce risk of ear infections and viral SNHL exacerbations

— American Tinnitus Association, AAO-HNS patient pages, VA tinnitus self-management workbook

Hearing protection (primary AND secondary prevention):

Avoid further ototoxic exposure:

Cardiovascular risk factor modification:

Hearing aid maintenance:

CBT continuation and relapse prevention:

Sleep hygiene and management:

Mood monitoring:

Diet and lifestyle:

Vaccination and infection prevention:

Patient education resources:

Step 3 management: Discharge plan for a 55-year-old construction worker with new persistent bothersome tinnitus and hearing loss: (1) hearing aids via audiology, (2) CBT referral, (3) employer-mandated hearing conservation program enrollment, (4) cardiovascular risk modification, (5) PHQ-9 follow-up in 6 weeks.

Board pearl: Hearing protection counseling is the single most effective prevention strategy for noise-induced tinnitus — document at every visit for at-risk occupations.

Follow-Up, Monitoring Parameters, and Rehab/Counseling

— Initial diagnosis: 4–6 weeks to assess response to first-line interventions (cerumen removal, medication review, audiology referral status)

— After audiology/hearing aid fitting: 6–8 weeks to assess benefit

— CBT course: weekly × 6–8 sessions, then maintenance every 3–6 months

— Bothersome chronic tinnitus on stable regimen: every 6–12 months

— Comorbid depression/anxiety on SSRI: 4–6 weeks, then 3 months, then 6 months

— Tinnitus Handicap Inventory (THI): 25-item, 0–100; >36 = moderate handicap

— Tinnitus Functional Index (TFI): 25-item, more sensitive to change; clinically meaningful reduction ≥13 points

— PHQ-9 and GAD-7 at each follow-up

— Audiogram annually if hearing loss progressive; every 2–3 years if stable

— Insomnia Severity Index (ISI) when sleep is a focus

— New unilaterality, asymmetric hearing change, new vertigo, new neuro deficits → ENT/neurology, MRI

— New pulsatile character → vascular workup

— Worsening THI/TFI despite therapy → reassess diagnosis, intensify CBT, consider psychiatric comorbidity

— Suicidal ideation → emergent mental health

— Audiologic rehabilitation: counseling, sound therapy, hearing aid optimization

— Vestibular rehabilitation if balance/vestibular component (Ménière, vestibular schwannoma post-op)

— Vocational rehabilitation for occupational disability

— Validate the experience; tinnitus is real, not imagined

— Set realistic expectations: goal is habituation and reduced distress, not silence

— Explain the neurophysiological model (central gain) — patients improve when they understand

— Discourage spending on unproven supplements and "miracle cures"

— Document service connection for veterans (VA disability)

— Insurance prior authorization for hearing aids, CBT, MRI

— Telehealth CBT-for-tinnitus expands access in rural settings

Step 3 management: At 3-month follow-up, a patient with THI of 60 at baseline now reports THI of 45 after hearing aids and starting CBT — a meaningful improvement; continue current plan, add sleep hygiene focus, reassess in 3 months.

Board pearl: Habituation, not elimination, is the realistic goal of chronic tinnitus management — framing this early in counseling reduces patient frustration and improves adherence.

Ethical, Legal, and Patient Safety Considerations

— Stapedectomy for otosclerosis: discuss risk of dead ear (1–3%), vertigo, taste disturbance, facial nerve injury — even though hearing improvement likely, the bad outcome is devastating; document discussion

— Intratympanic gentamicin for Ménière: explicit consent regarding hearing loss risk (chemical ablation)

— Vestibular schwannoma observation vs treatment: shared decision-making essential; some patients prefer monitoring, others immediate intervention

— Cochlear implantation in single-sided deafness: discuss realistic tinnitus outcomes

— OSHA recordable hearing loss: Standard Threshold Shift (STS) — 10 dB average shift at 2, 3, 4 kHz in either ear — must be recorded and worker re-tested

— Occupational tinnitus may qualify for workers' compensation; documentation matters

— Veterans: tinnitus is the leading service-connected disability — assist with VA claims documentation

— Ototoxic medication continuation across care transitions — common error; explicitly flag aminoglycosides, cisplatin courses, IV loops at discharge

— Audiology and ENT referrals frequently fall through after hospital discharge; close-the-loop scheduling before discharge

— Sudden SNHL diagnosed in ED but not started on steroids before discharge — a documented quality gap; ED-to-ENT handoff protocols save hearing

— Suicide screening in severely bothered tinnitus patients is a standard of care, not optional

— Driving safety in patients with vertigo + tinnitus (Ménière drop attacks) — counsel and document

— Fall risk in elderly with balance complications — home safety, vestibular rehab, medication review

— Hearing aids historically not covered by traditional Medicare; OTC hearing aids (FDA 2022) democratize access for mild-moderate loss but require self-fitting literacy

— CBT availability disparities — telehealth and internet-based CBT improve reach

— Ethical duty to counsel against expensive supplements and "tinnitus cures" with no evidence

— Document discussion and provide reputable resources

— ADA protections for employees with hearing loss/tinnitus; help patients request reasonable accommodations

Disability accommodation:

Step 3 management: A patient discharged from the ED with "ear ringing" 5 days ago whose audiogram now shows severe unilateral SNHL — systems failure. Implement an ED-to-audiology fast-track, same-day steroid initiation protocol, and 14-day audiogram scheduling at discharge. This is a recurring patient-safety theme.

Board pearl: Failure to start steroids for sudden SNHL within the therapeutic window is the most common medicolegal and patient-safety failure in tinnitus care — own this transition.

High-Yield Associations and Rapid-Fire Clinical Facts

Unilateral tinnitus + asymmetric SNHL + poor word recognition → vestibular schwannoma → MRI IAC with contrast

Pulsatile tinnitus + obese reproductive-age woman + headache + papilledema → IIH → MRV, LP, acetazolamide, weight loss

Pulsatile tinnitus + bruit over mastoid + neuro deficits → dural AV fistula → CTA/DSA → embolization

Episodic vertigo + fluctuating low-frequency SNHL + roaring tinnitus + aural fullness → Ménière disease

Conductive hearing loss + Carhart notch at 2 kHz + Schwartze sign → otosclerosis

Pulsatile tinnitus + red retrotympanic mass → glomus tympanicum

Tinnitus + autophony + Tullio phenomenon → superior semicircular canal dehiscence → CT temporal bone

Sudden unilateral hearing loss + tinnitus → start oral prednisone within 2 weeks; MRI IAC

4-kHz audiogram notch → noise-induced hearing loss

Bilateral high-frequency sloping SNHL in elderly → presbycusis; hearing aids treat both loss and tinnitus

Bilateral rapidly progressive SNHL over weeks → autoimmune inner ear disease → high-dose steroid trial

Rhythmic clicking audible to examiner → palatal or middle ear myoclonus → muscle relaxants, botulinum toxin

Tinnitus modulated by jaw clench or neck rotation → somatosensory tinnitus; PT

Aminoglycoside, cisplatin, IV loop diuretic, vancomycin, high-dose salicylate → ototoxicity

Tinnitus + immunocompromised + fluctuating SNHL → consider otosyphilis → RPR/FTA-ABS → IV penicillin + steroids

Strongest evidence-based intervention for distress → CBT

Most cost-effective intervention when hearing loss coexists → hearing aids

AAO-HNS recommends AGAINST routine: antidepressants for tinnitus alone, anticonvulsants, benzodiazepines, ginkgo, melatonin, zinc, intratympanic steroids, TMS as primary tinnitus therapy

#1 service-connected disability in US veterans → tinnitus

Tinnitus + suicidal ideation → mental health emergency

Untreated hearing loss → modifiable dementia risk factor (Lancet Commission)

OTC hearing aids FDA-approved since 2022 for mild-moderate loss in adults

High-dose aspirin tinnitus → reversible on discontinuation

Board pearl: Pattern recognition wins the tinnitus question — the laterality, character (pulsatile vs not), and associated features (vertigo, headache, hearing loss type) virtually always give the diagnosis on Step 3 stems.

Board Question Stem Patterns

— Gabapentin or clonazepam as first-line for tinnitus

— Ginkgo biloba, melatonin, zinc supplements

— Routine MRI for bilateral symmetric non-pulsatile tinnitus

— Reassurance only when red flags present

Stem 1 — Vestibular schwannoma: A 52-year-old reports 6 months of right-sided ringing and progressive difficulty understanding speech on the phone with the right ear. Audiogram shows asymmetric high-frequency SNHL with word recognition score 40% on right, 96% on left. Next step? → MRI brain with IAC contrast.

Stem 2 — Sudden SNHL: A 45-year-old wakes with unilateral hearing loss and ringing 3 days ago. Audiogram confirms severe SNHL on the affected side. Next step? → Oral prednisone 60 mg daily × 1–2 weeks, urgent ENT, MRI IAC.

Stem 3 — IIH: A 28-year-old obese woman with daily headache, transient visual obscurations, and whooshing pulsatile tinnitus. Fundoscopy shows papilledema. Next step? → MRI/MRV brain, then LP with opening pressure; treat with acetazolamide + weight loss.

Stem 4 — Ménière: A 50-year-old has episodic 1–2 hour vertigo, low-pitched roaring tinnitus, aural fullness, and fluctuating hearing. Diagnosis? → Ménière disease. Initial treatment? → Low-salt diet, HCTZ/triamterene, meclizine for acute attacks.

Stem 5 — Otosclerosis: A 35-year-old woman with bilateral progressive hearing loss, family history, and tinnitus. Audiogram: conductive loss with 2-kHz Carhart notch. Best management? → Stapedectomy or hearing aids.

Stem 6 — Noise-induced + bothersome: A 60-year-old retired construction worker with bilateral 4-kHz notch SNHL and chronic ringing affecting sleep. Best next step? → Audiology referral for hearing aids; CBT for distress. Not gabapentin, not SSRI as first move.

Stem 7 — Dural AV fistula: A 55-year-old with unilateral pulsatile tinnitus and a bruit over the mastoid. CTA shows abnormal vascularity. Next step? → Cerebral angiography and embolization.

Stem 8 — Cerumen: An 80-year-old with new tinnitus. Otoscopy: impacted cerumen. Next step? → Cerumen removal, then reassess. Cheap, fast, often curative.

Stem 9 — Ototoxicity: A patient on IV gentamicin and IV furosemide for endocarditis develops bilateral tinnitus and hearing loss. Next step? → Discontinue/modify ototoxins, audiogram, ID consult for alternative regimen.

Stem 10 — Suicidality: A patient with severe tinnitus reports passive suicidal thoughts. Best next step? → Safety assessment and urgent mental health referral, initiate SSRI, refer for CBT.

Common distractors to AVOID:

Board pearl: When a stem describes unilateral, pulsatile, sudden, or neurologically concerning tinnitus — never pick "reassure and follow up." Pick imaging or specialist referral.

One-Line Recap

Tinnitus is a symptom, not a disease — work it up by laterality, character, and red flags; treat reversible causes, optimize hearing with amplification when loss coexists, and use CBT as the evidence-based backbone for chronic bothersome cases.

— Bilateral, symmetric, non-pulsatile → audiogram-based outpatient workup; no routine MRI

— Unilateral, asymmetric, sudden, or pulsatile → MRI IAC with contrast or CTA/MRV; specialist referral; same-day steroids for sudden SNHL

— Always otoscopy, medication review, and PHQ-9/GAD-7 screening

— Hearing aids when hearing loss coexists — most cost-effective intervention

— CBT — strongest evidence for reducing distress and improving quality of life

— Education and habituation framing — goal is reduced suffering, not silence

— Treat comorbid depression, anxiety, insomnia with appropriate pharmacotherapy

— Avoid routine prescribing of antidepressants, anticonvulsants, benzodiazepines, or supplements specifically for tinnitus (AAO-HNS recommends against)

— Sudden SNHL → oral steroids within 2 weeks, do not delay for imaging

— Pulsatile tinnitus in obese reproductive-age woman with headache → rule out IIH before vision is lost

— Unilateral tinnitus + asymmetric SNHL + poor word recognition → MRI for vestibular schwannoma

— Severe tinnitus + suicidal ideation → mental health emergency

— Hearing protection in occupational and recreational noise exposure

— Maintain ototoxic medication list; review at every transition of care

— Cardiovascular risk factor modification correlates with tinnitus severity
