Meniere disease: diagnosis and management

Clinical Overview and When to Suspect Meniere Disease

— Peak onset 40–60 years, slight female predominance

— Usually unilateral at onset; ~30–50% become bilateral over years

— Prevalence ~200/100,000 in the US; familial clustering in ~10%

— Adult presenting with recurrent spontaneous vertigo episodes lasting 20 minutes to 12 hours (not seconds, not days)

— Low-frequency SNHL documented on audiogram, fluctuating early in disease

— Tinnitus and ear fullness that crescendo before or during an attack

— Episodes occur in clusters separated by months of remission

— Impaired endolymph resorption at the endolymphatic sac → hydrops → rupture or distortion of Reissner membrane → mixing of endolymph and perilymph → transient hair cell dysfunction

— Genetic, autoimmune, vascular, and viral triggers have been implicated; no single cause confirmed

— Rule out vestibular migraine (overlapping features, far more common)

— Rule out BPPV (seconds-long positional vertigo)

— Rule out vestibular neuritis (single prolonged episode, no hearing loss)

— Rule out acoustic neuroma (progressive unilateral SNHL ± imbalance)

Definition: Idiopathic inner ear disorder characterized by endolymphatic hydrops — excess endolymph distending the membranous labyrinth — producing episodic vertigo, fluctuating sensorineural hearing loss (SNHL), tinnitus, and aural fullness.

Epidemiology:

When to suspect in clinic:

Pathophysiology highlights:

Differential trigger thinking:

Step 3 management: First outpatient visit should always document a baseline audiogram before initiating therapy — diagnosis hinges on objective low-frequency SNHL, and you cannot trend hearing without a baseline.

Board pearl: The classic Meniere tetrad is episodic vertigo + fluctuating SNHL + tinnitus + aural fullness; absence of documented hearing loss should make you question the diagnosis and pursue alternatives.

Presentation Patterns and Key History

— Increasing aural fullness/pressure in the affected ear

— Tinnitus worsens or changes pitch (often low-pitched, roaring)

— Hearing becomes muffled or distorted

— Spontaneous spinning vertigo with nausea/vomiting

— Horizontal-torsional nystagmus, gait instability

— Patient typically lies still; movement worsens symptoms

— No loss of consciousness, no focal neuro deficits

— Residual disequilibrium, fatigue, mental fog

— Hearing may partially recover early in disease, becomes permanently impaired later

— Stage 1: fluctuating low-frequency SNHL, intermittent attacks

— Stage 2: more frequent attacks, progressive hearing loss across frequencies

— Stage 3: "burnout" — vertigo subsides but severe permanent hearing loss + chronic imbalance

— Sudden fall without warning or LOC due to abrupt vestibular discharge

— Marker of advanced disease, high fall-injury risk → escalate therapy

— Triggers: high salt intake, caffeine, alcohol, stress, poor sleep, MSG

— Family history of Meniere or migraine

— Migraine history (vestibular migraine mimics; many patients have both)

— Prior ototoxic exposure, head trauma, autoimmune disease, syphilis risk

— Vertigo lasting seconds (BPPV) or days continuously (neuritis/stroke)

— Bilateral simultaneous onset — think autoimmune inner ear disease

— Neurologic deficits, diplopia, dysarthria — posterior circulation stroke

Prodrome (minutes before attack):

Acute attack (20 min – 12 hours, never seconds, rarely >24 h):

Postictal phase (hours to days):

Disease course:

Tumarkin otolithic crisis (drop attack):

History pearls to elicit:

Red flags that argue against Meniere:

Key distinction: Vestibular migraine episodes can mimic Meniere exactly but lack documented fluctuating low-frequency SNHL — the audiogram is your tiebreaker.

Physical Exam Findings and Bedside Vestibular Assessment

— Otoscopy is normal in Meniere — no effusion, no perforation, no cholesteatoma

— Abnormal TM findings should redirect workup to otitis media, perilymph fistula, or superior canal dehiscence

— Weber lateralizes to the unaffected ear (sensorineural pattern)

— Rinne positive bilaterally (AC > BC) — confirms SNHL, not conductive

— Spontaneous nystagmus: During attack, horizontal-torsional, fast phase often beats away from affected ear (irritative) early, then toward affected ear (paretic) later

— Head impulse test (HIT): Catch-up saccade toward affected side suggests peripheral vestibular hypofunction — supports peripheral cause

— HINTS exam (Head Impulse, Nystagmus, Test of Skew): use in acute vestibular syndrome to differentiate peripheral vs central

– Peripheral (reassuring): abnormal HIT, unidirectional nystagmus, no skew

– Central (worrisome): normal HIT, direction-changing nystagmus, skew deviation → stroke workup

— Dix-Hallpike: Should be negative in Meniere (positive in BPPV)

— Romberg, tandem gait: May be unsteady acutely; should normalize between attacks early in disease

— Must be intact aside from CN VIII findings

— Any CN V, VII, or cerebellar signs → image the brain/IAC for vestibular schwannoma or stroke

— Pneumatic otoscopy producing vertigo/nystagmus suggests perilymph fistula or superior canal dehiscence, not Meniere

— Always check — orthostatic hypotension and dehydration from vomiting commonly confound the picture

General otologic exam:

Tuning fork tests (512 Hz):

Bedside vestibular battery:

Cranial nerve exam:

Fistula test:

Orthostatic vitals:

Board pearl: A normal HINTS exam in a patient with acute prolonged vertigo is reassuring for peripheral cause, but a single Meniere attack should not be your first diagnosis — first-ever prolonged vertigo deserves stroke consideration, especially in vasculopaths over 60.

Diagnostic Workup — Audiometry, Labs, and Initial Imaging

— Definite Meniere (Barany/AAO-HNS 2015 criteria):

– ≥2 spontaneous vertigo episodes lasting 20 min–12 h

– Audiometrically documented low-to-medium frequency SNHL in affected ear on ≥1 occasion

– Fluctuating aural symptoms (hearing, tinnitus, fullness) in affected ear

– Not better explained by another vestibular diagnosis

— Early: low-frequency SNHL (250–1000 Hz) with normal high frequencies — "upsloping" audiogram

— Late: flat or down-sloping loss across all frequencies

— Word recognition disproportionately poor relative to pure-tone loss

— TSH — hypothyroidism can mimic

— CBC, CMP — baseline

— FTA-ABS or RPR — neurosyphilis (otosyphilis mimics Meniere precisely)

— ANA, ESR/CRP — if bilateral or rapidly progressive → autoimmune inner ear disease

— HbA1c, lipid panel — vascular risk in older patients with vertigo

— Lyme serology if endemic exposure

— Vitamin B12, fasting glucose for atypical presentations

— MRI brain with IAC protocol, with gadolinium is the standard imaging study to exclude vestibular schwannoma, MS, and posterior fossa lesions — especially with unilateral SNHL, asymmetric tinnitus, or atypical features

— Not required to diagnose Meniere, but typically obtained at least once in workup

— CT temporal bone if superior semicircular canal dehiscence is suspected (sound/pressure-induced vertigo)

Audiometry (pure-tone + speech): The cornerstone test.

Tympanometry: Type A (normal) — rules out middle ear pathology.

Laboratory studies (selective, to exclude mimics):

Imaging:

Step 3 management: Any patient with asymmetric SNHL on audiogram warrants MRI with gadolinium of the IACs — missing a vestibular schwannoma is a high-stakes board and clinical error.

Diagnostic Workup — Advanced and Confirmatory Studies

— Measures cochlear potentials; elevated summating potential/action potential (SP/AP) ratio >0.4 suggests endolymphatic hydrops

— Supportive but not diagnostic in isolation; sensitivity ~60–70%

— Cervical VEMP (cVEMP): saccule/inferior vestibular nerve function

— Ocular VEMP (oVEMP): utricle/superior vestibular nerve

— Reduced amplitude on affected side supports peripheral vestibulopathy; also helps distinguish from superior canal dehiscence (where VEMPs are abnormally enhanced with low thresholds)

— Caloric testing often shows unilateral vestibular weakness (canal paresis ≥25%) on affected side

— Documents asymmetry, useful before ablative therapy

— Quantifies VOR gain across all six semicircular canals

— Often relatively preserved in early Meniere despite abnormal calorics — "caloric–vHIT dissociation" is a soft marker for Meniere

— Research/tertiary tool that can visualize endolymphatic hydrops directly

— Not standard in primary care; available at specialty vestibular centers

— Definite Meniere: clinical criteria + audiometric SNHL

— Probable Meniere: ≥2 vertigo or dizziness episodes 20 min–24 h + fluctuating aural symptoms, without required audiometric confirmation

— Diagnosis uncertain after audiogram and MRI

— Bilateral disease, drop attacks, or rapid hearing decline

— Failure of first-line conservative therapy after 3–6 months

Electrocochleography (ECochG):

Vestibular evoked myogenic potentials (VEMP):

Videonystagmography (VNG) / electronystagmography (ENG):

Video head impulse test (vHIT):

Delayed-contrast MRI with intratympanic or IV gadolinium:

Glycerol/dehydration test: Historical; rarely used today.

Diagnostic categorization (AAO-HNS 2015):

Referral threshold: Refer to otolaryngology/neurotology when:

Board pearl: Meniere remains a clinical diagnosis — advanced tests support, exclude mimics, or guide procedures but do not replace history + audiogram.

Risk Stratification and First-Line Management Logic

— Class A: no disability

— Class B–D: progressive impact on work/ADLs

— Class F: disabling, unable to work

1. Lifestyle and dietary modification (first-line for all patients)

2. Pharmacotherapy — daily preventive (diuretic ± betahistine) + acute attack rescue

3. Intratympanic steroid injection for refractory cases

4. Intratympanic gentamicin (chemical ablation) if hearing already poor

5. Surgical therapy — endolymphatic sac decompression, labyrinthectomy, vestibular nerve section

6. Cochlear implantation for end-stage hearing loss

— Sodium restriction to <1500–2000 mg/day — reduces endolymph volume fluctuation

— Distribute sodium evenly across the day; avoid bolus high-salt meals

— Limit caffeine (<1–2 cups coffee/day)

— Limit alcohol (vasoactive, exacerbates inner ear pressure shifts)

— Avoid MSG, nicotine

— Adequate hydration — counterintuitive but stabilizes osmotic shifts

— Regular sleep schedule

— Stress reduction (CBT, mindfulness)

— Migraine trigger avoidance if coexisting vestibular migraine

— Smoking cessation

— Treat anxiety/depression — bidirectional with vestibular disorders

— Control hypertension (loop/thiazide diuretics may serve dual purpose)

— Manage migraine separately

— Set expectations: disease is chronic and unpredictable, attacks will recur

— Symptom diary (frequency, duration, triggers, aural symptoms) to track response

— Driving safety counseling — many states require physician reporting of episodic incapacitating vertigo

Severity grading by functional impact (AAO-HNS):

Stepwise outpatient management algorithm:

Dietary cornerstones:

Lifestyle modifications:

Comorbidity optimization:

Patient education:

Step 3 management: Begin every newly diagnosed patient on low-sodium diet + caffeine/alcohol restriction + symptom diary before adding medications; reassess at 3 months with repeat audiogram and attack frequency review.

Pharmacotherapy — Maintenance and Acute Attack Regimens

— Thiazide-type diuretic:

– HCTZ 25 mg + triamterene 37.5 mg daily (Dyazide/Maxzide) is the classic regimen

– Rationale: reduces endolymph volume; modest evidence but widely used

– Monitor K+, Na+, Cr, uric acid; avoid in sulfa allergy (relative)

— Betahistine:

– Histamine H1 agonist/H3 antagonist; improves cochlear microcirculation

– Not FDA-approved in the US (available as compounded; standard in Europe/Canada at 16–24 mg TID)

— Strong patient-reported benefit; modest RCT evidence

— Migraine prophylaxis (if vestibular migraine overlap):

– Nortriptyline, topiramate, propranolol, verapamil

— Vestibular suppressants (short-term, <72 h to avoid impairing central compensation):

– Meclizine 25 mg PO q6h PRN — first-line outpatient antihistamine

– Dimenhydrinate alternative

– Diazepam 2–5 mg PO/IV for severe attacks — vestibular and anxiolytic effect

– Lorazepam 0.5–1 mg SL for rapid relief

— Antiemetics:

– Promethazine 25 mg PO/PR/IM — dual antihistamine/antiemetic

– Ondansetron 4–8 mg PO/IV — preferred if QTc allows

– Prochlorperazine 5–10 mg alternative

— Hydration — IV fluids for protracted vomiting

— Short oral prednisone bursts (e.g., 60 mg × 5–7 days, taper) for sudden hearing decline or severe cluster

— Intratympanic dexamethasone (covered next chunk) for refractory disease

— Aminoglycosides systemically — ototoxic

— High-dose loop diuretics, cisplatin, NSAIDs in excess — ototoxic risk

Maintenance (prophylactic) therapy:

Acute attack (rescue) pharmacotherapy:

Corticosteroids:

Medications to avoid:

Key distinction: Chronic daily meclizine is discouraged — it blunts central vestibular compensation and prolongs disequilibrium between attacks. Reserve for acute attacks only, max a few days at a time.

Procedural and Surgical Management

— Hearing-preserving, low risk

— Dexamethasone 4–10 mg/mL injected through TM into middle ear; absorbed via round window

— Series of 3 injections over weeks; repeat as needed

— Efficacy: ~70% reduce vertigo frequency; modest hearing benefit

— First-line procedural therapy when conservative measures fail and hearing is still useful

— Selective vestibulotoxicity preserves cochlea relatively but carries ~20–30% risk of additional hearing loss

— Highly effective for vertigo (~80–90% control)

— Reserved for patients with already-poor hearing in affected ear

— Titrated low-dose regimens reduce hearing loss risk

— Mastoidectomy approach to decompress sac

— Controversial efficacy; lower risk to hearing

— Option for hearing-preservation candidates failing intratympanic steroids

— Transects vestibular portion of CN VIII via posterior fossa craniotomy

— Definitive vertigo control (~95%) with hearing preservation

— Reserved for younger patients with serviceable hearing failing other treatments

— Significant surgical morbidity

— Surgical destruction of vestibular and cochlear end organs

— Sacrifices all hearing in operated ear

— Highest vertigo control (~95–99%)

— For patients with no serviceable hearing and disabling vertigo

— Outpatient device delivering pressure pulses via tympanostomy tube

— Modest evidence; option for medication-refractory patients avoiding surgery

— For end-stage profound SNHL, particularly in bilateral Meniere

Stepwise escalation when medical therapy fails (≥6 months):

Intratympanic dexamethasone injection:

Intratympanic gentamicin (chemical labyrinthectomy):

Endolymphatic sac surgery (decompression or shunt):

Vestibular nerve section:

Labyrinthectomy:

Meniett device (low-pressure pulse generator):

Cochlear implant:

Step 3 management: When referring for procedure, the decisive variable is residual hearing — preserve it with intratympanic steroids first; reserve gentamicin and labyrinthectomy for ears already non-serviceable.

Special Populations — Elderly and Renal/Hepatic Impairment

— Higher fall risk during attacks and from Tumarkin drop attacks → home safety assessment, PT referral, remove throw rugs, install grab bars

— Polypharmacy concerns:

– Anticholinergic burden from meclizine, promethazine — increases delirium, urinary retention, cognitive decline (Beers criteria caution)

– Benzodiazepines increase fall and fracture risk (Beers criteria — avoid)

– Prefer ondansetron for antiemesis over promethazine when possible

— Diuretic risks: dehydration, hyponatremia, hypokalemia, orthostatic hypotension — monitor electrolytes at 2 weeks, then quarterly

— Vascular vertigo mimics more common — lower threshold for MRI/MRA

— Hearing aids early — presbycusis compounds Meniere SNHL

— Thiazides lose efficacy at eGFR <30 — switch to loop diuretic if needed, but loop diuretics are ototoxic at high doses; use cautiously

— Adjust gabapentin (if used for vestibular symptoms) per CrCl

— Avoid NSAIDs for any concomitant pain — worsen renal function and may potentiate ototoxicity

— Contrast MRI: use macrocyclic gadolinium at eGFR 30–60; avoid at eGFR <30 unless essential (NSF risk, though low with modern agents)

— Reduce benzodiazepine doses; prefer lorazepam, oxazepam, temazepam (no active metabolites, glucuronidation only)

— Caution with prochlorperazine (hepatic metabolism)

— Topiramate dose adjustment if used for migraine overlap

— Check QTc before ondansetron, especially with concomitant QT-prolonging agents

— Watch BP with diuretics added to existing antihypertensives

— Vertigo and hearing loss accelerate cognitive decline; coordinate with geriatrics

Elderly patients (>65):

Renal impairment (CKD stage 3–5):

Hepatic impairment:

Cardiac comorbidity:

Cognitive impairment:

Board pearl: In any elderly patient on meclizine or benzodiazepines, document that you assessed and discussed fall and cognitive risk — Beers criteria adherence is testable and reflects real Step 3 ambulatory care.

Special Populations — Pregnancy, Pediatrics, and Migraine Overlap

— Meniere disease often improves during pregnancy (hormonal/fluid shifts) but can flare postpartum

— Avoid teratogens:

– Thiazides — generally avoided in pregnancy (volume depletion, fetal electrolyte issues); discontinue when planning pregnancy

– Benzodiazepines — avoid, especially first trimester (cleft palate signal) and near term (neonatal withdrawal/sedation)

– Topiramate — teratogenic (cleft lip/palate), avoid if used for migraine overlap

— Safer options:

– Meclizine (Category B equivalent) — acceptable for acute attacks, lowest effective dose

– Dimenhydrinate, diphenhydramine — acceptable

– Ondansetron — generally safe; first-trimester cardiac signal is small/debated, shared decision

– Promethazine — acceptable short-term

— Emphasize non-pharmacologic measures: low-sodium diet, hydration, sleep, vestibular rehab

— Coordinate with obstetrics for any new med

— Meclizine and diphenhydramine pass into milk; may reduce supply and sedate infant — use sparingly

— Ondansetron compatible with breastfeeding

— Meniere in children is rare (<3% of cases); always pursue alternative diagnoses first:

– Vestibular migraine of childhood — far more common

– Benign paroxysmal vertigo of childhood (seconds–minutes, no hearing loss, often migraine precursor)

– Congenital inner ear malformations (large vestibular aqueduct), perilymph fistula post-trauma

— Pediatric audiogram and MRI brain/IAC mandatory before labeling as Meniere

— Refer to pediatric otolaryngology

— Up to 50% of Meniere patients have migraine

— Treat migraine prophylaxis aggressively — often improves vertigo independent of Meniere therapy

— Diet overlap helpful: both benefit from low-sodium, low-caffeine, trigger avoidance, regular sleep

Pregnancy:

Lactation:

Pediatrics:

Vestibular migraine overlap:

Key distinction: A child with episodic vertigo + normal audiogram likely has benign paroxysmal vertigo of childhood or vestibular migraine, not Meniere — do not start a diuretic.

Complications and Adverse Outcomes

— Progressive permanent SNHL — moderate-to-severe in most patients within 10–20 years

— Persistent tinnitus — often as disabling as vertigo; CBT and sound therapy mainstay

— Bilateral disease in 30–50% over decades — major functional impact

— Aural fullness chronicity independent of attacks

— Chronic disequilibrium between attacks, particularly later stages

— Tumarkin otolithic crisis (drop attacks):

– Sudden falls without warning → fractures, head injury, motor vehicle crashes

– Strong indication to escalate to ablative therapy

— Persistent postural-perceptual dizziness (PPPD): chronic non-spinning dizziness layered onto Meniere; treat with vestibular rehab + SSRI

— Anxiety and depression in 40–60% of patients

— Agoraphobia — fear of attacks in public

— Job loss and disability — Meniere is a leading cause of vestibular disability claims

— Social isolation from communication difficulty

— Diuretics: hypokalemia, hyponatremia, hyperuricemia/gout, dehydration, orthostatic hypotension

— Meclizine/antihistamines: sedation, anticholinergic effects, urinary retention, cognitive impairment

— Benzodiazepines: dependence, falls, cognitive decline

— Intratympanic gentamicin: further hearing loss (~20–30%), persistent imbalance

— Surgery: facial nerve injury, CSF leak, meningitis (rare), hearing loss

— Tympanostomy injection complications: persistent perforation, otitis media

— Unpredictable vertigo + drop attacks → driving restrictions

— Occupational hazards: heights, heavy machinery, commercial driving, piloting

— Disease itself is not fatal, but fall-related injuries in older adults carry significant mortality

Otologic complications:

Vestibular complications:

Psychosocial complications:

Treatment-related complications:

Driving and occupational safety:

Mortality:

CCS pearl: In a CCS-style outpatient case, ordering fall risk assessment, home safety evaluation, and PT/vestibular rehab referral scores points beyond just adjusting medications.

When to Escalate Care — Consults, Inpatient, and Urgent Triage

— First-ever prolonged vertigo episode with any of:

– Age >60 with vascular risk factors

– Central signs on HINTS (normal HIT, direction-changing nystagmus, skew)

– Focal neurologic deficits, diplopia, dysarthria, ataxia out of proportion

– Severe headache, neck pain (vertebral artery dissection)

– Hearing loss + neurologic signs → AICA stroke (lateral pontine syndrome)

— Intractable vomiting with dehydration, electrolyte derangement, inability to tolerate PO

— Suspected acute labyrinthitis with meningeal signs — needs LP, IV antibiotics

— Otolaryngology/neurotology for:

– Sudden SNHL (>30 dB across 3 contiguous frequencies in 72 h) — needs steroids within 2 weeks

– Refractory attacks despite optimal medical therapy at 3–6 months

– Diagnostic uncertainty

– Consideration of intratympanic therapy or surgery

— Neurology for:

– Suspected vestibular migraine or coexisting migraine needing prophylaxis

– Atypical features

— Audiology for serial audiograms and hearing aid evaluation

— Vestibular physical therapy for rehab between attacks

— Comorbid anxiety/depression, agoraphobia, PPPD

— Audiogram within 14 days

— High-dose oral prednisone (e.g., 60 mg × 7–14 days, taper) ± intratympanic dexamethasone salvage

— MRI with gadolinium of IACs to rule out vestibular schwannoma

— FMLA paperwork, workplace accommodation letters

— Vocational rehabilitation referral if job at risk

Immediate ED/inpatient escalation:

Urgent (within days) outpatient referrals:

Mental health referral:

Sudden sensorineural hearing loss workup:

Disability and accommodation:

Step 3 management: Treat sudden SNHL as an otologic emergency — initiate oral steroids within 72 hours for maximum recovery chance and refer to ENT same day, even if Meniere is the suspected underlying diagnosis.

Key Differentials — Other Vestibular and Otologic Causes

— Most common Meniere mimic and most commonly missed alternative diagnosis

— Episodes 5 min – 72 h, often with photophobia, phonophobia, headache, visual aura

— Audiogram typically normal; if hearing loss, doesn't fluctuate in low frequencies

— Treat with migraine prophylaxis

— Brief (<1 min) positional vertigo triggered by head movement

— Positive Dix-Hallpike with torsional upbeating nystagmus

— No hearing loss, no tinnitus, no aural fullness

— Treated with Epley/canalith repositioning

— Single prolonged episode (days) of severe vertigo

— No hearing loss (distinguishes from labyrinthitis)

— Often post-viral; recovery over weeks with vestibular rehab

— Vertigo + acute hearing loss + tinnitus, often post-viral or bacterial (from otitis)

— Usually monophasic unlike recurrent Meniere

— Asymmetric SNHL, progressive (not fluctuating), with unilateral tinnitus

— Imbalance more than spinning vertigo

— MRI IAC with gadolinium diagnostic

— Sound/pressure-induced vertigo (Tullio phenomenon), autophony, pulsatile tinnitus

— Enhanced VEMP with low threshold; CT temporal bone diagnostic

— Post-trauma, post-barotrauma, post-surgery

— Positive fistula test

— Rapidly progressive bilateral SNHL over weeks to months

— Responds to steroids; check ANA, ESR

— Mimics Meniere precisely; check RPR/FTA-ABS in every workup

— Interstitial keratitis + audiovestibular dysfunction; young adults

Vestibular migraine:

Benign paroxysmal positional vertigo (BPPV):

Vestibular neuritis:

Labyrinthitis:

Vestibular schwannoma (acoustic neuroma):

Superior semicircular canal dehiscence:

Perilymph fistula:

Autoimmune inner ear disease:

Otosyphilis:

Cogan syndrome:

Board pearl: Bilateral simultaneous Meniere-like symptoms = think autoimmune inner ear disease or otosyphilis until proven otherwise — order ANA, ESR, RPR/FTA-ABS.

Key Differentials — Non-Otologic and Systemic Causes

— Sudden persistent vertigo + neurologic signs

— AICA stroke uniquely causes vertigo + hearing loss + facial weakness (mimics Meniere acutely)

— PICA stroke: vertigo + ataxia + Horner + dysphagia (Wallenberg)

— HINTS exam, MRI brain

— Episodic vertigo + diplopia, dysarthria, drop attacks in elderly vasculopaths

— MRA or CTA

— Young adult with vertigo + INO, optic neuritis, other CNS lesions

— MRI brain with periventricular lesions

— Lightheadedness on standing, not spinning vertigo

— Orthostatic vitals diagnostic

— Presyncope, palpitations, LOC — not true vertigo

— ECG, Holter monitor

— Lightheadedness, diaphoresis, hunger; fingerstick glucose

— Ototoxic drugs: aminoglycosides, loop diuretics (high-dose), cisplatin, salicylates (high-dose), vancomycin

— Vestibulotoxic: anticonvulsants at toxic levels, lithium toxicity

— Antihypertensives causing orthostasis

— Dizziness with hyperventilation, no true vertigo

— Frequently comorbid with Meniere — treat both

— Neck pain + imbalance; controversial entity

— Persistent rocking sensation after travel

— Hypothyroidism causes generalized dizziness; check TSH

— Severe anemia causes lightheadedness, not spinning

— Imbalance worse with eyes closed (positive Romberg)

Posterior circulation stroke / TIA:

Vertebrobasilar insufficiency:

Multiple sclerosis:

Orthostatic hypotension / autonomic dysfunction:

Cardiac arrhythmia / syncope:

Hypoglycemia:

Medication-induced:

Anxiety and panic disorder:

Cervicogenic dizziness:

Mal de débarquement syndrome:

Thyroid disease:

Anemia:

Diabetic neuropathy / proprioceptive imbalance:

Key distinction: Vertigo + hearing loss + neurologic deficits is stroke until proven otherwise — Meniere never causes diplopia, dysarthria, or limb weakness. Image urgently.

Secondary Prevention and Long-Term Care Plan

— Sodium <1500–2000 mg/day — refer to dietitian; provide written meal plans, label-reading guidance

— Caffeine <100–200 mg/day

— Alcohol limited or avoided

— Smoking cessation — counsel at every visit

— Consistent sleep and stress management

— Regular aerobic exercise — improves vestibular compensation

— Maintenance diuretic continued indefinitely if effective and tolerated

— Betahistine (if available) continued long-term

— Migraine prophylaxis if overlap

— Rescue meclizine/lorazepam/ondansetron prescription on hand for breakthrough attacks — limited quantity to discourage chronic use

— Hearing aids when SNHL becomes communicatively significant

— CROS/BiCROS aids for unilateral severe loss

— Cochlear implant for bilateral severe-profound loss

— Assistive listening devices, captioned telephones

— Sound therapy, tinnitus retraining therapy

— CBT for tinnitus-related distress

— Avoid silence (use ambient sound, white noise)

— Between attacks, formal vestibular PT improves compensation and reduces chronic imbalance

— Habituation, gaze stabilization, balance retraining exercises

— Annual influenza, pneumococcal, COVID — vestibular viral exacerbations may worsen disease

— Screen annually for anxiety/depression (PHQ-9, GAD-7)

— Refer for therapy or SSRI as needed

— Counsel no driving during an attack and for 24 h after

— Drop attack history → stop driving until controlled; understand state reporting requirements

— Workplace accommodations: avoid heights, ladders, heavy machinery, sole-operator commercial driving

Sustained lifestyle measures (lifelong):

Chronic medications:

Hearing rehabilitation:

Tinnitus management:

Vestibular rehabilitation:

Vaccinations:

Mental health:

Driving safety:

Disability and work:

Step 3 management: Build a written Meniere action plan (analogous to asthma action plan): daily meds, rescue meds, attack triggers, when to call, when to go to ED — improves adherence and reduces unnecessary ED visits.

Follow-Up, Monitoring, and Counseling Cadence

— 2–4 weeks after diagnosis: review symptom diary, check electrolytes if on diuretic, reinforce diet

— 3 months: repeat audiogram, assess attack frequency/severity, adjust therapy

— 6 months: audiogram, decide on escalation to intratympanic therapy if attacks persist

— Annually once stable: audiogram, attack frequency review, electrolytes, BP, screening for anxiety/depression

— Every 3–6 months early in disease; annually once stable

— More frequently after sudden hearing changes or new treatments

— Na, K, Cr, uric acid at 2 weeks, 3 months, then annually

— Watch for hyponatremia in elderly

— Date, duration, severity (0–10), aural symptoms, dietary triggers, sleep, stress, menses

— Use validated tools: Dizziness Handicap Inventory (DHI), Tinnitus Handicap Inventory (THI), AAO-HNS Functional Level Scale

— Discuss high-sodium foods (processed meats, canned soups, restaurant meals, condiments)

— MSG, aged cheeses, alcohol, caffeine

— Hormonal influences — track menstrual cycle association

— Reassess after 6–8 weeks of PT

— Medication adherence and side effects

— Driving and occupational safety

— Fall risk in elderly

— Family planning if young woman (med adjustments before conception)

— Mental health screening

— Hearing aid candidacy reassessment

— Maintain communication loop: primary care ↔ otolaryngology ↔ audiology ↔ vestibular PT ↔ mental health

— Updated medication list across all providers

— Vestibular Disorders Association (VeDA), local support groups

Initial follow-up schedule:

Audiometric monitoring:

Laboratory monitoring (if on diuretic):

Symptom diary tracking:

Vestibular rehab progress:

Counseling topics each visit:

Care coordination:

Patient resources:

CCS pearl: On a CCS case, "schedule follow-up in 2–4 weeks with repeat audiogram and BMP" after starting a diuretic is the high-yield order set — captures both efficacy assessment and medication safety monitoring.

Ethical, Legal, and Patient Safety Considerations

— Intratympanic gentamicin: explicit disclosure of 20–30% risk of further hearing loss and persistent imbalance — document understanding, especially because the patient is choosing to trade hearing for vertigo control

— Labyrinthectomy: total loss of hearing in operated ear; irreversible — discuss cochlear implant candidacy implications

— Use shared decision-making with written materials; verify comprehension (teach-back)

— Many US states have physician reporting requirements for conditions causing episodic incapacitation (e.g., California, Oregon, Pennsylvania, Nevada — confirm local laws)

— Document that you counseled against driving during attacks and for 24 hours after; document patient understanding

— Drop attacks (Tumarkin) → counsel cessation of driving until controlled; consider mandatory report if state requires

— Commercial drivers (CDL): Meniere with active attacks disqualifies under DOT medical standards until controlled

— Pilots (FAA), heavy machinery operators, roofers — counsel and document; assist with accommodations or job change

— Meniere is recognized for SSDI/long-term disability with documentation of frequency/severity using validated scales (AAO-HNS functional level)

— Physician documentation matters; objective audiograms strengthen claims

— Beers criteria — meclizine, benzodiazepines, anticholinergics increase fall and delirium risk

— Perform medication reconciliation each visit

— After ED visit for acute attack, ensure outpatient ENT follow-up within 2 weeks, audiogram scheduled, and rescue prescription provided

— Closed-loop communication: PCP receives discharge summary, follows up within 1 week

— Discontinue thiazides and topiramate preconception — avoid teratogen exposure

— Familial Meniere — discuss risk with first-degree relatives, low-threshold audiogram if symptomatic

— Symptom diary, audiograms, driving counseling, informed consent

Informed consent for procedures:

Driving safety and reporting:

Occupational safety:

Disability claims:

Polypharmacy and elderly safety:

Transitions of care:

Pregnancy planning:

Genetic counseling:

Documentation:

Board pearl: A Step 3 stem with a Meniere patient asking about return to commercial driving expects you to counsel against it, document the conversation, and clarify that DOT regulations require sustained control before recertification — not to simply clear them.

High-Yield Associations and Rapid-Fire Clinical Facts

— Vestibular migraine — normal audiogram

— BPPV — seconds, positional, no hearing loss

— Vestibular neuritis — single prolonged episode, no hearing loss

— Labyrinthitis — single episode + hearing loss

— Vestibular schwannoma — progressive asymmetric SNHL, MRI IAC

— Otosyphilis — RPR/FTA-ABS

— Autoimmune inner ear disease — rapid bilateral SNHL

— AICA stroke — vertigo + hearing loss + facial weakness

Classic tetrad: episodic vertigo (20 min–12 h) + fluctuating low-frequency SNHL + tinnitus + aural fullness

Diagnosis is clinical + audiogram; MRI excludes mimics

Audiogram early: low-frequency SNHL ("upsloping")

Audiogram late: flat or peak-pattern SNHL

Weber lateralizes to UNAFFECTED ear (SNHL)

Rinne positive bilaterally (AC > BC)

Caloric testing: unilateral vestibular weakness on affected side

Lermoyez variant: hearing improves at onset of vertigo (rare)

Tumarkin otolithic crisis: sudden drop attacks without LOC; advanced disease

First-line medical therapy: low-sodium diet + HCTZ/triamterene

Acute attack rescue: meclizine, promethazine/ondansetron, benzodiazepine if severe

Avoid chronic meclizine — blunts central compensation

First-line procedural: intratympanic dexamethasone (hearing-preserving)

For non-serviceable ear: intratympanic gentamicin or labyrinthectomy

Bilateral disease in ~30–50% over decades

AAO-HNS 2015 criteria: definite vs probable Meniere

Triggers: salt, caffeine, alcohol, MSG, stress, poor sleep

Comorbidities: migraine (~50%), anxiety/depression (~50%)

Pediatric Meniere is rare — think vestibular migraine or BPV of childhood

Pregnancy: often improves; avoid thiazides, topiramate, benzos

Mimics to memorize:

Ototoxic drugs: aminoglycosides, cisplatin, loop diuretics (high-dose), salicylates

Sudden SNHL: otologic emergency — high-dose oral steroids within 72 hours

Driving: counsel restrictions; check state physician-reporting law

Key distinction: Episodes lasting seconds = BPPV, 20 min–12 h with hearing loss = Meniere, continuous days = vestibular neuritis or stroke, 5 min–72 h with headache/aura = vestibular migraine.

Board Question Stem Patterns

"A 45-year-old woman has 6 months of recurrent 2-hour episodes of spinning vertigo with nausea, left-ear roaring tinnitus, fullness, and muffled hearing. Audiogram shows low-frequency SNHL on the left."

— Answer: Meniere disease; start low-sodium diet + HCTZ/triamterene; order MRI IAC if asymmetric.

"30-second episodes of vertigo triggered by rolling in bed, normal hearing."

— Answer: BPPV → Dix-Hallpike, Epley maneuver. Not Meniere.

"Recurrent vertigo with photophobia and headache; audiogram normal."

— Answer: Vestibular migraine; migraine prophylaxis.

"Elderly hypertensive smoker with acute persistent vertigo, ataxia, dysarthria, and normal head impulse test."

— Answer: Posterior circulation stroke; MRI brain, stroke pathway. Not Meniere.

"Progressive (not fluctuating) unilateral hearing loss with mild imbalance; tinnitus."

— Answer: MRI IAC with gadolinium → vestibular schwannoma.

"Woke up with profound left-sided hearing loss and tinnitus; vertigo absent."

— Answer: Sudden SNHL — oral prednisone within 72 h, urgent ENT/audiology.

"Long-standing Meniere now with sudden unprovoked falls without LOC."

— Answer: Tumarkin crisis → refer for intratympanic gentamicin or surgical ablation; restrict driving.

"Young woman with bilateral progressive hearing loss over weeks, vertigo."

— Answer: Autoimmune inner ear disease → high-dose steroids; check ANA, ESR. Or otosyphilis → RPR.

"78-year-old on chronic meclizine and lorazepam falls at home."

— Answer: Stop chronic vestibular suppressants, fall risk assessment, vestibular rehab.

"32-year-old with Meniere on HCTZ/triamterene plans pregnancy."

— Answer: Discontinue thiazide preconception; manage with diet and acute meclizine PRN.

"Patient meeting Meniere criteria but audiogram shows asymmetric loss."

— Answer: MRI brain/IAC with gadolinium to exclude vestibular schwannoma.

Stem 1 — Classic presentation:

Stem 2 — Distinguish from BPPV:

Stem 3 — Distinguish from vestibular migraine:

Stem 4 — Stroke vs peripheral:

Stem 5 — Acoustic neuroma:

Stem 6 — Sudden SNHL:

Stem 7 — Drop attacks:

Stem 8 — Bilateral rapid SNHL:

Stem 9 — Medication safety:

Stem 10 — Pregnancy:

Stem 11 — Asymmetric SNHL workup:

CCS pearl: Whenever a Meniere stem opens with "asymmetric" or "unilateral progressive" SNHL, the next order is MRI IAC with contrast — that order alone often scores the diagnostic point.

One-Line Recap

Meniere disease is a clinical diagnosis of recurrent 20-minute-to-12-hour episodes of vertigo with fluctuating low-frequency sensorineural hearing loss, tinnitus, and aural fullness — managed first with low-sodium diet plus a thiazide diuretic, escalated through intratympanic steroids, gentamicin, and finally ablative surgery while preserving hearing as long as possible.

Diagnose by history + audiogram: Episodes 20 min–12 h, fluctuating low-frequency SNHL on the affected side, tinnitus, aural fullness — and rule out mimics (vestibular migraine, BPPV, neuritis, schwannoma, stroke, otosyphilis, autoimmune inner ear disease) with MRI IAC + gadolinium and selective labs.

First-line management is lifestyle: Sodium <1500–2000 mg/day, limit caffeine/alcohol/MSG, stable sleep, stress reduction, symptom diary — then add HCTZ 25 mg/triamterene 37.5 mg daily for maintenance.

Acute attacks: meclizine, antiemetic (ondansetron or promethazine), benzodiazepine if severe — for days, not weeks, to preserve central vestibular compensation.

Escalate when conservative therapy fails: intratympanic dexamethasone (hearing-preserving) → intratympanic gentamicin (if hearing already poor) → labyrinthectomy or vestibular nerve section for refractory disabling disease; cochlear implant for end-stage bilateral hearing loss.

Long-term care is multidisciplinary: PCP + ENT/neurotology + audiology + vestibular PT + mental health; annual audiograms, electrolyte monitoring on diuretics, fall prevention in elderly, driving counseling and state-mandated reporting where applicable.

Step 3 management: Build a written Meniere action plan, schedule 2–4 week and 3-month follow-up after diagnosis, treat sudden SNHL as a 72-hour emergency with oral steroids, and adjust regimens preconception in women of reproductive age — these are the ambulatory anchors that win Step 3 stems.
