Acute laryngitis and chronic hoarseness workup

Clinical Overview and When to Suspect Laryngitis/Hoarseness

Acute (<2 weeks): Usually viral URI, vocal abuse (shouting, singing), or post-extubation. Self-limited, supportive care only.

Chronic (>2–4 weeks): Requires laryngoscopy. Broad differential including reflux (LPR), smoking-related Reinke edema, vocal nodules/polyps, neurogenic causes (RLN palsy), malignancy, fungal (post-inhaled steroid), and systemic (hypothyroidism, GPA, sarcoid, RA cricoarytenoid arthritis).

— Hoarseness >3 weeks in a smoker >40

— Dysphagia, odynophagia, otalgia (referred via CN X), neck mass, hemoptysis

— Stridor, weight loss, prior head/neck radiation

Board pearl: Persistent hoarseness >2 weeks in any adult — especially smoker — mandates flexible laryngoscopy referral to ENT, regardless of how benign the history sounds. This is one of the most tested ambulatory decisions on Step 3 and the threshold to refer is intentionally low because early laryngeal cancer is curable (>90% 5-yr).

Definition: Dysphonia = any altered voice quality, pitch, loudness, or vocal effort; hoarseness is the lay descriptor patients use. Laryngitis = inflammation of the larynx producing dysphonia ± odynophonia, cough, throat clearing.
Acute vs chronic — the central Step 3 fork:
Epidemiology: Lifetime prevalence ~30%; peaks in teachers, singers, clergy, call-center workers (occupational voice users). Smoking + alcohol = synergistic risk for laryngeal SCC.
When to suspect malignancy ("red flag" hoarseness):
Outpatient framing (Family Medicine voice): Most acute cases need reassurance + voice rest, NOT antibiotics. The Step 3 trap is prescribing azithromycin for a viral laryngitis — AAO-HNS explicitly recommends against routine antibiotics.
Why the larynx matters systemically: The recurrent laryngeal nerve loops around the aortic arch (left) and subclavian (right); any mediastinal or apical pathology (lung CA, aortic aneurysm, mediastinal LAD, thyroid mass) can present as isolated hoarseness.
Solid White Background
Presentation Patterns and Key History

Hypothyroidism: Low, hoarse voice + fatigue, cold intolerance, weight gain

GPA (Wegener): Subglottic stenosis, saddle nose, hemoptysis, sinusitis

Sarcoid: Supraglottic edema, lupus pernio, hilar LAD

RA: Cricoarytenoid arthritis → morning hoarseness + known RA

Key distinction: Hoarseness that fluctuates with voice use → benign mucosal lesion (nodule/polyp/cyst). Hoarseness that is constant and progressive → think neurogenic palsy, mass, or fixation. Hoarseness that is worse in the morning → LPR. This temporal pattern alone reorganizes the differential before laryngoscopy.

Acute viral laryngitis: 1–2 day prodrome of rhinorrhea, sore throat, low-grade fever, then dysphonia or aphonia lasting 3–7 days. Cough, mild odynophagia. No drooling, no stridor in adults — those suggest supraglottitis/epiglottitis.
Vocal misuse/abuse: Acute onset after a concert, sports event, prolonged talking; recurrent pattern in singers and teachers. Worse with continued voice use.
Laryngopharyngeal reflux (LPR): Morning hoarseness, globus sensation, chronic throat clearing, postnasal drip sensation, chronic cough. Heartburn is absent in >50% (silent reflux). Symptoms worse after late meals, supine.
Vocal nodules/polyps: Chronic, intermittent hoarseness in heavy voice users; voice "breaks" with high notes; worsens through the day.
Reinke edema (smoker's polyposis): Low-pitched, gravelly voice in middle-aged female smoker — classic stem.
Recurrent laryngeal nerve palsy: Breathy voice, weak cough ("bovine cough"), aspiration with thin liquids. Ask about recent thyroid surgery, anterior cervical spine surgery, CABG, lung CA history.
Systemic clues:
Medication history: Inhaled corticosteroids (candidiasis, myopathy of TA muscle), ACE inhibitors (cough irritation), antipsychotics/antihistamines (laryngeal dryness), bisphosphonates (esophagitis mimicking LPR).
Solid White Background
Physical Exam Findings (and Airway Assessment)

Breathy: Glottic gap → vocal cord paralysis, atrophy (presbylarynx), large polyp

Strained/strangled: Spasmodic dysphonia (adductor type), muscle tension dysphonia

Rough/raspy: Mass lesion, edema, Reinke

Diplophonic (two pitches): Asymmetric cord vibration → unilateral lesion

Aphonia with normal cough: Functional/psychogenic dysphonia (intact reflexive phonation)

— Inspect oropharynx for thrush (ICS use, immunocompromise), tonsillar asymmetry

— Palpate neck for thyroid nodules/goiter, cervical/supraclavicular LAD, laryngeal crepitus on rocking (loss may suggest postcricoid mass)

— Cranial nerves IX, X, XI, XII — palatal elevation, gag, shoulder shrug, tongue protrusion (skull-base lesions)

Step 3 management: In the outpatient stem, a hoarse patient with new Horner syndrome or supraclavicular adenopathy gets urgent CT chest with contrast before (or alongside) ENT referral — the larynx exam may be normal because the lesion is along the RLN course, not in the larynx itself. Ordering laryngoscopy alone and stopping there is the trap answer.

General appearance and airway first: In any acute hoarseness with stridor, tripoding, drooling, or muffled "hot potato" voice, stop the routine workup — this is supraglottitis until proven otherwise. Call anesthesia/ENT for controlled airway evaluation; do NOT lie the patient flat or attempt blind oral exam in children.
Voice characterization (a real exam skill):
Head & neck exam:
Pulmonary/cardiac: Wheeze localized to neck = upper airway. Look for clubbing, supraclavicular node (Virchow), Horner syndrome (apical lung tumor compressing sympathetic chain + RLN — Pancoast).
Skin/MSK: Saddle nose (GPA), butterfly rash (SLE — rare laryngeal involvement), synovitis (RA).
Solid White Background
Diagnostic Workup — Initial Office Evaluation

— No labs, no imaging, no scope

— Symptomatic care; reassess at 2 weeks

TSH if features of hypothyroidism or chronic unexplained hoarseness

CBC if systemic symptoms or suspected infection

ANCA, ANA, RF/anti-CCP, ACE level only when vasculitis/autoimmune suspected

HIV if oral candidiasis or atypical infections

CT neck + chest with contrast: Indicated when laryngoscopy shows vocal cord paralysis (to trace the entire RLN from skull base to mediastinum), or when malignancy/mass suspected

MRI brain/skull base: If high vagal lesion (paralysis + other CN deficits, palatal weakness)

Barium swallow/modified barium swallow: When aspiration or Zenker diverticulum suspected

Stroboscopy (videostroboscopy): Slows mucosal wave for subtle lesion detection — done by ENT/SLP, gold standard for benign mucosal pathology

Acoustic analysis and Voice Handicap Index (VHI-10) for severity/follow-up

Board pearl: AAO-HNS explicitly states clinicians should NOT prescribe antireflux medications empirically for isolated dysphonia without GERD symptoms and without prior laryngoscopy. The empirical PPI trial in chronic hoarseness is a tested wrong answer.

The cornerstone investigation: flexible fiberoptic laryngoscopy. Indicated for any hoarseness ≥2 weeks (AAO-HNS 2018 guideline), or sooner if red flags. Performed in clinic by ENT (or trained PCP). Visualizes true cords, false cords, arytenoids, epiglottis, vallecula, pyriform sinuses, post-cricoid area.
What you can defer initially in clear-cut acute viral laryngitis (<2 wks, URI context, no red flags):
Labs — selectively, not routinely:
Imaging:
Adjuncts:
What NOT to order reflexively: Plain neck x-ray (low yield), throat culture (acute laryngitis is viral), empiric PPI trial as a substitute for laryngoscopy when symptoms persist beyond 2 weeks.
Solid White Background
Diagnostic Workup — Advanced and Confirmatory Studies

— Definitive evaluation when an office scope reveals a suspicious lesion (leukoplakia, ulcer, mass, asymmetric fixation)

— Allows biopsy, excision of nodules/polyps/cysts, sampling for AFB and fungal stains

— Suspected SCC → H&E + HPV/p16 (esp. supraglottic/oropharyngeal extension)

— Granulomatous lesions → AFB, GMS/PAS (TB, histoplasma, blastomyces, candida), tissue culture

— Vasculitis suspicion → adequate tissue for vasculitis pathology; pair with ANCA serology

— Absent mucosal wave over a cord segment = scar or invasion (concerning for malignancy)

— Phase asymmetry without lesion = paresis

— Distinguishes vocal fold paralysis (denervation, fibrillations) from mechanical fixation (cricoarytenoid arthritis, scar, posterior glottic stenosis)

— Prognostic for recovery in idiopathic RLN palsy at 4–6 months

— Reserved for LPR cases refractory to PPI + lifestyle who are being considered for fundoplication, or to confirm reflux when diagnosis is equivocal

Speech-language pathology (SLP): Diagnostic + therapeutic — voice therapy is first-line for nodules, muscle tension dysphonia, presbylarynx

Pulmonology: Suspected subglottic stenosis, GPA, sarcoid

Gastroenterology: Refractory LPR, dysphagia

Neurology: Spasmodic dysphonia, essential tremor of voice, parkinsonian dysphonia

Key distinction: Vocal fold paralysis (neural injury — flaccid, foreshortened cord, atrophy on EMG) vs vocal fold fixation (mechanical — cricoarytenoid joint, scar, posterior glottic stenosis — normal EMG). Surgical planning differs substantially; both look immobile on routine scope, hence the role of laryngeal EMG before any medialization procedure.

Solid White Background
Risk Stratification and Management Logic

<2 weeks + viral context + no red flags: Symptomatic management, no workup, reassess

≥2 weeks OR any red flag at any time: Laryngoscopy

— Smoker >40, tobacco/alcohol use

— Hemoptysis, otalgia, dysphagia, odynophagia, weight loss

— Neck mass, supraclavicular adenopathy

— Stridor, dyspnea

— Recent neck/thoracic surgery (RLN injury)

— Hoarseness in a professional voice user impairing livelihood

— Immunocompromise (HIV, transplant, chronic steroids)

— History of head/neck cancer or radiation

Normal larynx + reflux symptoms: 8–12 week trial of lifestyle + PPI BID; reassess

Benign mucosal lesion (nodule, polyp, cyst, Reinke): SLP voice therapy first; phonomicrosurgery if persistent

Vocal fold paralysis: Image RLN course (CT skull base to mediastinum); voice therapy; injection medialization if symptomatic; framework surgery if persistent >9–12 months

Leukoplakia/suspicious lesion: Direct laryngoscopy + biopsy under GA

Granulomas (contact/intubation): Voice rest, PPI, treat cough; rarely excise

Functional/psychogenic: SLP, address triggers

Step 3 management: In the ambulatory setting, the correct sequence for an adult presenting at week 3 of hoarseness — even one who feels otherwise fine — is (1) flexible laryngoscopy referral, (2) targeted workup based on findings, (3) NOT empiric PPI, NOT empiric antibiotic, NOT "wait another month." Delayed referral is the most common deviation from guideline care and a frequent Step 3 vignette pitfall.

Stratify by duration first:
Red flags mandating expedited (≤2 week) ENT referral:
Once laryngoscopy is done — management branches:
Counsel on natural history: Acute viral laryngitis resolves in 7–10 days; voice rest (not whisper — whisper increases strain) accelerates recovery.
Solid White Background
Pharmacotherapy — Evidence-Based Drug Regimens

No antibiotics (AAO-HNS strong recommendation against). Even if bacterial superinfection is suspected, evidence shows no benefit on dysphonia outcomes.

— Analgesia: acetaminophen or NSAIDs

— Humidified air, hydration, voice rest, avoid whispering and throat clearing

— Lozenges with menthol/benzocaine for symptomatic relief

Brief (3–5 day) oral steroids (prednisone 40–60 mg) for professional voice users with urgent performance commitments, severe edema on scope, or supraglottitis (with airway monitoring)

— Not routine for community-acquired acute laryngitis

PPI BID (omeprazole 20 mg, esomeprazole 20 mg, pantoprazole 40 mg) 30–60 min before breakfast and dinner × 8–12 weeks, then reassess

— H2 blocker at bedtime (famotidine 20–40 mg) as adjunct if nocturnal breakthrough

— Alginates (Gaviscon Advance) post-meal and bedtime — useful adjunct

Lifestyle is co-equal: weight loss, elevate head of bed, avoid meals 3 h before sleep, limit alcohol/caffeine/tobacco/chocolate/peppermint

— Deprescribe PPI if no benefit at 12 weeks — chronic PPI risks (C. difficile, fracture, hypomagnesemia, B12 deficiency, CKD, pneumonia) are testable

— Switch to MDI + spacer, rinse mouth after dosing, treat candidiasis with nystatin swish-and-swallow or oral fluconazole

— Lowest effective ICS dose; consider DPI swap

Board pearl: The classic wrong-answer cluster in acute laryngitis stems: amoxicillin, azithromycin, dexamethasone, and empiric PPI. The right answer in pure viral acute laryngitis is supportive care + voice rest + reassess in 2 weeks.

Acute viral laryngitis:
Corticosteroids — narrow indications only:
Laryngopharyngeal reflux:
Inhaled steroid-associated dysphonia:
Fungal laryngitis: Oral fluconazole 200 mg load then 100 mg daily × 3 weeks (post-ICS, diabetic, immunocompromised)
Spasmodic dysphonia: Botulinum toxin injection to thyroarytenoid (adductor type) by ENT q3–4 months — first-line therapy.
Solid White Background
Procedural and Surgical Management

Injection laryngoplasty (medialization): Temporary (collagen, hyaluronic acid, carboxymethylcellulose — 1–3 months) or longer-lasting (calcium hydroxyapatite — 12–18 months). Indicated for symptomatic unilateral vocal cord paralysis to restore glottic closure and improve voice/swallow/cough.

In-office KTP/PDL laser: For dysplasia, papillomatosis (recurrent respiratory papillomatosis — HPV 6/11), vascular lesions.

Botox injection: Spasmodic dysphonia, vocal tremor.

Microsuspension direct laryngoscopy with phonomicrosurgery: Removal of polyps, cysts, Reinke edema (cordotomy + suction), papillomas. Cold instruments preferred over CO2 laser for benign lesions to preserve mucosal wave.

Laryngeal framework surgery (medialization thyroplasty, Isshiki type I): Permanent silastic or Gore-Tex implant via thyroid cartilage window — for persistent unilateral paralysis after observation period (often 9–12 months from onset to allow spontaneous recovery), or earlier if known nerve transection.

Arytenoid adduction: Added when large posterior glottic gap persists.

Reinnervation (ansa cervicalis-to-RLN): Younger patients with cut nerve, restores tone and bulk.

Acute supraglottitis/epiglottitis with stridor: Awake fiberoptic intubation in OR with surgical airway backup. Cefotaxime/ceftriaxone + vancomycin; dexamethasone.

Bilateral vocal fold paralysis with airway compromise: Tracheostomy; later cordotomy or arytenoidectomy to enlarge airway (trading voice for airway).

CCS pearl: If your CCS case is a patient with stridor and muffled voice after recent thyroidectomy, don't order a CT — order STAT ENT consult and flexible laryngoscopy at bedside, prepare OR for possible reintubation/tracheostomy. Bilateral RLN injury is a post-thyroidectomy emergency on the order of an hour, not a day.

Office-based procedures (ENT):
Operating room procedures:
Cancer-directed surgery: Transoral laser microsurgery, transoral robotic surgery (TORS), partial or total laryngectomy depending on T stage; chemoradiation organ-preservation protocols for T2–T3.
Airway emergencies:
Solid White Background
Special Populations — Elderly, Renal, and Hepatic Impairment

— Bilateral bowing of cords, spindle-shaped glottic gap on phonation

— Symptoms: breathy weak voice, vocal fatigue, reduced loudness, aspiration with thin liquids

Voice therapy is first-line — evidence-based (LSVT-LOUD program borrowed from Parkinson protocols)

— Injection augmentation or medialization if therapy insufficient

— Higher prevalence of laryngeal SCC — lower threshold for biopsy of leukoplakia

— Parkinson disease: hypokinetic dysarthria with reduced loudness, monotone — refer neurology

— Essential tremor of voice — propranolol or primidone may help

— Stroke: sudden dysphonia + dysphagia → urgent neuro workup

— Anticholinergics (TCAs, oxybutynin, 1st-gen antihistamines) → mucosal dryness → vocal fatigue

— Diuretics → dehydration → dryness

— Inhaled steroids → candidiasis, TA myopathy

— ACE inhibitors → cough → mechanical phonotrauma; consider switching to ARB

— Bisphosphonates → reflux esophagitis mimicking LPR

PPIs: No dose adjustment needed for renal function, but observational link to AKI/CKD progression — use shortest effective course

Famotidine: Reduce dose if CrCl <50; dose-related confusion in elderly with renal impairment

Fluconazole: Reduce dose 50% if CrCl <50

— Avoid NSAIDs if CKD stage ≥3

Fluconazole: Hepatotoxicity — monitor LFTs in prolonged courses

Acetaminophen: Cap at 2 g/day in advanced liver disease

— Most PPIs metabolized hepatically (omeprazole CYP2C19) — lower dose in severe cirrhosis

Step 3 management: In an elderly patient with chronic breathy voice, mild aspiration, and bilateral cord bowing on scope, the first intervention is referral to SLP for voice therapy, NOT immediate injection augmentation. Procedures are reserved for therapy non-responders, and trying therapy first is both guideline-concordant and the test answer.

Solid White Background
Special Populations — Pregnancy, Pediatrics, and Performers

— Hormonal vocal fold edema and increased reflux are common; voice changes peak in 3rd trimester

Acute laryngitis treatment: Supportive only. Acetaminophen is preferred analgesic. Avoid NSAIDs especially after 20 weeks (oligohydramnios) and after 30 weeks (premature ductal closure)

PPI/H2 if reflux: Famotidine and most PPIs (omeprazole, pantoprazole) are considered acceptable in pregnancy; antacids (calcium carbonate) first-line; avoid magnesium trisilicate and sodium bicarbonate

— Defer elective laryngeal surgery to postpartum if possible

Fluconazole: Avoid high-dose in 1st trimester (teratogenicity); topical antifungals preferred

— Acute laryngitis in young child rare in isolation — think croup (parainfluenza, barking cough, inspiratory stridor, age 6 mo–6 yr). Treat with dexamethasone 0.6 mg/kg once; nebulized racemic epinephrine if stridor at rest

Epiglottitis (rare post-Hib vaccine): high fever, drooling, tripoding, muffled voice — OR airway management

Recurrent respiratory papillomatosis (RRP): HPV 6/11, vertical transmission; progressive hoarseness in toddler/young child; serial laser excision; HPV vaccination reduces incidence

Vocal nodules: Common in school-age children, especially boys; voice therapy is mainstay — do not operate on pediatric nodules, they often resolve at puberty

— Lower threshold for laryngoscopy, even at <2 weeks, especially before performances

— Voice rest, hydration, humidification core

— Short-course oral steroids selectively for urgent performance commitments (acknowledge ethics — "performance enhancement" should not mask serious pathology)

— Refer to dedicated voice clinics; coordinate with vocal coach + SLP + ENT

Board pearl: Hoarseness with stridor in a child >3 years who is unvaccinated against Hib and toxic-appearing → epiglottitis until proven otherwise — keep the child calm with caregiver, avoid IV/exam, transport to OR for controlled airway. Lateral neck XR ("thumbprint sign") only if airway stable and child cooperative.

Complications and Adverse Outcomes

Laryngeal SCC: Delay in diagnosis upstages disease — T1 glottic SCC has >90% 5-year survival; T4 drops below 50%. Voice quality and survival both at stake.

Vocal cord paralysis complications: Aspiration pneumonia (incompetent glottic closure), weight loss from dysphagia, ineffective cough

Bilateral RLN palsy: Acute airway obstruction post-thyroidectomy; subacute presentation with exertional stridor in median position

Chronic LPR: Subglottic stenosis, granulomas, contact ulcers, Barrett esophagus risk (when concomitant GERD), and rarely esophageal adenocarcinoma

Untreated benign lesions: Polyp → permanent dysphonia; Reinke edema → airway narrowing in advanced cases

Recurrent respiratory papillomatosis: Airway obstruction; rare malignant transformation

PPI long-term: C. difficile colitis, community-acquired pneumonia, hypomagnesemia, B12 deficiency, hip/spine fracture risk, CKD progression, rebound acid hypersecretion on withdrawal

Systemic corticosteroids: Hyperglycemia, hypertension, mood lability, insomnia, AVN with repeated courses

Injection laryngoplasty: Overinjection → strained voice, dysphagia; migration; rare airway compromise

Thyroplasty: Implant extrusion, infection, undercorrection/overcorrection, airway edema

Microlaryngoscopy: Dental injury (>1% — informed consent point), tongue paresthesia from tongue base pressure, postoperative dysphonia from mucosal disruption

Tracheostomy (for bilateral palsy): Stomal infection, tracheal stenosis, accidental decannulation, loss of natural voice

— Job loss in professional voice users; depression, anxiety; social isolation

— Voice Handicap Index (VHI-10) ≥11 = clinically significant impact

Key distinction: Aspiration in unilateral cord paralysis is typically with thin liquids and managed with diet modification + voice therapy + injection augmentation; aspiration in bilateral palsy or high vagal lesion is more severe and may require gastrostomy and tracheostomy.

When to Escalate Care

— Stridor at rest, tripoding, drooling, "hot potato" voice → supraglottitis/epiglottitis

— Post-thyroidectomy stridor or aphonia → bilateral RLN palsy or expanding neck hematoma (look for tense neck swelling — open wound at bedside)

— Acute angioedema involving larynx (ACE inhibitor, hereditary) → epinephrine IM, airway, C1 esterase replacement or icatibant for HAE

— Anaphylaxis with laryngeal edema

— Caustic ingestion with hoarseness

— Hoarseness ≥2 weeks

— Suspected malignancy (neck mass, smoker, hemoptysis, otalgia, dysphagia)

— New vocal cord paralysis without obvious explanation

— Suspected RRP in child

— Professional voice user with significant impairment

Speech-language pathology: Nearly all benign mucosal lesions, muscle tension dysphonia, presbylarynx, post-stroke dysphonia

Pulmonology: Suspected subglottic stenosis, GPA, sarcoid, chronic cough

Gastroenterology: Refractory LPR/GERD, dysphagia

Oncology/radiation oncology: Confirmed laryngeal cancer — multidisciplinary tumor board

Neurology: Spasmodic dysphonia, parkinsonian voice, ALS suspicion (fasciculations, dysarthria, weakness)

Endocrinology: Hypothyroid-related voice change refractory to euthyroid state

— Airway concern (any stridor, accessory muscle use)

— Inability to manage secretions/aspiration with weight loss

— Severe systemic vasculitis requiring induction therapy

CCS pearl: When a CCS case features a hoarse patient with supraclavicular adenopathy, order flexible laryngoscopy + CT neck and chest with contrast + ENT consult in the same advance-clock block, then move forward. Sequential ordering wastes simulated time and downgrades efficiency scoring. Combine workup steps when the clinical picture demands parallel evaluation.

Key Differentials — Same Category (Laryngeal/Airway Causes)

Key distinction: Nodules are bilateral and symmetric; polyps and cysts are typically unilateral. Nodules respond to voice therapy alone; polyps and cysts usually require phonomicrosurgery. The unilateral-vs-bilateral cue on a scope image is a frequent Step 3 visual identifier.

Acute laryngitis (viral): Self-limited, URI context, normal scope or mild diffuse erythema/edema.
Acute bacterial laryngitis: Rare; consider in unvaccinated, immunocompromised. Group A strep, M. catarrhalis, H. influenzae. Treatment shifts toward antibiotics only if pharyngitis/supraglottitis confirmed.
Supraglottitis/epiglottitis: Airway emergency; cherry-red epiglottis on lateral neck or scope (controlled setting).
Croup (laryngotracheobronchitis): Pediatric, parainfluenza, barking cough, stridor.
Vocal nodules: Bilateral, symmetric, at junction of anterior 1/3 and posterior 2/3 of cord — phonotrauma; voice therapy.
Vocal polyp: Usually unilateral, pedunculated; acute phonotrauma; often needs excision.
Vocal cyst: Subepithelial mucus-retention cyst; needs microflap excision.
Reinke edema: Bilateral, gelatinous, diffuse cord swelling; smokers; smoking cessation + microsurgery.
Contact granuloma: Posterior cord/vocal process; reflux, intubation, throat clearing.
Laryngeal papillomatosis (RRP): HPV 6/11; recurrent excisions; bevacizumab adjunct in adults.
Leukoplakia/dysplasia/SCC: White plaque, ulcer, mass; biopsy.
Vocal cord paralysis/paresis: Unilateral more common (left RLN longest course); breathy voice; image RLN tract.
Spasmodic dysphonia: Strained-strangled (adductor) or breathy/effortful (abductor); botulinum toxin.
Muscle tension dysphonia: Hyperfunctional pattern; SLP first-line.
Functional/psychogenic aphonia: Sudden complete aphonia with normal cough/laughter; SLP and reassurance.
Subglottic stenosis: Idiopathic (women), post-intubation, GPA-related; biphasic stridor, dyspnea; dilation/laser.
Laryngeal trauma: Blunt neck trauma, hanging injury — emergent.
Inhalation injury: Smoke, caustic, thermal — airway secured early.
Fungal laryngitis: Candida (post-ICS), histoplasma (endemic regions), blastomyces.

Key Differentials — Other-Category Causes

— Stroke (brainstem, particularly lateral medullary/Wallenberg) — ipsilateral cord paralysis, palatal weakness, Horner, ataxia

— Parkinson disease — hypophonic monotone, festinating speech; LSVT-LOUD

— Multiple sclerosis — scanning speech, intention tremor of voice

— Myasthenia gravis — fatigable dysphonia worse at end of day

— ALS — progressive bulbar weakness, fasciculations, mixed UMN/LMN

— Essential tremor of voice

— Spasmodic dysphonia (focal dystonia)

— Hypothyroidism — myxedematous infiltration of cords → low, hoarse voice

— Acromegaly — soft tissue hypertrophy

— RA — cricoarytenoid arthritis, morning hoarseness

— GPA — subglottic stenosis, saddle nose

— Sarcoidosis — supraglottic edema, "turban epiglottis"

— Relapsing polychondritis — auricular and laryngeal cartilage inflammation

— Amyloidosis — submucosal deposition

— SLE — rare; cricoarytenoiditis

— Lung apex (Pancoast) → left or right RLN compression

— Thyroid carcinoma with extracapsular extension

— Mediastinal lymphoma, esophageal cancer, aortic aneurysm

— Skull base tumors (glomus jugulare, schwannoma) → high vagal palsy

— Post-thyroidectomy RLN injury (~1% unilateral, <0.5% bilateral)

— Post-anterior cervical discectomy/fusion — retraction injury

— Post-CABG (left RLN stretch)

— Post-intubation granuloma, ulcer, posterior glottic stenosis

— Inhaled corticosteroid-induced dysphonia, candidiasis, myopathy

— Radiation-induced fibrosis/laryngeal edema

Board pearl: Isolated left vocal cord paralysis in a 60-year-old smoker is lung cancer until proven otherwise — image the entire RLN course (skull base to aortopulmonary window) with CT chest with contrast, even if the chest exam and CXR are unremarkable. The recurrent laryngeal nerve dips into the mediastinum, and small AP-window nodes will be missed by plain film.

Secondary Prevention and Long-Term Plan

Smoking cessation: Single highest-yield intervention — reduces laryngeal SCC, Reinke edema, chronic laryngitis, LPR; offer pharmacotherapy (varenicline, bupropion, NRT) and behavioral support; quitlines (1-800-QUIT-NOW)

Alcohol moderation: Synergistic with tobacco for SCC

Hydration: ≥1.5–2 L water daily for mucosal lubrication

Humidification: Especially in heated/air-conditioned environments

Vocal hygiene: Avoid throat clearing (use silent swallow), avoid whispering during recovery, warm up the voice before extended use, minimize screaming, manage allergies

— Sustained weight loss if BMI elevated (most powerful intervention)

— Elevate head of bed 6–8 inches (blocks under bedposts; pillows ineffective)

— No food/drink within 3 hours of bedtime

— Limit trigger foods (chocolate, peppermint, citrus, tomato, caffeine, alcohol, fatty/fried foods)

— Step down PPI to lowest effective dose; consider H2RA or on-demand therapy

— Amplification devices for teachers

— Headset microphones

— Voice rest blocks built into work schedule

— Annual ENT/SLP check-ins

— Surveillance scope and imaging per NCCN: q1–3 mo year 1, q2–6 mo year 2, q4–8 mo years 3–5, then annually

— Smoking and alcohol cessation reduce second primary risk

— TSH q6–12 mo if neck radiation (hypothyroidism in 30–50%)

— Swallowing rehabilitation, voice prosthesis care (post-laryngectomy)

— HPV vaccination counseling for prevention in eligible patients

Step 3 management: Every patient with hoarseness who smokes leaves the office with (1) a brief tobacco cessation counseling note (5 A's), (2) pharmacotherapy offered, and (3) follow-up scheduled. Missing the cessation intervention is a deduction in both real-world quality metrics (MIPS) and on test items emphasizing comprehensive ambulatory care.

Solid White Background
Follow-Up, Monitoring, and Counseling

— Reassess at 2 weeks (in person or telehealth)

— If unresolved at 2 weeks → ENT referral

— Document smoking status, voice use, reflux symptoms

— Voice therapy course: 4–8 sessions over 2–3 months

— SLP outcome measures: VHI-10, GRBAS scale, acoustic parameters

— Repeat scope at end of therapy course; advance to surgery if persistent symptomatic lesion

— Reassess at 8–12 weeks with Reflux Symptom Index (RSI)

— If improved: continue 8–12 more weeks then step down

— If unimproved: laryngoscopy if not already done, pH/impedance probe, consider GI

— Observation period 6–12 months for spontaneous recovery (idiopathic, post-viral)

— Interim injection medialization for symptomatic patients

— Repeat scope and laryngeal EMG at 4–6 months for prognosis

— Permanent surgery (thyroplasty) if no recovery by 9–12 months

— Strict voice rest 3–7 days

— Follow-up scope at 2 and 6 weeks

— Resume voice therapy after mucosal healing

— Long-term PPI: serum magnesium annually, B12 every 1–2 years, bone density per age/risk, renal function annually

— Inhaled steroids: oral exam, voice check at each visit

— Botulinum toxin: voice diary, retreatment q3–4 months

— Natural history and timeline of recovery

— When to return (worsening, stridor, dysphagia, hemoptysis)

— Voice hygiene handout

— Smoking/alcohol cessation

— Reflux precautions

CCS pearl: For a CCS chronic hoarseness case, schedule the follow-up visit before advancing the clock past the diagnostic step — "Schedule clinic follow-up in 2 weeks" is a graded action. Skipping follow-up scheduling on outpatient cases is a common point-loss item that has nothing to do with diagnostic accuracy.

Ethical, Legal, and Patient Safety Considerations

— Microlaryngoscopy: explicitly discuss dental injury (1–6%), tongue numbness/dysgeusia, postoperative dysphonia, airway risk, need for repeat procedure

— Thyroplasty: voice may be worse before better; implant infection/extrusion; rare airway edema requiring observation

— Botulinum toxin: temporary breathy voice and dysphagia for thin liquids 1–2 weeks post-injection — counsel choking risk

— Post-thyroidectomy RLN injury must be disclosed promptly; the surgeon is obligated to inform, document, and arrange ENT evaluation. Concealment violates ethical and legal standards

— Sentinel event reporting if airway compromise requires unplanned tracheostomy

— Teachers, performers, broadcasters with chronic dysphonia may qualify for FMLA, ADA accommodations (amplification, modified duties), or workers' compensation when occupational

— Document objective measures (VHI-10, stroboscopy) for disability claims

— Discharge after thyroid/parathyroid/cervical spine/CABG surgery should include explicit instructions to seek care for new hoarseness, stridor, or aspiration — and the discharge summary should communicate any documented RLN risk to the PCP

— Pending biopsy results from microlaryngoscopy must have a closed-loop follow-up system — failure to communicate a positive biopsy is a leading source of malpractice claims in laryngology

— Screen for intimate partner violence in suspicious laryngeal/neck trauma (strangulation injuries — petechiae, voice change, neck bruising). Document the exam; strangulation is a high-risk marker for future homicide; offer safety planning and resources (National DV Hotline 1-800-799-7233). Mandatory reporting laws vary by state but child and elder abuse reporting is universal when injury is suspected

— Total laryngectomy involves permanent loss of natural voice — informed consent must include discussion of TEP prosthesis, electrolarynx, esophageal speech; involve SLP preoperatively; ensure decision-making capacity and consider patient values

Board pearl: A patient with hoarseness, neck bruising, and subconjunctival hemorrhage after a "fall" — suspect strangulation/IPV. Document, image (CT angio neck for vascular injury), screen for safety, offer resources, and follow your state's reporting requirements. This vignette appears on Step 3 with increasing frequency.

High-Yield Associations and Rapid-Fire Facts

Key distinction: Curtain sign (palate deviation away from a vagal lesion) localizes to CN X above the RLN takeoff — i.e., a high vagal lesion (skull base) rather than an isolated RLN lesion. Imaging extends to skull base in this scenario, not just to mediastinum.

Left RLN > right RLN paralysis — longer course around aortic arch; left-sided isolated paralysis = think lung/mediastinum.
Pancoast tumor triad: Shoulder pain + Horner syndrome + hand weakness; add hoarseness if RLN involved.
Ortner syndrome (cardiovocal): Left RLN compression by enlarged left atrium (mitral stenosis), aortic aneurysm, or PA dilation.
Reinke edema: Middle-aged female smoker with deep voice — Marilyn Monroe/Brenda Lee phenotype.
Singers' nodules: Bilateral, junction of anterior 1/3 and posterior 2/3 (point of maximal vibration).
HPV 6 and 11: Recurrent respiratory papillomatosis.
HPV 16: Oropharyngeal SCC (not classically laryngeal).
Saddle nose + subglottic stenosis + hematuria: GPA — get ANCA (c-ANCA/PR3).
Cherry-red epiglottis: H. influenzae epiglottitis (less common post-Hib vaccine).
Thumbprint sign: Lateral neck XR in epiglottitis.
Steeple sign: AP neck XR in croup.
Bovine cough: Vocal cord paralysis (weak glottic closure prevents intrathoracic pressure buildup).
Hot potato voice + drooling + tripoding: Supraglottitis.
Botulinum toxin to thyroarytenoid: Adductor spasmodic dysphonia.
LSVT-LOUD: Voice therapy for Parkinson hypophonia (and presbylarynx).
Curtain sign on palate: CN X (vagal) palsy — uvula deviates AWAY from lesion.
Cricoarytenoid arthritis: RA — morning hoarseness, joint stiffness analog.
Subglottic stenosis trio: Idiopathic (women 30–50), post-intubation, GPA.
Empiric PPI without scope: AAO-HNS recommends AGAINST.
Antibiotics in acute laryngitis: AAO-HNS recommends AGAINST.
Voice rest: True silence — whispering is more traumatic than soft speech.
Hoarseness >2 weeks: Laryngoscopy referral, always.
Smoking cessation + alcohol moderation: Single largest modifiable risk for laryngeal SCC.
Annual scope after laryngeal cancer treatment: Per NCCN, declining frequency over 5 years.

Board Question Stem Patterns

— 56-year-old smoker, hoarseness for 3 weeks, no other symptoms, normal oropharynx. Best next step? → Flexible laryngoscopy referral. Distractors: empiric PPI, amoxicillin, CXR, observation.

— 62-year-old smoker, hoarseness, new ptosis and miosis on the left. Scope shows left vocal cord paralysis. Next step? → CT chest with contrast (and ENT continues care). Look for apical lung mass.

— Patient 2 hours post-thyroidectomy develops stridor and aphonia. Action? → Bedside flexible laryngoscopy, prepare for intubation/tracheostomy. Bilateral RLN injury vs neck hematoma — examine the wound.

— 28-year-old with URI and hoarseness × 4 days. Treatment? → Supportive care, voice rest, hydration. Distractor: azithromycin, prednisone, omeprazole.

— Morning hoarseness, throat clearing, globus, no heartburn. Scope shows posterior laryngeal erythema and arytenoid edema. Management? → PPI BID + lifestyle × 8–12 weeks.

— Unvaccinated 4-year-old, fever 39°C, drooling, tripoding, muffled voice. First step? → Do not agitate, call OR, ENT/anesthesia for airway in controlled setting; ceftriaxone after airway secured.

— 18-month-old, barking cough, hoarseness, mild stridor at rest. Treatment? → Dexamethasone 0.6 mg/kg PO/IM, racemic epinephrine nebulized if moderate-severe.

— Asthmatic on fluticasone develops hoarseness; oropharynx shows white plaques. Cause and management? → Oral candidiasis from ICS; nystatin swish/swallow, spacer, mouth rinsing after dosing.

— Hoarseness, petechiae, neck bruising after "fall." Workup? → CT angio neck, document, screen for IPV, offer resources, mandatory reporting per state law.

— Strained, strangled voice for years; whispering and singing spared. Treatment? → Botulinum toxin to thyroarytenoid.

Step 3 management: When the stem includes smoker + hoarseness + weeks of duration, the highest-yield single answer across question variants is laryngoscopy referral (or CT chest if cord paralysis is already shown). Resist the urge to pick "empiric PPI" or "trial of antibiotics" — both are explicit guideline-against options.

One-Line Recap

Acute hoarseness <2 weeks in a URI context is viral, needs only supportive care and voice rest; any hoarseness ≥2 weeks — and any red flag at any time — mandates flexible laryngoscopy, with the workup branching by what the scope shows.

Board pearl — the single highest-yield Step 3 rule for this topic: Hoarseness ≥2 weeks → flexible laryngoscopy referral. No empiric antibiotics. No empiric PPI in the absence of GERD symptoms or scope findings. No waiting another month. Earlier referral catches early-stage laryngeal SCC when cure rates exceed 90%, and it is the consistently correct ambulatory management answer across question variants.

Acute viral laryngitis: No antibiotics, no empiric PPI, no steroids — supportive care, voice rest (not whispering), hydration, humidification; reassess at 2 weeks.
Chronic/red-flag hoarseness: Flexible laryngoscopy is the entry point. Smokers, hemoptysis, dysphagia, otalgia, neck mass, post-neck/thoracic surgery — refer expeditiously to ENT.
Vocal cord paralysis: Image the recurrent laryngeal nerve from skull base to mediastinum (CT neck + chest with contrast); left-sided isolated paralysis in a smoker = rule out lung cancer.
Laryngopharyngeal reflux: Diagnose by symptoms + laryngoscopy findings, treat with PPI BID + lifestyle × 8–12 weeks; do NOT prescribe empiric PPI before laryngoscopy in isolated dysphonia.
Benign mucosal lesions (nodules, polyps, cysts, Reinke): Speech-language pathology voice therapy first; phonomicrosurgery for non-responders or selected lesions; smoking cessation for Reinke.
Airway red flags (stridor, drooling, tripoding, post-thyroidectomy stridor): Stop the routine workup, escalate to controlled airway management with ENT/anesthesia, avoid agitating the patient.
Special populations: Avoid NSAIDs late in pregnancy and high-dose fluconazole in 1st trimester; consider epiglottitis in unvaccinated children; treat presbylarynx with voice therapy first; screen for IPV/strangulation when neck trauma signs accompany dysphonia.
