Ménière Disease

Inner-ear disorder of recurrent vertigo episodes, fluctuating low-frequency sensorineural hearing loss, tinnitus, and aural fullness.

Also known as: Meniere disease, endolymphatic hydrops, Ménière's disease

Overview

An idiopathic inner-ear disorder characterized by recurrent spontaneous episodes of vertigo lasting 20 minutes to 12 hours, accompanied by fluctuating low- to mid-frequency sensorineural hearing loss, tinnitus, and aural fullness in the affected ear (per Bárány Society / AAO-HNS criteria).

Epidemiology

Prevalence ~200 per 100,000. Onset typically between ages 40 and 60. Female predominance ~1.3:1. Bilateral involvement develops in 25-50% over years. Genetic predisposition (HLA associations, familial clusters).

Question 1NeurologyMedium
A 49-year-old woman has episodic vertigo lasting hours, fluctuating hearing loss, tinnitus, and aural fullness. Which of the following best explains this disorder?
  • ACerebellar infarction from an embolus
  • BOtoliths displaced into the posterior canal
  • CExcess endolymphatic fluid pressure
  • DReactivation of vestibular nerve herpesvirus
Reveal answer & full explanation
Correct answer: C — Excess endolymphatic fluid pressure
  • ACerebellar infarction from an embolus
  • BOtoliths displaced into the posterior canal
  • CExcess endolymphatic fluid pressure
  • DReactivation of vestibular nerve herpesvirus

Why Excess endolymphatic fluid pressure is correct

  • Ménière disease reflects endolymphatic hydrops, an overaccumulation of endolymph that distends the membranous labyrinth.
  • This produces the classic tetrad of episodic vertigo lasting 20 minutes to hours, fluctuating sensorineural hearing loss, tinnitus, and aural fullness.
  • The cochlear plus vestibular involvement together distinguish it from purely positional or purely vestibular causes.

Why the others are wrong

  • Otoliths displaced into the posterior canal — Canalithiasis causes BPPV, which is brief seconds-long positional vertigo WITHOUT hearing loss or tinnitus (vertigo-subtype trap).
  • Reactivation of vestibular nerve herpesvirus — Vestibular neuritis causes a single days-long vertiginous spell after a viral illness and spares hearing, unlike this fluctuating cochlear picture (right-organ-wrong-pattern).
  • Cerebellar infarction from an embolus — A cerebellar stroke gives continuous vertigo with ataxia and other neurologic deficits, not recurrent attacks with aural fullness (dangerous-mimic trap).
Question 2NeurologyMedium
A 48-year-old woman presents with a 6-month history of recurrent spontaneous episodes of spinning vertigo, each lasting 2 to 3 hours and accompanied by nausea and vomiting. During the episodes she notices a roaring, low-pitched ringing and a sense of pressure in her right ear, along with muffled hearing on that side that improves between attacks. She denies headache, photophobia, and positional triggers. An audiogram performed after a recent attack shows fluctuating low-frequency sensorineural hearing loss in the right ear, and MRI of the internal auditory canals is normal. Which of the following is the most likely diagnosis?
  • ABenign paroxysmal positional vertigo
  • BVestibular migraine
  • CMénière disease
  • DVestibular neuritis
Reveal answer & full explanation
Correct answer: C — Ménière disease
  • ABenign paroxysmal positional vertigo
  • BVestibular migraine
  • CMénière disease
  • DVestibular neuritis

Why Ménière disease is correct

  • The Bárány Society / AAO-HNS 2015 criteria define definite Ménière disease as ≥2 episodes of spontaneous vertigo lasting 20 minutes to 12 hours, plus audiometrically documented low- to mid-frequency sensorineural hearing loss in the affected ear, plus fluctuating aural symptoms (hearing loss, tinnitus, fullness) in that ear, with no better explanation.
  • This patient hits every element: recurrent 2-3 hour spontaneous vertigo, unilateral fluctuating low-frequency SNHL on audiogram, roaring low-pitched tinnitus, and aural fullness on the right.
  • A normal MRI of the internal auditory canals appropriately excludes vestibular schwannoma, supporting the clinical diagnosis.

Why the others are wrong

  • Vestibular migraine is the most common Ménière mimic, but it features headache, photophobia, or phonophobia with usually normal hearing; this patient has no migraine features and has documented unilateral SNHL.
  • Benign paroxysmal positional vertigo causes brief, seconds-long, positionally triggered vertigo reproduced by Dix-Hallpike, with no hearing loss or tinnitus; her episodes are spontaneous, prolonged, and include cochlear symptoms.
  • Vestibular neuritis is a single prolonged attack of vertigo lasting days after a viral illness, without hearing loss; it does not recur episodically and spares cochlear function.

Risk factors

  • Family history of Ménière disease
  • Autoimmune inner ear disease
  • Migraine (overlap with vestibular migraine)
  • Allergic disorders
  • Possible viral or immune triggers

Pathophysiology

Endolymphatic hydrops — overaccumulation of endolymph distends the scala media and may rupture Reissner's membrane, producing acute potassium-induced injury to vestibular and cochlear hair cells. Etiology of hydrops is multifactorial: impaired endolymph absorption at the endolymphatic sac, autoimmune injury, ionic dysregulation, viral.

Clinical presentation

Symptoms

  • Episodic spontaneous vertigo lasting 20 min to 12 h (rarely up to 24 h)
  • Fluctuating low- to mid-frequency sensorineural hearing loss, typically unilateral
  • Roaring or low-pitched tinnitus that may worsen during episodes
  • Aural fullness or pressure in the affected ear
  • Nausea, vomiting, diaphoresis during episodes
  • Tumarkin 'otolithic crisis' drop attacks (sudden falls without warning, no LOC) in advanced disease

Signs / physical exam

  • Between attacks: exam often normal; later, persistent unilateral sensorineural hearing loss on audiogram
  • Spontaneous horizontal-torsional nystagmus during attacks (initially toward the affected ear in irritative phase, then away as the labyrinth fatigues)
  • Positive head-impulse test toward the affected side once vestibular function is reduced
  • Tuning fork tests (Weber, Rinne) consistent with unilateral SNHL

Classic findings

Recurrent spontaneous vertigo + unilateral low-frequency hearing loss + tinnitus + aural fullness.

Differential diagnosis

  • Vestibular migraine — Recurrent vertigo + migraine features (headache, photophobia, phonophobia, aura); hearing usually normal; responds to migraine prophylaxis
  • BPPV — Brief (seconds), positional vertigo with Dix-Hallpike; no hearing loss; treated with Epley maneuver
  • Vestibular neuritis — Single prolonged episode (days), no hearing loss, follows viral illness; unilateral caloric weakness
  • Labyrinthitis — Single episode with hearing loss; viral or bacterial; does not recur in classic form
  • Acoustic neuroma (vestibular schwannoma) — Progressive unilateral hearing loss + tinnitus; vertigo less prominent; MRI internal auditory canal diagnostic
  • Autoimmune inner ear disease — Bilateral, rapidly progressive sensorineural hearing loss; steroid-responsive
  • Perilymph fistula — Vertigo triggered by Valsalva, sneezing, or pressure changes; recent barotrauma or head injury

Diagnostic workup

Diagnostic criteria

Definite Ménière (Bárány/AAO-HNS 2015): ≥2 episodes of spontaneous vertigo lasting 20 min to 12 h + audiometrically documented low- to mid-frequency SNHL in the affected ear before, during, or after an episode + fluctuating aural symptoms (hearing loss, tinnitus, fullness) in the affected ear + no better explanation.

Labs

  • TSH, CBC, comprehensive metabolic panel, ANA, RPR, B12 (exclude metabolic/autoimmune mimics)
  • Lyme serology in endemic areas

Imaging

  • Pure-tone and speech audiometry — low/mid-frequency SNHL, often fluctuating; word recognition typically preserved early
  • MRI with gadolinium of internal auditory canals — exclude vestibular schwannoma and central pathology
  • Vestibular testing (videonystagmography, caloric, VEMPs) as indicated
  • Electrocochleography — elevated SP/AP ratio supports hydrops (not diagnostic alone)
  • Delayed gadolinium-enhanced MRI inner ear (specialized centers) can visualize hydrops

Treatment

First-line

  • Low-sodium diet (<2 g/day), caffeine and alcohol reduction, smoking cessation
  • Thiazide diuretic (hydrochlorothiazide, often combined with triamterene) or acetazolamide — to reduce endolymph volume
  • Vestibular suppressants for acute attacks: meclizine, dimenhydrinate, promethazine, lorazepam, prochlorperazine — limit to acute use; chronic use impairs vestibular compensation
  • Antiemetics (ondansetron, prochlorperazine) for nausea
  • Patient education and reassurance about benign nature of attacks
  • Vestibular rehabilitation for interictal imbalance

Persistent or refractory disease

  • Intratympanic corticosteroid (dexamethasone) injections — vestibular-sparing, may help hearing and vertigo
  • Intratympanic gentamicin — selectively ablates vestibular hair cells; controls vertigo at the cost of vestibular function (and some hearing risk)
  • Endolymphatic sac decompression — controversial benefit
  • Selective vestibular nerve section — preserves hearing; effective for vertigo control in serviceable-hearing patients
  • Labyrinthectomy — definitive vertigo control but destroys hearing; reserved for non-serviceable hearing

Migraine overlap

  • Trial migraine prophylaxis (propranolol, topiramate, amitriptyline, venlafaxine, magnesium) if vestibular migraine features present
  • Lifestyle measures: sleep, hydration, trigger avoidance

Second-line / adjunct

  • Betahistine — used widely outside the US; evidence mixed; not FDA-approved
  • Hearing aids for permanent SNHL; cochlear implant for severe bilateral hearing loss
  • Counseling and support groups for chronic disease impact

Complications

  • Progressive permanent sensorineural hearing loss
  • Bilateral involvement with cumulative hearing and balance disability
  • Drop attacks (Tumarkin crises) with fall-related injury
  • Chronic anxiety and depression
  • Loss of driving privileges and employment impact
  • Persistent disequilibrium between episodes

PANCE pearls

  • The combination of low-frequency SNHL with fluctuation is highly specific for Ménière — pure high-frequency loss argues for presbycusis or noise exposure.
  • Always image with MRI to exclude vestibular schwannoma before settling on Ménière, especially with unilateral hearing loss.
  • Vestibular migraine is the most common Ménière mimic — overlapping features include episodic vertigo, photophobia, and family history of migraine.
  • Intratympanic gentamicin trades vestibular function for vertigo control; counsel about persistent imbalance.
  • Avoid chronic vestibular suppressants — they prevent central compensation.
