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.

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
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.
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.
