Diagnostic Criteria for Ménière's Disease
Ménière's disease is diagnosed as "definite" when a patient has ≥2 spontaneous vertigo attacks lasting 20 minutes to 12 hours, audiometrically documented low- to mid-frequency sensorineural hearing loss, and fluctuating aural symptoms (hearing loss, tinnitus, or ear fullness) in the affected ear, with other causes excluded 1.
Definite Ménière's Disease Criteria
All four of the following must be present 1:
≥2 spontaneous vertigo attacks, each lasting 20 minutes to 12 hours
- Vertigo must be true rotational spinning sensation, not just imbalance or lightheadedness
Audiometrically documented low- to mid-frequency sensorineural hearing loss in the affected ear
- Must be documented on at least 1 occasion before, during, or after one of the vertigo episodes
- Audiometry is mandatory—clinical suspicion alone is insufficient
Fluctuating aural symptoms in the affected ear
- Hearing loss, tinnitus, OR ear fullness
- Note: Fluctuation is required for aural symptoms but hearing loss documented on audiometry may be fluctuating OR non-fluctuating
Other causes excluded by appropriate testing
Probable Ménière's Disease Criteria
All three of the following must be present 1:
≥2 episodes of vertigo or dizziness lasting 20 minutes to 24 hours
- Note the broader time window (up to 24 hours vs. 12 hours for definite)
- Allows for "dizziness" not just true vertigo
Fluctuating aural symptoms (hearing loss, tinnitus, or fullness) in the affected ear
- Can be fluctuating OR non-fluctuating
Other causes excluded by other tests
Critical Diagnostic Distinctions
The key difference between definite and probable Ménière's disease is the requirement for audiometrically documented hearing loss in definite disease 1. Probable disease allows for a broader clinical presentation without mandatory audiometric confirmation, extending the vertigo duration window to 24 hours and accepting "dizziness" rather than requiring true vertigo.
Important Caveats
Audiometry is non-negotiable for definite diagnosis—you must obtain formal audiometric testing showing low- to mid-frequency sensorineural hearing loss 1
Serial audiometry may be necessary: In one study, only 28.6% of patients showed fluctuating hearing when multiple audiograms were available, highlighting that a single audiogram may miss the fluctuating pattern 2
Early-stage disease is challenging: Patients with monosymptomatic presentations or early disease may not meet full criteria initially and require longitudinal follow-up 2
Exclude mimics systematically: Vestibular migraine is the most common diagnostic challenge—it can present with similar duration attacks but typically lacks the documented low-to-mid frequency hearing loss pattern 3. Other critical exclusions include BPPV (seconds-long positional vertigo), stroke/TIA (neurologic signs, no hearing loss), and autoimmune inner ear disease (often bilateral, steroid-responsive) 1
