Table 1. Diagnostic criteria for definite and probable Ménière’s disease (MD) 1.
| Definite MD |
|---|
| A. Two or more spontaneous episodes of vertigo, each lasting 20 minutes to 12 hours |
| B. Audiometrically documented low- to medium-frequency sensorineural hearing loss
in one ear, defining the affected ear on at least one occasion before, during, or after one of the episodes of vertigo |
| C. Fluctuating aural symptoms (hearing, tinnitus, or fullness) in the affected ear |
| D. Not better accounted for by another vestibular diagnosis |
| Probable MD |
| A. Two or more episodes of vertigo or dizziness, each lasting 20 minutes to 24 hours |
| B. Fluctuating aural symptoms (hearing, tinnitus, or fullness) in the affected ear |
| C. Not better accounted for by another vestibular diagnosis |
Clinical research studies should include only patients with definite MD. Probable MD must be considered when no reliable hearing test has confirmed the temporal relationship between the episode of vertigo and the hearing loss.
