Ménière’s disease is an inner-ear disorder caused by endolymphatic hydrops, characterised by recurrent episodes of vertigo, fluctuating hearing loss, and tinnitus. Ménière’s disease can be classified as ‘probable’ and ‘definite’ according to the criteria determined by the Bárány Society.

This analytical cross-sectional retrospective study included 28 Ménière’s disease patients (15 with definite Ménière’s disease and 13 with probable Ménière’s disease). Vestibular function was assessed using ocular-vestibular evoked myogenic potentials, cervical-vestibular evoked myogenic potentials and caloric test.

The results of these tests were evaluated separately for probable Ménière’s disease and definite Ménière’s disease groups and comparisons were made. Significant differences in vestibular evoked myogenic potential asymmetry rates were observed between the probable Ménière’s disease and definite Ménière’s disease groups, with the definite Ménière’s disease group exhibiting a higher rate of abnormal responses.

This suggests that vestibular evoked myogenic potentials testing may be a valuable tool in distinguishing between these two subtypes of Ménière’s disease. Further research is necessary to validate these findings and explore their implications for clinical practice.
