Abstract

Introduction:

Vestibulo-masseteric reflex pathway was assessed in individuals with definite Meniere’s disease using masseter vestibular-evoked myogenic potential (mVEMP). mVEMP’s latency and amplitude parameters were explored and also studied the correlation between mVEMP results of Meniere’s affected ears and duration of the disease.

Methods:

Group I with unilateral definite Meniere’s disease individuals (n = 25; 15 males, 10 females) and Group II with healthy individuals (n = 25; 13 males, 12 females). 500 Hz tone-burst mVEMP was done for Meniere’s affected ears (n = 25), Meniere’s unaffected ears (n = 25), and healthy ears (n = 50) in the ipsilateral mode of stimulation.

Results:

mVEMP responses were present for 22/25 (88%) of Meniere’s affected ears; 25/25 (100%) of Meniere’s unaffected ears, and 25/25 (100%) of healthy individuals. This study found a significant (P < 0.05) p11, n21 peak latency prolongation; reduced EMG unrectified and rectified p11-n21 peak-to-peak amplitude in Meniere’s affected ears than healthy individuals’ ears. Furthermore, found no significant (P > 0.05) differences between Meniere’s affected and unaffected ears for mVEMP response parameters.

Conclusion:

The present study findings suggested the impaired vestibulo-masseteric reflex pathway in individuals with definite Meniere’s disease. In future, mVEMP studies can be steered to understand the various aspects of pathophysiology mechanism of peripheral vestibular disorders.
