CVEMP, oVEMP and Caloric Test Results in Individuals with Meniere’s Disease

Abstract

Objective : The present study aimed to characterize cVEMP, oVEMP and caloric test findings in individuals with Meniere’s disease. Methods : 29 participants with Meniere’s disease and 29 participants with normal hearing were enrolled for the study. Out of 29 participants in the experimental group, 25 of them had unilateral Meniere’s disease and 4 of them had bilateral Meniere’s disease (Total 33 ears diagnosed with Meniere’s and 25 ears with non-Meniere’s disease). All the participants underwent routine audiological, cVEMP, oVEMP and Caloric testing. Results : Out of 33 ears with Meniere’s disease, 29 ears had absent responses on cVEMP, 23 ears showed absent oVEMP responses, 27 ears had hypo-activity, five ears showed hyper activity and one ear showed normal response to caloric stimulation. In the contralateral ear (25 ears with non-Meniere’s disease) both cVEMP and oVEMP were absent in 5 of the ears, cVEMP was absent and oVEMP was present in 13 ears, cVEMP was present and oVEMP was absent in 1 ear, whereas both cVEMP and oVEMP were present in 6 ears in individuals with Meniere’s disease. However, the caloric responses were present normally in the contralateral ear in individuals with Meniere’s disease. Conclusions : The combination of cVEMP, oVEMP and caloric test provides valuable information regarding localization of hydrops in individuals with Meniere’s disease.
