Abstract: Objective To establish the normal values of vestibular evoked myogenic potentials (VEMPs) in the patients at early stage of Meniere's Disease(MD), including the latency, interaural latency, rate of amplitude and interaural amplitude difference (IAD) ratio. Methods 39 cases of healthy adults with normal hearing were chosen as the controls, while 37 patients with unilateral Ménière's disease at early stage were enrolled into the MD group. The characteristics of VEMPs in MD group were analyzed. Results In MD group, the rate of abnormal VEMPs was 81.08%, in which VEMPs was not present on affected side in 11 cases and on both sides in 4 cases. The characteristics of the VEMPs consisted of prolonged latency of p13 or n23, prolonged IAL difference, and augmented or depressed amplitude. Conclusion The prolonged IAL difference and altered amplitudes of VEMPs are prominent in the early stage of Meniere's Disease.
