Abstract：Objective To report the response rate and characteristics of various parameters of ocular ves-tibular evoked myogenic potentials in patients with sudden sensorineural hearing loss (SSHL). Methods Thir-ty six cases of unilateral SSHL examined between October 2014 and March 2015 were included as the study group. Twenty five age-and gender-matched normal subjects were recruited as the control group. Both pa-tients and normal subjects underwent conventional air conduction ocular vestibular evoked myogenic poten-tial (oVEMP) tests in bilateral ears. The results were compared between the affected and contralateral ears and with the normal controls. Results oVEMPs were elicited in 16 affected ears (44.4%), 19 contralateral ears (52.7%) and 50 normal ears (100%) (P<0.05).oVEMP parameters (N1 latency, P1 latcncy, latency in-tervals and amplitudes) were not significantly different among the groups (P>0.05). Conclusions The utricle and superior vestibular nerves may be damaged in SSHL patients. Such damages may be monitored objec-tively by oVEMP examinations.
