Abstract：Objective To report otolith damage in patients with sudden deafness and its influence on prognosis,as well as the correlation between ocular vestibular evoked myogenic potentials(oVEMPs)and subjective visual vertical(SVV).Methods Sixty-six patients with unilateral sudden deafness were selected as the study objects.Based on pres-ence of vertigo,they were divided into a non-vertigo group(n=38)and a vertigo group(n=28).Based on otolith func-tion,they were divided into a normal function group(n=37)and an abnormal function group(n=29).Thirty healthy vol-unteers served as the control group.Pure tone thresholds,oVEMPs,cervical vestibular evoked myogenic potentials(cVEMP)and SVV were obtained before and 2 weeks after treatment,and results and correlation between oVEMP and SVV were analyzed.Results The rates of abnormal oVEMPs,cVEMPs and SVV were higher than in the vertigo group than in the non-vertigo group and the control group(P＜0.05),with no significant correlation between oVEMP and SVV(r=0.138,P＞0.05).The rate of effective treatment for the non-vertigo group was 71.1％,compared to 46.4％for the verti-go group(c2=4.094,P＜0.05);and 73.0％in the normal otolith function group,compared to 44.8％in the abnormal oto-lith function group(c2=5.394,P＜0.05).Conclusion Some patients with sudden deafness can suffer from otolithogenic impairment,with worse prognosis in patients showing vertigo than those without.Otolith function tests have certain val-ue in assessing prognosis in sudden deafness.oVEMP and SVV,as two relatively independent otolith function tests,can complement each other rather than replacing each other.
