1、听性脑干检测在突发性耳聋中临床应用价值［摘要］目的探❷听性脑干检测在突发性耳聋中的临床应用价值。方法选取2015年1〜12月我院收治的50例突发性耳聋患者作为研究对象，按照发病时间分为两组，观察组1组发病时间W3个月，观察2组发病时间>3个月，与此同时，选择耳科常规检查正常、无既往耳疾病史、纯音听阈25dn内的20耳作为对照组，上述人员均接受听性脑干检测，比较三组各主波的引出率、峰间潜伏期以及潜伏期。结果观察1组、观察2组的I波、III波、V波引出率均显著低于对照组，差异有统计学意义(P0.05)o观察1组、观察2组各波的引出率、潜伏

2、期、峰间潜伏期比较，差异无统计学意义(P>0.05)。结论听性脑干检测在突发性耳聋中的特异性显著，值得临床推广［关键词］听性脑干检测；突发性耳聋；应用价值；引出率；峰间潜伏期［中图分类号］R764.43+7［文献标识码］A［文章编号］1674-4721(2017)04(b)-0119-03ClinicalapplicationvalueofauditorybrainstemdetectioninsuddendeafnessMALiYINXiao-huiDepartmentofEar-Nose-Throat,People7sHospit
