【摘要】：目的分析90岁以上老年性聋患者听性脑干反应(ABR)的特征。方法对14例90岁以上老年性聋患者(平均年龄91.1.4±1.3岁,26耳)进行交替短声ABR测试。听力正常人9例(平均年龄22.7±1.2岁,18耳)作为对照组。观测Ⅰ、Ⅲ、Ⅴ波的峰潜伏期(PeakLatency,PL)和Ⅰ-Ⅲ、Ⅲ-Ⅴ、Ⅰ-Ⅴ波间期(Inter-PeakLatency,IPL),并分别与对照组总体均数进行比较。结果总体的I波引出率和III波引出率均为76.9%(20/26),V波引出率为84.6%(22/26)。高龄老年性聋组各波PL较对照组延长。Ⅰ-Ⅲ波IPL、Ⅲ-Ⅴ波IPL、Ⅰ-Ⅴ波IPL无组间统计学差异。结论 90岁以上高龄老年性聋患者ABR波形分化较差。
