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（Peak Latency，PL）和Ⅰ-Ⅲ、Ⅲ-Ⅴ、Ⅰ-Ⅴ波间期（Inter-Peak Latency，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。

Objective To obtain the characteristics of auditory brainstem response (ABR) in senile patietns elder than 90 years. Methods Fourteen presbycusis patietns elder than 90 years (91.1±1.3 years, 26 ears) and 9 normal-hearing adults ( 22.7±1.2 years, 18 ears) were included in the study. ABRs were recorded in both groups by alternative clicks. The peak laten-cy (PL) of wave Ⅰ, Ⅲ, and Ⅴ, and the inter-peak latency (IPL) of Ⅰ-Ⅲ, Ⅲ-Ⅴ, and Ⅰ-Ⅴ were compared between groups. Results In 76.9%(20/26) of senile ears, wave I of ABRs were present, in 76.9%(20/26) of them, wave I of ABRs were present, and in 84.6%(22/26) of them, waveⅤwere present. For the senile group, the peak latencies ofⅠ,Ⅲ,Ⅴwere statistically longer than those of control group. There was no statistical difference between groups in the IPL of waveⅠ-Ⅲ, waveⅢ-Ⅴand waveⅠ-Ⅴ. Conclusion Worse ABR wave differentiation were found in senile patients over 90 years.
