Abstract：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.
