Auditory Brainstem Responses in Senile Presbycusis Patients over 90 years

AbstractObjectiveTo analyze the characteristics of auditory brainstem response (ABR) in presbycusis patients elder than 90 years.MethodsFourteen presbycusis patients elder than 90 years (presbycusis group, 91.1.4± 1.3 years, 26 ears) and 9 normal-hearing young adults (control group, 22.7±1.2 years, 18 ears) participated in the study. Alternative click-evoked ABRs were recorded in both groups. The peak latency (PL) of peak I, III, and V, and the inter-peak latency (IPI) of I-III, III-V, and I-V were compared between groups.ResultsIn elder presbycusis patients, the occurrence rate of peak I and III were both 76.9%, and that of peak V was 84.6%. In presbycusis group, the peak latencies of I, III, V were significantly longer than that of control group (P
