Abstract

The purpose of this study was to evaluate the cochlear function in patients with diabetes mellitus by analysis of evoked otoacoustic emissions (EOAE). EOAE were studied in 20 diabetic patients with normal hearing. The parameters used for analysis were the EOAE intensity and amplitude measured per 100 Hz frequency bands between 700 and 4000 Hz These data were compared to the data obtained in a group of non-diabetic control subjects with normal hearing using a Student's t test. The mean EOAE intensity and amplitude by 100 Hz frequency band was significantly lower in diabetic patients than in the control group. This seems to indicate the existence of an alteration in cochlear micromechanics in diabetic patients possibly due to changes in the functioning of the hair cells.

摘要

本研究的目的是通过分析诱发耳声发射（EOAE）来评估糖尿病患者的耳蜗功能。对20名听力正常的糖尿病患者进行了EOAE研究。用于分析的参数是在700至4000Hz之间每100Hz频带测量的EOAE强度和幅度。使用学生t检验将这些数据与一组听力正常的非糖尿病对照受试者获得的数据进行比较。糖尿病患者每100Hz频带的平均EOAE强度和幅度明显低于对照组。这似乎表明糖尿病患者存在耳蜗微机械功能改变，可能是由于毛细胞功能变化所致。
