本文对65例（130耳）弱智儿童进行听觉脑干反应（ABR）检测，发现其中57例（101耳）出现异常波形。表现为听阈升高（77．69％），波潜伏期延长（56．92％），波幅明显降低（59．23％），波间潜伏期延长（25．39％）及波缺失等。显示听路损害发生在耳蜗和听神经远端；少数可损及中枢听觉通路。我们认为，对弱智儿童作ABR可早期发现其听觉功能的潜在性损害。
In this study, auditory brainstem response (ABR) was detected in 65 cases (130 ears) of mentally retarded children and 57 cases (101 ears) were found to have abnormal waveform. (77.69%), prolongation of wave latency (56.92%), decrease of wave amplitude (59.23%), prolongation of wave latency (25.39%) and wave loss. Disturbance of hearing ailments occurred distal to the cochlea and auditory nerve; few could impair the central auditory pathway. We believe that the potential damage to ABR early detection of auditory function in mentally retarded children.
