83例聋(哑)病人ABR检查报告分析

The ABR Examination of 83 Cases with Deaf-mutism

为了解聋哑病人的残余听力情况，对83例（166耳）进行了ABR检查，结果发现20例（39耳）各波形分化良好：19耳反应阈值20dB，提示了听力属正常范围，估计应为智力发育迟缓或语言发言障碍：3例（3耳）畸形者，健耳正常范围，患耳反应阈值80dB，提示仍有残余听力存在。80耳各波未引出。至于后天性的聋哑儿童，多有氨基糖甙类药物中毒史，应高度引起重视。对婴幼儿应早期发现和确定有无听力损失．以最大限度地减少因听觉障碍造成的智力发育障碍和残疾。

The ABR examination of 83 cases (166 ears ) was done to study residual hearlng of deafmutism. The results showed that every wave of 20 cases (39 ears) was split well. The reactive threshold was 20dB in 19 ears, because of intelligence hypoplasia or speech dysplasia in 3 cases (3 ears) with malformation,the reactive threshold was normal on healthy ear and 80dB on sick ear. It shows residual hearing exists.Thcre was no wave to be recorded in 80 ears. About children of acquired deaf-mutism, the most of them had aminoglucosides poisoning history. We must pay attention to it. The hearing level in babies and infants should be determined early in order to reduce intelligence hypoplasia and deformity beause of hearing loss.
