| 摘 要： | 对40例头部外伤后主诉听力下降者进行听觉用干反应测试并行临床分析,旨在探讨头部外伤后听觉脑干反应与损伤部位及听力损失大型的关系。结果表明,听力损失率为57．5％,听觉用干反应异常率为33．75％,外伤检查时发现中耳及内耳先天性畸形5％。头部外伤后听觉用干反应的异常类型无固定模式,而与损伤部位及程度有关。听觉脑干反应异常类型表现为有各波潜伏期延长,但中枢传导时间正常;Ⅰ波消失,Ⅲ～Ⅴ波间期正常;Ⅰ～Ⅲ波消失,Ⅴ波绝对潜伏期延长;单耳Ⅰ～Ⅴ波间期延长等。头部外伤后进行听觉脑干反应检测有助于确定听通路损伤的部位及听力损失类型。

| Abstract: | The study investigated brain auditory evoked potentials (BAEP) in patients complaining auditory disturbances after head trauma. The results showed that the incidence of hearing loses was 57.5% and the rate of abnormality of BAEP is 33.75%. The types of the abnormalities of BAEP varied and were related with the position and severity of the head trauma. The types of the abnormalities manifested as loses of I-II waves, prolongation of V latency and I-V interlatency. |
