【摘要】 目的探讨脑干听觉诱发电位(BAEP)在检测先天性耳聋儿童听神经通路的病变情况、诊断方面的价值。方法对76例先天性耳聋儿童进行睡眠状态下的BAEP监测。测I～V各波峰潜伏期(PL)和峰间潜伏期 (IPL),对其结果进行分析。结果 76例先天性耳聋儿童脑干诱发电位的异常率为99．1％。其中24例(22．2％) 双侧Ⅰ、Ⅲ、Ⅴ波波形消失;20例(18．5％)一侧波形消失(其中15例为对侧波形消失,5例为对侧Ⅰ、Ⅲ、Ⅴ波潜伏期延长);53例(49．1％)双侧波形缺如;10例(9．3％)Ⅰ、Ⅲ、Ⅴ波潜伏期延长。结论 BAEP对早期诊断儿童先天性耳聋有重要的临床价值。更多还原

【Abstract】 Objective: To study the value of brainstem auditory evoked potential (BAEP) in the observation of the childen who had been deaf before they were born. Methods: 76 patients were assessed by BAEP in the study. The peak latency (PL) and interpeak latency (IPL) of wave I - V were measured. The analysis of data was carried out and the abnormal manifestations of patientswere analysed. Results: The abnormal degree and main manifestations of the shapewere analysed by BAEP in the study. Conclusion: The BAEP is considered to be valuable in the diagnosis of the childen who had been deaf before they were born. The BAEP can assist in the early diagnosis.更多还原
