摘　　要：目的:分析感音性耳聋患者脑干听觉诱发电位检查结果,探讨其对病变部位定位和预后评估的价值。方法:242例感音性耳聋患者,100例年龄和性别相匹配的健康志愿者进行脑干听觉诱发电位检测。结果:周围性耳聋的脑干听觉诱发电位异常表现为Ⅰ波潜伏期延迟或Ⅰ波消失,重者Ⅰ～Ⅴ波消失。中枢性耳聋因病变性质、部位、大小的不同,使脑干听觉诱发电位异常表现形式多样化。药物中毒和老年动脉硬化性耳聋患者预后不良。结论:脑干听觉诱发电位对脑干听觉传导路病变的定位和患者预后的评估有重要价值,但不能对病变定性。AIM: To analyze the checking results of brain stem auditory evoked potential(BAEP) in patients with neurosensory deafness, and study the value to estimate location of lesion and evaluate prognosis.METHODS: The BAEP was detected in 242 neurosensory deafness patients and 100 age and gender matched healthy volunteers.RESULTS: The abnormal appearances of BAEP in peripheral deafness were that absolute latency of Ⅰ wave delayed orⅠ wave disappeared.Ⅰ - Ⅴ wave disappeared in the severe patients. However, abnormal appearances of central deafness were variable due to the different character, location and volume.Unfavorable prognosis existed in the neurosensory deafness patients with drug poisoning and senile arteriosclerosis.CONCLUSION: BAEP has important value to estimate location of lesion and to evaluate prognosis, but it can not estimate quality of disease.
