目的 探讨脑干听觉诱发电位 (BAEP)在诊断突发性耳聋 (突聋 )和判断预后中的价值。方法 选取 5 8例突聋病例 ,共 75例患耳 ,分别在治疗前、后及其后的 5～ 6个月行BAEP检查。结果 客观听力不同程度损失 ,主波分化有 4种情况 :①Ⅰ、Ⅲ、Ⅴ波都能引出 ,各主波峰潜伏期 (PL)、峰间潜伏期 (IPL)在正常范围 ;②Ⅰ、Ⅲ、Ⅴ波都能引出 ,各PL均延长 ,IPL正常 ;③Ⅰ、Ⅲ、Ⅴ波都能引出 ,IPL延长 ;④各主波有不等缺失。并且主波缺失越多 ,客观听力损失数越大。突聋组与正常组对照及治疗后与治疗前对照PL、客观听力损失值有显著性差异 (P <0 0 1) ;治疗后与其后 5～ 6个月对照均无显著性差异 (P >0 0 5 )。中青年组与老年组对比 ,在PL和客观听力损失数治疗前后差值方面有显著性差异 (P <0 0 5或P <0 0 1)。结论 对于突聋的诊断和预后判断具有重要价值
Objective To investigate the value of brainstem auditory evoked potential (BAEP) in diagnosing sudden deafness (sudden deafness) and prognosis. Methods Fifty-eight cases of sudden deafness were selected and 75 cases were affected. BAEP was performed 5 to 6 months before and after treatment. The results of objective hearing loss to varying degrees, the main wave of four cases: ① Ⅰ, Ⅲ, Ⅴ waves can lead to the main peak latency (PL), peak latency (IPL) in the normal range; ② Ⅰ, Ⅲ, Ⅴ wave are Can lead to the extension of all PL, IPL normal; ③ Ⅰ, Ⅲ, Ⅴ wave can lead, IPL prolongation; And the more the main wave is missing, the greater the objective hearing loss. There was significant difference between the control group and the control group (P <0.01) and the objective hearing loss (P <0.01) between the control group and the normal group after treatment, and no significant difference between 5 and 6 months after treatment 0 0 5). Compared with the elderly group, there was a significant difference (P <0.05 or P <0.01) between the PL and the objective hearing loss before and after treatment. Conclusions for sudden deaf diagnosis and prognosis of great value
