摘　　要：目的 :探讨脑干听觉诱发电位 (BAEP)在小脑桥脑角 (CPA)肿瘤诊断中的意义。方法 :对已确诊的 17例CPA肿瘤患者进行BAEP检测 ,并与 5 3例 (10 6耳 )正常对照组进行比较分析。结果 :17例CPA肿瘤患侧BAEP均异常 ,其中Ⅰ～Ⅲ或Ⅰ～Ⅴ峰间期延长是CPA肿瘤患者较特异和敏感的指标 ;16例CPA肿瘤对侧BAEP异常 ,多提示对侧脑干受压移位。结论 :BAEP是早期诊断CPA肿瘤的一种经济、有效和无创性的检测方法。Objective:To investigate the diagnostic singnificance of brainstem auditory evoked potentials (BAEP) in patients with cerebellopontine angle tumours (CPAT).Methods:BAEP were studied in 17 patients with CPAT verified by the clinic and compared with 53 cases (106 ears) normal persons.Results:All CPAT had abnormal BAEP on the tumour side, among them prolonged Ⅰ～Ⅲ or Ⅰ～Ⅴ interpeaklatency was special and sensitive. 16 CPAT had abnormal BAEP on the contralateral side, probably due to distortion and compression of the brainstem. Conclusions: BAEP is an economical,effective and harmless test in early diagnosis to CPAT.
