综合分析ＢＡＥＰ各项指标，应用ＣＰＡ病变的ＢＡＥＰ４型诊断标准，从６００例可疑听神经瘤患者中，诊断出ＣＰＡ肿瘤５４例，同时发现４例假阳性。本文的假阳性率为７％（４／５８），较多数文献报道为低。在诊断听神经瘤中，ＢＡＥＰ的峰间期比波的绝对潜伏期准确，只有Ⅰ～Ⅲ峰间期增大所导致的Ⅰ～Ⅴ峰间期增大，才有诊断价值，ＢＡＥＰ只有定位作用，无定性价值，故ＢＡＥＰ诊断听神经瘤必须结合临床表现才有意义。在临床上即使已有明确的长束征时，但ＢＡＥＰ无健侧Ⅳ～Ⅴ波的改变，仍可排除肿瘤的诊断。在ＢＡＥＰ的Ⅳ型中，当健侧Ⅳ～Ⅴ波正常时，应参考复合检查，若其阴性则可排除肿瘤的诊断。
Comprehensive analysis of BAEP indicators, the application of CPA disease BAEP4 diagnostic criteria, from 600 patients with suspected acoustic neuroma diagnosed CPA tumor in 54 cases, while 4 cases were found false positive. The false positive rate of this article was 7% (4/58), the majority reported in the literature as low. In the diagnosis of acoustic neuroma, the absolute peak latency of BAEP is higher than that of BAEP. Only the increase of peak Ⅰ ~ Ⅴ caused by the increase of Ⅰ ~ Ⅲ peak interval has the value of diagnosis, and BAEP has only localization effect. Qualitative value, so BAEP diagnosis of acoustic neuroma must be combined with clinical manifestations of significance. In clinical even if there is a clear long beam sign, but BAEP non-contralateral Ⅳ ~ Ⅴ wave changes, can still rule out the diagnosis of cancer. In BAEP type Ⅳ, when the contralateral Ⅳ ~ Ⅴ wave normal, should refer to the composite examination, if negative can rule out the diagnosis of cancer.
