本文分析了经CT、手术和病理检查证实的25例桥脑小脑角肿瘤患者的BAEP,发现其主要特征性改变为:两侧BAEP不对称;其异常程度与患者听力损失程度相平行;患侧主波出现不全、V波潜伏期延迟;肿瘤较大者健侧可见V波潜伏期延迟,Ⅲ-Ⅴ波间时程延长,甚至V波消失。由于手术对脑干的影响,术后1～3天内BAEP不宜作为病情监测指标,而手术6天后健侧BAEP可较好的反映手术的效果和术后病人的恢复情况。
In this paper, we analyzed the BAEP of 25 patients with cerebellopontine angle tumor confirmed by CT, surgery and pathological examination and found that the main characteristic changes were: bilateral BAEP asymmetry; the degree of abnormality was parallel to the degree of hearing loss; The main wave appears incomplete, V wave latency is delayed; larger tumor on the right side visible delayed V-wave latency, Ⅲ-Ⅴ wave duration extended, and even V wave disappeared. Due to the impact of surgery on the brain stem, BAEP should not be used as a disease monitoring indicator within 1 ~ 3 days after operation, but BAEP after 6 days of surgery can better reflect the effect of surgery and postoperative patient recovery.
