Vector analysis of BAEPs was done in 10 patients with posterior fossa tumors and 14 patients with MS. Latency abnormalities were found in both groups without significant differences. However, deviations of wave V vectors from its normal orientation were observed in tumor cases, correlated with tumor size and latency increase. It is concluded that vector deviations may indicate distortion of auditory pathways in the brain-stem.
对10例后颅窝肿瘤患者和14例多发性硬化症患者进行了脑干听觉诱发电位（BAEP）的矢量分析。两组均发现潜伏期异常，但无显著差异。然而，在肿瘤病例中观察到V波矢量偏离其正常方向，这与肿瘤大小和潜伏期延长相关。结论是，矢量偏差可能表明脑干听觉通路存在扭曲。
