Thirty patients with cerebello-pontine angle tumours were studied with brain-stem electrical responses (BSER). Twenty-one of the patients had acoustic neuromas. Two other patients had meningiomas, one a lymphoma, one a chordoma, two patients arterio- venous malformations, and two aneurysms in the cerebello-pontine angle. In eight cases no BSER-waves could be evoked. In 13 cases with a Wave V present this wave was significantly delayed in all cases. The inter-aural time difference (IT5) and the I-V interval was prolonged in all those cases in which these parameters could be estimated, In nine cases, only the earlier components of the BSER (I and III) could be distinguished although Wave II was often missing. In all 30 cases studied the BSER was pathological, indicating a cerebello-pontine angle lesion.
对30例桥小脑角肿瘤患者进行了脑干电反应（BSER）研究。其中21例患者患有听神经瘤。另外2例患者患有脑膜瘤，1例患有淋巴瘤，1例患有脊索瘤，2例患有桥小脑角动静脉畸形，2例患有桥小脑角动脉瘤。8例患者无法引出BSER波。在13例出现V波的病例中，该波在所有病例中均明显延迟。在所有能够评估这些参数的病例中，双耳时间差（IT5）和I-V间期均延长。9例患者中，尽管II波常常缺失，但仅能分辨出BSER的早期成分（I波和III波）。在所有研究的30例病例中，BSER均为病理性，提示存在桥小脑角病变。
