The authors examined brain stem acoustic evoked potentials (BAEP) in 10 children aged 2-14 years with tumours in the posterior cranial fossa infiltrating the cerebellum and brain stem. The tumours were diagnosed by computed tomography and in eight patients confirmed on operation. For stimulation a monaural click was used. The authors assessed the latency of waves, intervals between and investigated the presence of waves and evaluated their amplitudes. They compared the results with normal values. In abnormal findings the latency of components was delayed, the components were generated in a rostral manner from the site of the lesion in all children. In four patients with severe affections of the brain stem the investigated components were lacking. In nine patients the BAEP evoked by monaural stimulation helped to asses the lateralization of the lesion. In eight patients a bilateral abnormality of the V wave was recorded. The most sensitive indicator for assessment of the site of the lesion was assessment of the interval between two consecutive waves.
作者对10名年龄在2至14岁、患有后颅窝肿瘤并浸润小脑和脑干的儿童进行了脑干听觉诱发电位（BAEP）检查。这些肿瘤通过计算机断层扫描诊断，8例患者经手术证实。刺激采用单耳短声。作者评估了波的潜伏期、波之间的间隔，研究了波的存在情况并评估了其振幅。他们将结果与正常值进行了比较。在异常结果中，各波成分的潜伏期延迟，在所有儿童中，成分均从病变部位以头端方向产生。在4例脑干严重受累的患者中，所研究的成分缺失。在9例患者中，单耳刺激诱发的BAEP有助于评估病变的侧别。在8例患者中记录到V波双侧异常。评估病变部位最敏感的指标是评估两个连续波之间的间隔。
