Auditory brain-stem response (ABR) results are reported on three cases of acoustic tumors and two cases with brain-stem lesions. These cases highlight several considerations in the clinical use of ABR. The sensitivity of ABR to retrocochlear involvement in light of normal pure-tone hearing and cochlear hearing loss is shown in the first two cases. The third case shows the advantage of "contralateral" ABR testing and a unique effect of stimulus polarity. The use of an intensity function and high presentation rate procedures are shown to be helpful diagnostic procedures in case four. Case five shows bilateral ABR effects which correlate well with the degree of brain-stem involvement. In addition to the ABR data, audiologic, radiologic, and medical findings on these patients are also discussed.
报告了3例听神经瘤和2例脑干病变患者的听觉脑干反应（ABR）结果。这些病例突出了ABR临床应用中的几个注意事项。前两个病例显示了在纯音听力正常和耳蜗性听力损失情况下，ABR对蜗后病变的敏感性。第三个病例显示了“对侧”ABR测试的优势以及刺激极性的独特作用。在第四个病例中，强度函数和高刺激率程序的应用被证明是有用的诊断方法。第五个病例显示了双侧ABR效应，与脑干受累程度密切相关。除了ABR数据外，还讨论了这些患者的听力学、放射学和医学检查结果。
