Auditory brain-stem response (ABR) and acoustic reflex test (ART) results were reviewed for 30 patients with cerebellopontile angle tumors and for 30 patients without tumor. Patients included in the nontumor group were selected to match the audiometric configurations for individual patients in the tumor group. The ABR waveforms were abnormal for all but one of the patients with tumor and for seven of the patients without tumor. The ART results were abnormal for 25 of the patients with tumor and two of the patients without tumor. Patients without tumor yielding abnormal ABR results usually had more severe hearing losses than the patients without tumor who demonstrated normal ABR waveforms. The ABR and ART merit continued use in the audiologic examination of patients suspected of having retrocochlear lesions, but obviously, degree of hearing loss and other medical information must be considered also when retrocochlear lesions are suspected.
回顾了30例桥小脑角肿瘤患者和30例无肿瘤患者的听觉脑干反应（ABR）和听觉反射测试（ART）结果。非肿瘤组的患者经挑选，以匹配肿瘤组中个体患者的听力测定配置。除1例肿瘤患者外，其余所有肿瘤患者的ABR波形均异常，无肿瘤患者中有7例ABR波形异常。25例肿瘤患者的ART结果异常，无肿瘤患者中有2例ART结果异常。ABR结果异常的无肿瘤患者通常比ABR波形正常的无肿瘤患者听力损失更严重。ABR和ART值得继续用于疑似蜗后病变患者的听力检查，但显然，当怀疑有蜗后病变时，还必须考虑听力损失程度和其他医学信息。
