In 95 percent of the cases, patients with acoustic neuromas will have some magnitude of hearing loss in the affected ear. This paper reports on four patients who had acoustic neuromas and normal hearing. Results from the case history, audiometric evaluation, auditory brainstem response (ABR), electroneurography (ENOG), and vestibular evaluation are reported for each patient. For all patients, the presence of unilateral tinnitus was the most common complaint. Audiologically, elevated or absent acoustic reflex thresholds and abnormal ABR findings were the most powerful diagnostic tools.
在95%的病例中，听神经瘤患者患侧耳朵会有一定程度的听力损失。本文报告了4例患有听神经瘤但听力正常的患者。报告了每位患者的病史、听力测定评估、听觉脑干反应（ABR）、神经电图（ENOG）和前庭评估结果。所有患者中，最常见的主诉是单侧耳鸣。在听力方面，听觉反射阈值升高或缺失以及ABR检查结果异常是最有效的诊断工具。
