早期诊断和外科技术的改进,改善了听神经瘤的手术预后。由于电生理学的筛选试验和准确的放射学方法,使得准确诊断较小的听神经瘤成为可能。大多数听神经瘤病例,可先出现听觉系统症状,耳鸣是最早期的症状,小部分可先出现前庭症状,听力评估应是最基本的筛选项目,许多阈上听力试验已被广泛应用,据称有诊断价值。听脑干反应(ABR)试验对 Early diagnosis and surgical techniques improve the prognosis of acoustic neuroma surgery. Because of electrophysiological screening tests and accurate radiological methods, it is possible to accurately diagnose smaller acoustic neuromas. Most acoustic neuroma cases, the first auditory system may appear symptoms, tinnitus is the earliest symptoms, a small part of the forebrain symptoms may appear, the hearing assessment should be the most basic screening items, many threshold hearing tests have been widely used, it is reported Diagnostic value.
