Although unilateral hearing loss is often the initial sign of vestibular schwannoma (VS), the pathogenesis of the associated structures within the cerebellopontine angle can result in vestibular, facial, or vascular symptoms. Removal of a VS causes deficits in hearing, balance, and gaze stability. The resulting hearing loss eliminates the benefits of binaural listening that provide localization, loudness summation, and listening-in-noise ability. Reduced balance and gaze stability increase fall risk. This review discusses modern treatment options for auditory and vestibular rehabilitation including contralateral routing of signals (CROS), bilateral CROS, bone-anchored implants, tinnitus management, gaze and gait stability exercises.
虽然单侧听力损失通常是前庭神经鞘瘤（VS）的初始症状，但小脑脑桥角内相关结构的发病机制可导致前庭、面部或血管症状。切除VS会导致听力、平衡和注视稳定性方面的缺陷。由此产生的听力损失消除了双耳聆听的益处，双耳聆听可提供定位、响度总和和噪声中聆听的能力。平衡和注视稳定性的降低增加了跌倒风险。本综述讨论了听觉和前庭康复的现代治疗选择，包括信号对侧路由（CROS）、双侧CROS、骨锚式植入物、耳鸣管理、注视和步态稳定性锻炼。
