Hemifacial spasm (HFS) is a rare presentation of vestibular schwannoma. The authors present their experience with a 27-year-old woman who presented with normal hearing and HFS, which was the single neurological manifestation of an 18-mm vestibular schwannoma. In this challenging situation, the treatment goals were maximal tumor removal with preservation of hearing and facial nerve function and cure of the HFS. The authors achieved these goals, performing complete tumor removal via a retrosigmoid approach, assisted with neurophysiological monitoring and a 45°-angle QEVO endoscope. In the video, they explain the clinical, radiological, and surgical considerations and demonstrate the surgical technique.

半面痉挛（HFS）是前庭神经鞘瘤的一种罕见表现。作者介绍了他们对一名27岁女性的治疗经验，该患者听力正常但患有半面痉挛，这是一个18毫米前庭神经鞘瘤的唯一神经学表现。在这种具有挑战性的情况下，治疗目标是在保留听力和面神经功能的同时最大限度地切除肿瘤并治愈半面痉挛。作者通过乙状窦后入路，在神经生理监测和45°角QEVO内窥镜辅助下实现了完全肿瘤切除，从而达成了这些目标。在视频中，他们解释了临床、放射学和手术方面的考虑因素，并展示了手术技术。视频可在此处找到：https://stream.cadmore.media/r10.3171/2021.7.FOCVID2099 。
