前庭神经鞘瘤手术次常见的并发症是脑脊液(CSF)漏 ,其最常见的路线是通过咽鼓管进入鼻咽。为避免这种并发症 ,常规的方法是行中耳和咽鼓管填塞 ,可将 CSF漏的发生率从 13%减少至 1.6 %。本研究目的在于阐明经迷路前庭神经瘤切除术后病人的长期中耳状态。 14例经迷路前庭神经鞘 The most common complication of vestibular schwannoma surgery is cerebrospinal fluid (CSF) leakage, the most common route of which is through the eustachian tube into the nasopharynx. To avoid this complication, the usual procedure is to cuff the middle ear and Eustachian tube and reduce the incidence of CSF leakage from 13% to 1.6%. The aim of this study was to elucidate the long-term middle ear state of patients after excision of the vestibular neuroma. Fourteen cases were lost through the vestibular sheath
