摘要
内听道位于岩骨深部,其中走行位听神经和面神经,所涉及的病变多与这些颅神经有关。内听道开口于小脑桥脑角区、止于内听道底,与脑干、小脑、内耳的前庭和耳蜗相毗邻,手术解剖复杂。作者报告自1989年～1991年采用经颞骨途径行内听道手术15例,其中经迷路上进路12例,经乳突迷路进路3例。所行手术包括颞骨纵行骨折面神经麻痹3例,贝尔氏面瘫4例,耳带状疱疹1例,均行面神经全程减压,颞骨原发性胆脂瘤2例,面神经鞘瘤2例,肿瘤切除后行面神经移植吻合;内听道听神经瘤3例。本文仅就手术技术及随访结果进行讨论。
Lesions located in the internal auditory canal were previously considered surgica-lly inaccessible before the development of the transtemporal approaches by House in1960s. Since then, these techniques have been widely used in the world. Suprisinglythere were only few reports in Chinese literature. Here with 15 cases of internal au-titory canal microsurgeries were reported, including total decompression of the facialnerve for facial paralysis resulted from temporal boue fracture, Bell's palsy, herpeszoster oticus, and removal of primary cholesteatoma, facial neuroma and acousticneuroma. Two main sub-approaches were adopted in the series, transtemporal suprala-byrinthine, in 12 patients, and translabyinthine in 3 patients. The surgical procedurewith some modifications was described. No serious complications occurred in thisgroup. An average 10 month follow-up was made with good results.
