目的：总结桥小脑角肿瘤的临床特点和治疗体会。方法：回顾性分析本科1996年6月至2004年7月收治桥小脑角肿瘤36例的临床资料。结果：36例桥小脑角肿瘤中,听神经瘤28例,脑膜瘤4例,胆脂瘤3例,血管网状细胞瘤1例。本组均采用单侧枕下乙状窦后入路,运用显微外科技术进行肿瘤切除,结果肿瘤全切除32例,次全切除4例。全组面神经解剖保留32例(89％),功能保留27例(75％),术后永久性面瘫10例。结论：单侧枕下乙状窦后入路显微外科手术适用于不同性质的桥小脑角肿瘤,严格按照显微外科技术操作,肿瘤可全切除,并能有效地保护桥小脑角周围的重要组织结构及其功能。
Objective: To summarize the clinical features and treatment of cerebellopontine angle tumors. Methods: The clinical data of 36 patients with cerebellopontine angle tumors admitted from June 1996 to July 2004 were retrospectively analyzed. Results: In 36 cases of cerebellopontine angle tumors, 28 were acoustic neuromas, 4 were meningioma, 3 were cholesteatoma and 1 was vascular reticular tumor. This group were unilateral suboccipital sigmoid sinus posterior approach, the use of microsurgery for tumor resection, the results of total tumor resection in 32 cases, subtotal resection in 4 cases. All facial nerve anatomy retained 32 cases (89%), function retention in 27 cases (75%), postoperative permanent facial paralysis in 10 cases. CONCLUSIONS: Unilateral suboccipital retrosigmoid posterior approach microsurgery is suitable for the treatment of cerebellopontine angle tumors of different origins. In strict accordance with the microsurgical techniques, the tumors can be resected completely and the lesions around the cerebellopontine angle can be effectively protected Organizational structure and its function.
