显微手术切除大型桥小脑角肿瘤

目的探讨应用显微手术切除大型桥小脑角肿瘤的临床疗效与并发症。方法采用显微手术技巧切除大型桥小脑角肿瘤22例（其中听神经瘤11例，脑膜瘤8例，三叉神经瘤2例，胆脂瘤1例），并就临床结果进行分析。结果11例听神经瘤全切8例，次全切3例；8例脑膜瘤全切5例，次全切2例，部分切除1例；2例三叉神经瘤均次全切除；1例胆脂瘤全切。术后脑出血再次手术后死亡1例。结论大型桥小脑角肿瘤手术具挑战性，良好的显微手术技巧能提高全切率、减少并发症。

Microsurgical resection of large cerebellopontine angle tumor

Objective To discuss the clinical effectiveness and complications of microsurgical resection of cerebellopontine angle tumor. Methods We applied microsurgical operations to 22 largc cerebellopontine angle tumors (include 11 acoustic neurinomas ,8 meningiomas ,2 trigeminal tumors and 1 cholesteatoma)and analyzed t0he clinical results. Results 8 cases received total resection and 3 cases received subtotal resection within the 11 acoustic neurinomas. 5 cases received total resection,2 cases received subtotal resection and 1 case received partial resection within the 8 meningiomas. Both of the 2 trigeminal tumors received subtotal resection.1 cerebral hemorrhage dead after re-operation. Conclusion Microsurgical operation of large cerebellopontine angle tumor is challenging. Professional microsurgical techniques can improve total resection ratio and reduce the incidence of complications.
