目的:探讨显微手术切除岩斜区脑膜瘤的手术方法及术后疗效,总结临床治疗经验。方法:通过回顾分析我科1997年8月~2006年3月经显微切除19例岩斜区脑膜瘤的临床资料,主要采用岩骨乙状窦前入路、颞下经小脑幕入路、乙状窦后入路3种入路。结果:肿瘤全切除12例(63.2%),5例次全切,2例大部分切除,均无严重并发症发生。结论:术前充分准备、选择合适的手术入路和娴熟显微外科技术可以提高岩斜坡区脑膜瘤的切除率,减少并发症的发生,降低病死率。
Objective: To investigate the surgical methods and postoperative effects of microsurgical removal of petroclival meningioma and to summarize the experience of clinical treatment. Methods: The clinical data of 19 patients with petroclival meningiomas underwent microdissection from August 1997 to March 2006 were retrospectively analyzed. The main data were petrous ostium anterior approach, inferior temporal approach, Sinus retrograde approach 3 kinds of approach. Results: Total resection in 12 cases (63.2%), 5 cases subtotal resection, 2 cases of most resections, no serious complications. Conclusion: The adequate preoperative preparation, appropriate surgical approach and skilled microsurgical techniques can increase the resection rate of meningiomas in rock slopes, reduce the incidence of complications and reduce the mortality.
