摘　　要：目的总结小脑幕脑膜瘤的手术治疗经验。方法回顾性分析72例小脑幕脑膜瘤病人的临床资料,比较和总结不同类型肿瘤的手术治疗特点。结果SimpsonⅠ级切除15例,Ⅱ级切除50例,Ⅳ级切除7例。静脉窦受累率为51.4%。术后并发症发生率为19.4%,病死率为2.8%。术后随访54例,平均62.7个月;肿瘤复发3例。结论应根据肿瘤位置和扩展方向选择手术入路,肿瘤侵蚀静脉窦或与脑干、深静脉及脑神经紧密黏连,是影响手术全切除的因素。多数病人预后良好。Objective To summarize the experience with surgical treatment for tentorial meningiomas. Methods Seventy-two patients with tentorial rneningiomas were relrospoctively analyzed. The surgical characteristics were summarized and compared between different kinds of tumor. Results Simpson Grade I resection was achieved in 15 patients, Grade II in 50, and Grade IV in 7. Dural sinus was involved in 51.4% of the patients. The postoperative complication rate was 19.4% and mortality 2.8%. The follow-up was available in 54 patients for mean 62.7 months, with a finding of three relapsed tumors. Conclusion The surgical approach should be based on the location and expanding direction of tumors. Total resection is difficult to achieve if the tumor invades a dural sinus or if the tumor closely adheres to the brain stem, deep veins or cranial nerves. Most of patients have a good prognosis.
