目的：分析研究影响脑膜瘤根治的因素。方法：统计分析１８例复发脑膜瘤的复发原因和复发时间。结果：１８例复发脑膜瘤占同期经手术治疗的１８７例脑膜瘤的９６２％。男性６例，女性１２例。复发时间为术后６月～９年，平均２年４月。其中６５％在１～２年复发。全部复发脑膜瘤均行二次手术，全切除１０例，次全切除５例，大部切除３例，无一例死亡及严重并发症。结论：肿瘤部分残留是不能彻底根治的主要原因。若选择合适手术入路、术野宽阔、手术视角扩大，熟练显微外科技术，会减少和消除肿瘤残留，增加脑膜瘤根治。彻底切除肿瘤侵袭或可能侵袭的硬膜、颅骨、静脉窦及脑组织，可避免肿瘤复发，达到真正根治目的 Objective: To analyze and study the factors affecting the cure of meningioma. Methods: Statistical analysis of 18 cases of recurrent meningioma recurrent causes and recurrence time. Results: Eighteen recurrent meningiomas accounted for 962% of 187 meningioma surgically treated in the same period. 6 males and 12 females. The recurrence time was 6 months to 9 years after operation, with an average of 2 years in April. 65% of them recurred in 1 to 2 years. All patients with recurrent meningioma underwent secondary surgery. Total resection was performed in 10 cases, subtotal resection in 5 cases, and partial resection in 3 cases. There was no death or serious complications. Conclusion: Some residual tumor is the main reason that can not be completely cured. If you choose the appropriate surgical approach, broad surgical field, surgical perspective, skilled microsurgery, will reduce and eliminate tumor residues, increase meningioma radical. Complete removal of tumor invasion or possible invasion of the dura, skull, sinus and brain tissue, to avoid recurrence of the tumor, to achieve a real cure
