目的 :探索鞍区脑膜瘤的显微手术方法和治疗效果。方法 :总结近十年来采用显微技术治疗 2 6例鞍区脑膜瘤的临床资料。结果 :按Simpson手术分类 :1类 2例 ,2类 1 2例 ,3类 1 2例。术后死亡 1例。2 5例患者随访 2～ 1 0年 ,肿瘤复发死亡 1例 ,再次手术 1例 ,生活自理 4例 ,恢复工作 1 9例。结论 :对鞍区脑膜瘤 ,应在避免损伤正常结构前提下尽量切除肿瘤 ,采用膜内分块切除方法能最大程度地减少损伤周围结构 Objective: To explore the microsurgical methods and therapeutic effects of sellar meningiomas. Methods: To summarize the clinical data of 26 cases of sellar meningioma treated by microsurgical techniques in recent ten years. Results: According to the Simpson classification, there were 1 case in 2 cases, 2 cases in 12 cases and 3 cases in 12 cases. One patient died after operation. Twenty-five patients were followed up for 2 to 10 years. There were 1 tumor recurrence, 1 reoperation, 4 self-care and 19 reinstatement. Conclusion: For the sellar meningiomas, the tumor should be removed as far as possible without damaging the normal structure. The intra-membrane sub-block excision method can minimize the damage surrounding structures
