Microsurgical Treatment of Tuberculum Sellae Meningioma

目的探讨显微外科手术治疗鞍结节脑膜瘤的方法及效果。方法回顾性分析自2003年6月至2006年10月显微手术治疗的38例鞍结节脑膜瘤。结果SimpsonⅠ级切除23例,Ⅱ级切除12例,Ⅲ级切除3例。术后视力损害和视野缺损均有不同程度恢复18例,12例视力无改变,2例视力下降。2例术后出现不同程度的尿崩,经相应治疗后在7天内好转。无死亡病例。结论选择恰当的手术入路,应用显微神经外科手术治疗鞍结节脑膜瘤,肿瘤全切除率高,术后并发症少,视觉症状恢复率高,疗效满意。

Objective： To investigate the methods of microsurgical treatment and their operative effect on the tuberculum sellae meningiomas. Methods： A retrospective analysis of 38 cases with tuberculum sellae meningiomas treated micmsurgically was performed from 2003.6 to 2006. 10. Results： According to the Simpson classification, Simpson Grade Ⅰ resection was achived in 23 cases, Simpson Grade Ⅱ resection in 12 cases, Simpson Grade m resection in 3 cases.
