目的探讨鞍结节脑膜瘤显微外科解剖和手术技巧。方法回顾分析了自1999年6月至2005年12月间经手术和病理证实的22例鞍结节脑膜瘤,手术采用额下入路7例、翼点入路6例、额下和翼点联合入路9例。结果按Simpson分级:I为6例,II级为13例,共占86%,III级为3例,术后视力改善的有12例21眼,无改变的为7例12眼,3例4眼视力较术前下降。结论手术切除是最有效的治疗方法,熟悉鞍区的解剖并具备娴熟的显微外科操作技术,是手术成功的关键。
Objective To investigate the microsurgical anatomy and surgical technique of sella nodular meningiomas. Methods A retrospective analysis of 22 cases of saddle nodular meningiomas confirmed by surgery and pathology from June 1999 to December 2005 was performed in 7 cases with inferior frontal approach and 6 cases with pterional approach. Joint approach in 9 cases. The results were classified according to Simpson classification: I was 6 cases, II grade was 13 cases, accounting for 86%, III grade 3 cases, postoperative visual acuity improved in 12 cases 21 cases, unchanged in 7 cases 12 eyes, 3 cases 4 Visual acuity decreased compared with preoperative. Conclusions Surgical resection is the most effective treatment method. Being familiar with the anatomy of the saddle area and having the skill of microsurgical operation is the key to successful operation.
