目的：对23例蝶鞍及其邻近区域脑膜瘤应用显微外科技术治疗的结果进行分析。方法：根据脑膜瘤起源部位及其主体所在位置的不同，采用不同的手术入路，应用显微外科技术切除肿瘤。结果：全组蝶鞍及其邻近区域脑膜瘤23例，鞍上型11例，鞍旁型12例，其中20例（86.96％）获全切除，无死亡，全组术后Karnofsky计分90．43±14．29分，较术前平均提高30．87土12．67分（P＜0．001），术后平均住院时间15．5±7．5天。结论：提高疗效的关键在于设计合理的手术入路与娴熟的显微外科技术。鞍旁脑膜瘤首选眶颧额颞下入路，大型或巨大型鞍上脑膜瘤首选眶额入路。
Objective: To analyze the results of microsurgical treatment of 23 cases of sella and its adjacent area meningioma. Methods: According to the different location of the origin of meningioma and its main body, different surgical approaches were used to remove the tumor using microsurgical techniques. Results: Twenty-three cases of meningioma, 11 cases of suprasellar sellae and 12 cases of mesencephalic sellae were found in the entire group of sella and its adjacent area. Twenty cases (86.96%) underwent total resection without death, and Karnofsky score was 90 after operation. 43 ± 14.29 points, an increase of 30.87 ± 12.67 points (P <0.001) compared with the preoperative average. The average postoperative hospital stay was 15.5 ± 7.5 days. Conclusion: The key to improving the efficacy is to design a reasonable surgical approach and skilled microsurgical techniques. Parasellar meningioma Frontal orbital frontotemporal approach, large or large suprasellar meningioma orbitofrontal approach.
