用显微外科技术连续切除鞍上与鞍旁区脑膜瘤３８例，术中着生观察了肿瘤附着部位、肿瘤颅底侵犯与颅底外生长、颅内扩展部位及对邻近结构的影响。３１例（８１．６％）获肿瘤全切除，余获次全或大部切除，无死亡。本资料表明，肿瘤直接包裹脑底动脉，侵蚀海绵窦、眶上裂、视神经孔与蝶骨体等结构是影响肿瘤全切除或根治的主要因素。

Thirty-eight cases of meningioma in the suprasellar and parasellar region were excised by microsurgical technique. The location of tumor attachment, the skull base invasion and the extracranial growth, the site of intracranial extension and the adjacent structures were observed during the operation. Thirty-one patients (81.6%) were completely resected by the tumor, and the others were subtotally subtotal or subtotal resection without death. The data show that the tumor directly wrapped the brain artery, cavernous sinus erosion, supraorbital fissure, optic nerve hole and sphenoid body structure is the main factor affecting tumor resection or radical.
