蝶骨嵴脑膜瘤约占幕上脑膜瘤的1/5,其中约1/2为内侧型蝶骨嵴脑膜瘤[1]。内侧型蝶骨嵴脑膜瘤位置深在,与颈内动脉、大脑中动脉、视神经及海绵窦关系密切,手术全切难度大,并发症多,是颅底外科的难题之一。我科近5年来采用Yasargil翼点入路对16例内侧型蝶骨嵴脑膜瘤进行显微外科切 Sphenoid ridge meningioma accounted for about 1/5 of supratentorial meningioma, of which about 1/2 of the medial sphenoid ridge meningioma [1]. Medial sphenoid ridge meningioma deep in position, and the internal carotid artery, middle cerebral artery, optic nerve and cavernous sinus are closely related to the operation of the whole cut difficult, complications, skull base surgery is one of the problems. In recent 5 years, our department has adopted Yasargil pterional approach for the microsurgical cutting of 16 cases of medial sphenoid ridge meningiomas
