为探讨并总结锁孔显微手术治疗颅底脑膜瘤的方法和经验,回顾性总结经锁孔显微手术治疗111例各个不同部位的颅底脑膜瘤,其中经额眉上或眉间上额纹切口切除双侧颅前窝底脑膜瘤25例,鞍区脑膜瘤(含鞍结节、前床突及鞍隔)23例;经额下或翼点入路切除蝶骨嵴脑膜瘤8例;经乙状窦后入路切除岩斜区脑膜瘤11例和脑桥小脑角脑膜瘤18例;经改良的乙状窦前-锁孔入路显微手术切除岩斜区脑膜瘤7例。15例小脑幕脑膜瘤和4例镰幕区脑膜瘤,经相应部位开颅切除。全切除肿瘤104例,次全切除7例,无死亡。结论:锁孔显微手术是切除颅底脑膜瘤的一种损伤小和效果好的方法。
To explore and summarize the methods and experience of keyhole microsurgery in the treatment of skull base meningioma, retrospective review of 111 cases of skull base meningiomas by keyhole microsurgery in different parts of the skull base meningiomas, Side of the skull anterior fundus meningioma in 25 cases, the sellar meningioma (including saddle nodules, anterior bed process and septum) in 23 cases; by the amount of pterional approach or pterional approach to remove sphenoid ridge meningioma in 8 cases; 11 cases of petroclival meningioma and 18 cases of cerebellopontine angle meningiomas were excised by sinus approach. Seven cases of petroclival meningiomas were excised microsurgically by modified sigmoid sinus anterior keyhole approach. Fifteen cases of cerebellar meningiomas and four cases of meningiomas were removed by craniotomy. Total resection of the tumor in 104 cases, subtotal resection in 7 cases, no death. Conclusion: Keyhole microsurgery is a less invasive and effective method for resection of skull base meningioma.
