蝶骨嵴脑膜瘤基底部的处理20例分析

目的总结经翼点入路显微手术切除蝶骨嵴脑膜瘤的经验。方法对20例蝶骨嵴脑膜瘤的显微外科手术作回顾性分析。手术入路均为翼点入路，其中蝾骨嵴内1／3者7例。外1／3者13例，术中采取在硬膜外和在硬膜下先处理蝶骨嵴脑膜瘤基底部，阻断肿瘤基底部的血供，然后再在显微镜下行肿瘤切除。结果全切除16例，大部分切除4例，1例术后死亡，术后轻瘫4例，余恢复良好。结论采用翼点入路，熟练掌握术区显微解剖，先处理好肿瘤基底部，可明显减少术中出血，可提高显微镜下全切除肿瘤的切除率，减少术后神经功能障碍。

Treatment the Base of Sphenoid Ridge Meningiomas(The Clinical Data of 20 Cases)

Objective To sum up the experience of treating sphenoid ridge meningiomas By microsurgery via pterional approach. Methods Twenty cases of sphenoid ridge meningiomas were analyzed retrospectively. The surgery was performed via ptertrion apporoah. Seven of the cases were of medial typ tumor, theiteen cases later type tumor, to treat the base of sphenoid meningiomas from epidural and subdural in surgery at first,, to stop the vascular of the base of sphenoid ridge meningioas. Results The tumors were totally resented in 16 cases, subtotally resented in 4 cases, one of then died and 4 cases had hemiplegia. Condusion Pterion approach plus micromanipulation and to treat the base of sphenoid ridge meningiomas at fiest can improve the removal rate of sphenoid ridge meningiomas and reduce postoperative nervousv malfunction.
