蝶骨嵴内侧型脑膜瘤的显微手术治疗

目的：探讨蝶骨嵴内侧型脑膜瘤的手术方法．方法：通过收集2000-01～2008-06手术治疗的29例蝶骨嵴内侧型脑膜瘤患者．采用翼点为中心的颞额入路．对手术方法和效果进行分析总结．结果：全部病例均通过显微手术方法切除．全切除21例，次全切除8例．术后并发尿崩2例，经术后治疗，痊愈；动眼神经麻痹2例．经治疗，1例1个月后恢复，1例未恢复；视力恢复12例，好转7例，无恢复或加重2例．死亡1例，死亡原因为血管痉挛大面积脑梗塞．结论：通过显微手术治疗蝶骨嵴内侧型脑膜瘤，能够最大限度保护神经、血管及重要脑组织，提高肿瘤全切率及手术疗效．

Microsurgical Techniques for Medial Sphenoidal Ridge Meningioma

Objective：To discuss the microsurgical techniques to treat medial sphenoidal ridge meningioma.Methods：The operative procedure and effect for 29 cases of this disease hospitalized from January 2000 to June 2008,treated with temporofrontal operative approach centred round pterion,were analyzed and summarized.Results：All meningiomas were removed with microsurgery. Total resection was performed on 21 cases,and subtotal resection performed on 8 cases.Postoperative diabetes insipidus happened to 2 patients but was cured.Postoperative oculomotor paralysis occurred in 2 patients,and one was cured and the other was not.Vision of 12 patients returned to normal and improved in 7 patients.No change or deterioration for vision happened to 2 patients.1 patient died of extensive cerebral infarction because of cerebrovascular spasm.Conclusion：Treating medial sphenoidal ridge meningioma with microsurgery can improve tumorous total resection and curative effect while protecting cranial nerves,blood vessels and brain tissue.
