内侧型蝶骨嵴脑膜瘤的显微外科手术治疗

目的探讨内侧型蝶骨嵴脑膜瘤的分型和疗效。方法回顾性分析48例内侧型蝶骨嵴脑膜瘤的分型、显微手术及其预后。结果所有患者均通过显微外科技术切除肿瘤。SimpsonⅠ级切除6例,SimpsonⅡ级切除27例,SimpsonⅢ级切除15例。术后视力明显改善20例,6例视力改变不明显,2例出现患侧视力下降。死亡4例(8.3%)。平均随访3.5年,随访期间肿瘤复发9例(18.75%)。结论Ⅰ型和Ⅱ型肿瘤全切率较高,而Ⅲ型肿瘤全切率较低;利用显微外科技术充分保护视神经、颈内动脉及其分支,能够提高肿瘤全切率和疗效。

Microsurgical treatment for medial sphenoid wing meningiomas

Objective To explore the classification and effectiveness of microsurgical resection of medial sphenoid wing meningiomas.Methods Forty-eight patients with medial sphenoid wing meningiomas were retrospectively reviewed in the classification of meningiomas,microsurgery,and prognosis.Results All meningiomas were resected with microsurgical treatment.Among them,Simpson grade Ⅰ was resected in 6 patients,grade Ⅱ in 27,and grade Ⅲ in 15.After operation,there were 20 patients with visual improvement,6 without significant visual improvement,and 2 with visual decline.4(8.3%) patients died.9(18.75%) cases recurred during a mean follow-up period of 3.5 years.Conclusions Total resection can be achieved in most Type Ⅰ and Type Ⅱ,but in a minority of Type Ⅲ.Making full use of microsargical techniques in preservation of the optic nerve and internal carotid and its perforators can increase the effectiveness of operation.
