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。
Objective To investigate the classification and efficacy of medial sphenoid ridge meningioma. Methods The classification, microsurgery and prognosis of 48 cases of medial sphenoid ridge meningioma were retrospectively analyzed. Results All patients underwent microsurgical resection of the tumor. Simpson Ⅰ resection in 6 cases, Simpson Ⅱ resection in 27 cases, Simpson Ⅲ resection in 15 cases. Postoperative visual acuity was significantly improved in 20 cases, 6 cases of visual acuity was not obvious, 2 cases of ipsilateral visual acuity decreased. 4 died (8.3%). The patients were followed up for an average of 3.5 years. Nine patients (18.75%) had tumor recurrence during follow-up. Conclusions Type I and type II tumors have a high rate of full resection while type III tumors have a low rate of full resection. Using microsurgical techniques to adequately protect the optic nerve, internal carotid artery and its branches can improve tumor resection rate and efficacy.
