摘要:

目的 探讨内侧型蝶骨嵴脑膜瘤的显微手术技巧。方法 回顾性分析19例显微外科手术治疗的内侧型蝶骨嵴脑膜瘤的临床资料，所有病例均经翼点入路或扩大的翼点入路进行肿瘤切除，其中肿瘤全切除16例，次全切除2例，部分切除1例。观察术后疗效。结果 19例术后随访4个月~70月，预后优良16例，一般2例，差1例，无复发病例。结论 术前完善的神经影像学评估，认真的分析影像学资料，术中准确的判断肿瘤包裹的动脉和穿支血管的走行，良好的显微外科技术和手术分离技巧，是提高手术全切率，减少术后并发症的关键。

Abstract:

Objective To explore the microsurgical techniques for medial sphenoid ridge meningioma. Methods A retrospective analysis was performed on 19 patients with medial sphenoid ridge meningioma treated by microsurgery. All patients underwent tumor resection via pterional approach or enlarged pterion approach. Results Among the 19 patients with medial sphenoid ridge meningioma, 16 underwent total resection of the tumor, 2 subtotal and 1 partial resection. All patients were followed up for 4 months to 70 months. The prognosis was excellent in 16 cases, good in 2 cases, and poor in 1 case. No recurrence was observed. Conclusion The preoperative neuroimaging assessment, careful analysis of imaging data, accurate judgment of tumor-wrapped arteries and perforator blood vessels during surgery, good microsurgical techniques and surgical separation techniques, are the keys to improve the surgical success rate and reduce postoperative complications. Patients receiving total tumor resection could have a more favorable prognosis.
