侵犯鼻窦的前颅窝底脑膜瘤术中脑脊液漏的预防

目的:介绍侵犯颅底骨质及鼻窦的前颅窝底脑膜瘤的手术方法及颅底重建经验。方法:回顾性分析13例患者的临床资料。大冠状或小冠状皮瓣开颅,骨膜向前完整分离,分块切除肿瘤后,咬除或磨除颅底受侵蚀及增生的骨质,将突入鼻窦内的肿瘤切除。切取患者下腹部合适大小的脂肪组织,修剪后填塞入颅骨缺损处,将额骨骨膜翻下,严密缝合骨膜和颅底缺损处周边正常硬膜,用耳脑胶在缝合处粘合一圈。结果:按照Simpson标准,12例Ⅰ级切除,1例Ⅱ级切除。术后并发症包括无菌性脑膜炎3例,额叶症状包括多语、躁动、欣快及缄默3例,无脑脊液漏及颅内感染,无死亡。病理诊断均为良性脑膜瘤,其中2例为细胞增生活跃。随访9个月～8年,平均3.4年,肿瘤无复发。结论:脂肪填塞颅底缺损处,带蒂骨膜与缺损周边正常硬膜严密缝合,用生物胶加固缝合处能有效防止脑脊液漏。

The prevention cerebrospinal fluid leakage during operating anterior skull base meningioma involving paranasal sinuses

Objective:To introduce a kind of method for skull base reconstruction after resecting anterior skull base tumors involving paranasal sinuses.Method:A retrospective analysis was carried out on 13 patients who underwent anterior skull base reconstruction.Pericranial flap were detached with integrity from the frontal bone during craniotomy,after the tumor had been resected partitionedly,the cribriform plate of ethmoid bone which was involved by tumor was resected.Using the fat tissue to fill the skull-base def...
