双额底前纵裂入路显微切除巨大型鞍结节脑膜瘤

目的 总结经双额底前纵裂入路切除巨大型鞍结节脑膜瘤的显微手术技巧.方法 回顾2005年1月至2009年11月期间我院收治的11例鞍区巨大脑膜瘤患者的临床资料,分析经双额底前纵裂入路的手术要点和可能影响预后的因素.结果 Simpson Ⅰ级切除者5例,其余均Ⅱ级切除;无手术死亡.术后视力改善9例,视力无变化1例,视力恶化1例;术后短暂性轻度尿崩5例.术后视力恢复不理想均为术前双侧视力显著下降且病程超过3年者.结论 鞍结节脑膜瘤经双额底前纵裂入路对鞍背和三脑室下部、海绵窦均有良好暴露.术中严格遵循先断肿瘤基底或离断基底大部后再在肿瘤与周围神经、血管之间的潜在蛛网膜间隙、蛛网膜束带分离切除肿瘤是提高全切率、减少术后并发症的关键.
