目的探讨大型鞍结节脑膜瘤经额外侧入路显微切除的疗效。方法 2006年6月至2010年10月采用额外侧入路共对21例大型鞍结节脑膜瘤进行显微手术切除,随访观察比较手术前后神经功能变化情况。结果 SimpsonⅠ、Ⅱ级切除肿瘤18例(85.7%),SimpsonⅢ级切除肿瘤3例(14.3%),术后视力障碍改善率为86%。结论额外侧入路显微切除大型鞍结节肿瘤,暴露充分、安全可靠,可获得显著疗效。
Objective To investigate the effect of microsurgical removal of large saddle nodular meningioma by extra lateral approach. Methods From June 2006 to October 2010, 21 cases of large saddle nodular meningioma were removed by extra lateral approach. The changes of neurological function before and after operation were observed and compared. Results There were 18 cases (85.7%) of Simpson Ⅰ and Ⅱ resections and 3 cases of Simpson Ⅲ resection (14.3%). The improvement rate of postoperative visual acuity was 86%. Conclusions Extra lateral approach for the microsurgical removal of large saddle nodular tumors with adequate exposure, safety and reliability can achieve significant results.
