经硬膜外入路切除海绵窦肿瘤(附18例报告)

目的 报告１８例海绵窦肿瘤的经硬膜外入路显微外科治疗的经济。方法 回顾性分析自１９９４￣１９９８年８月经硬膜外入路切除１８例海绵窦肿瘤的临床及影像学特征、手术方法、手术结果及手术并发症等。结果 全部肿瘤全切除,无手术死亡,术后４５％颅神经症状得到改善,４５％颅神经症状同术前,１０％颅神经症状加重,１１％术后出现新颅神经症状。随访２月至４８月（平均２４月）无复发。结论 海绵窦肿瘤可采用单一硬膜外入路

Trans-epiduralapproach for cavernous sinus tumors

Objective To discuss the trans epidural microsurgical treatment of 18 cases with tumor in cavernous sinus. Methods A retrospective review of the clinical material preoperative CT and MRI features, operative techniques, result of operation and postoperative complications of 18 cases with tumor in cavernous sinus which was treated via epidural approach during 1994 to 1998 was done. Results Total resection of the tumor was achieved in all cases, no patient died in this series. 45 percent of cranid nerves (CNs) deficit was improved, 45 percent of CNs symptoums did not change, and 10 percent of CNs palsies worsened. 11 percent of patients had new CNs deficit after operation. There was no recurrence of tumors during the follow up period of 2 to 48 months(average 24 months). Conclusions The tumors in cavernous sinus can be totally resected by epidural approach alone. Understanding of the microanatomy about this approach can greatly reduce postoperative morbidity of patients.
