单侧椎板多点开窗治疗椎管内神经鞘瘤14例

Treatment of 14 intraspinal schwannomas with multi-point hemilaminectomy

目的探讨单侧椎板多点开窗在椎管内大型神经鞘瘤显微外科手术中的应用。方法回顾性分析2003年1月-2008年12月采用单侧椎板多点开窗显微外科手术治疗的14例椎管内大型神经鞘瘤的临床资料。结果14例行肿瘤完全切除术,术后3d可下床活动,随访6-36个月,症状和体征消失或明显改善,无肿瘤复发或脊椎不稳定。结论单侧椎板多点开窗显微外科手术治疗椎管内大型神经鞘瘤最大程度保留脊柱后部肌肉、韧带和骨结构,有利于脊柱的稳定性,具有安全、损伤小、手术时间短、术后恢复快等优点。

Objective To explore the application of multi-point hemilaminectomy in microsurgical treatment of large intraspinal schwannoma.Methods Clinical data about 14 large intraspinal schwannomas undergone multi-point hemilaminectomy in January 2003-December 2008 were retrospectively analyzed.Results All the 14 large intraspinal schwannomas were completely removed.The patients could move about 3 days after operation and were followed up for 6-36 months during which symptoms and signs disappeared or significantly improved.No recurrence or spinal abnormality occurred.Conclusion Treatment of large intraspinal schwannoma with multi-point hemilaminectomy can reserve muscles,ligaments and bone structures at the back of spinal cord at the greatest extant with many advantages including minimal trauma,operative safety and rapid recovery,thus contributing to spinal stability.
