半椎板切除显微手术治疗颈椎管内髓外肿瘤

Semi-laminectomy Procedures for the Management of Intradural Extramedullary Tumors of the Cervical Spinal Canal

目的:探讨半椎板切除入路显微手术治疗颈椎管内髓外肿瘤的优缺点。方法:回顾分析了15例采用半椎板切除入路显微手术治疗颈椎管内髓外肿瘤的临床资料。结果:4例哑铃型神经鞘膜瘤椎管外残留部分肿瘤,其他11例均完全切除肿瘤。无一例出现新的神经功能损伤及严重并发症。所有患者在术后早期恢复活动及工作。结论:半椎板切除入路显微手术治疗颈椎管内髓外肿瘤具有损伤小、并发症少,且不影响脊柱的稳定性的优点,有利于患者尽快恢复。

Objective：To study the feasibility of minimally invasion procedure for the management of intradural extramedullary tumors of the cervical spinal canal.Methods：Retrospective analysis of 15 cases of intradural extramedullary tumors of the cervical spinal canal was treated by the approach of semi-laminectomy.Results：Among the 15 cases,including ten cases of neurilemmoma,two cases of neurofibroma,and three cases of meningioma,four of dumbbell neurilemmomas underwent subtotal resection whereas other eleven cases of tumors were totally resections.None of new neurological disfunctions has been found in all cases after the operation as well as recurrence or complications.Conclusion：Semi-laminectomy for the removal of intradural extramedullary tumors of the cervical spinal canal is a mini-invasive procedure,and is beneficial to the stability of spine,with the advantages of short hospitalization time,slight postoperative reactions and fewer complications.
