目的探讨经半椎板入路切除椎管内神经鞘瘤的应用价值。方法采用一侧半椎板入路显微切除椎管内神经鞘瘤22例,其中肿瘤位于颈段10例,胸段7例,腰段5例。结果所有患者肿瘤均被全切除,术后症状明显改善,随访期间未见新的神经功能损害或脊柱畸形并发症。结论半椎板入路显微手术切除椎管内神经鞘瘤具有手术创伤小、恢复快且有利于维持脊柱稳定性的优点,适用于治疗位于侧面或侧背面生长的神经鞘瘤。
Objective To investigate the clinical value of resection of schwannoma in the spinal canal by semi-laminar approach. Methods Twenty-two patients with schwannoma in the spinal canal were treated with one-sided hemilaminectomy. The tumors were located in 10 cases of cervical segment, 7 cases of thoracic segment and 5 cases of lumbar segment. Results All patients underwent total resection of the tumor and postoperative symptoms were significantly improved. No new neurologic impairment or complications of spinal deformity were observed during follow-up. Conclusions The microsurgical removal of spinal schwannoma by the semi-laminar approach has the advantages of less trauma, faster recovery and more favorable spinal stability. It is suitable for the treatment of schwannoma located on the lateral or lateral dorsal surface.
