Abstract: Objective　 To study the effect of vertebral canal reconstruction with micro titanium plate after multi-cervical segments Intramedullary tumor resection. Methods The enbloc laminectomy was performed by Tomita method in the 24 cases with multi-cervical segments intramedullary tumor. Among them, 7 cases resected laminae were re-implantation with micro titanium plate fixation. The vertebral canal were reconstructed and spinal stabilities were kept. Results No vertebral canal stegnosis, kyphosis and spine unstability were found after laminal re-implantation and vertebral canal plasty. However, the kyphosis, respiratory disturbance, sphincter dysfunction, cerebral spinal fluid leakage associated with intraeranial infection and epidural hydrops were in 5,2,5,5 and 3 cases respectively without laminae re-implantation and vertebral canal plasty.Conclusion After Tomita enbloc laminectomy, micro titanium plate fixed laminae re-implantation has keeping postoperative spinal stability for treatment of the patients with multi-cervical segmental intramedullary tumor and it would reduce the occurrence of postoperative complication.

摘要： 目的 探讨微型钛板重建椎管方法在多节段髓内肿瘤切除术后应用的优点。方法 多节段髓内肿瘤24例，均采用桐田法切除整块椎板，其中7例以微型钛板固定回植已切除的椎板，椎管成形，重建脊柱稳定性。结果 经回植椎板行椎管成形的病人没有发现椎管狭窄、脊柱后突及不稳；未经回植椎板椎管成形病人中有5例出现脊柱后突畸形，2例出现呼吸障碍，5例出现括约肌功能障碍，5例出现脑脊液漏合并颅内感染，3例出现硬膜外积液。结论 应用桐田法切除整块椎板后微型钛板固定椎板回植法对多节段髓内肿瘤切除术病人术后脊柱的稳定性意义重大，能减少术后并发症的发生。
