经单侧椎板"微孔"入路椎管内原发肿瘤的显微切除

目的 探讨椎管内原发肿瘤的微创治疗与脊柱功能保护的关系。方法 24例椎管内原发肿瘤位于颈段、胸段、腰段硬膜内或硬膜外腔，直径为0．9～3．0cm。精确定位下，根据肿瘤位置和大小情况，用磨钻磨开单侧椎板形成“微孔”，经此入路用显微手术全切除肿瘤。结果 经手术切除以及术后病理证实，神经纤维瘤、神经鞘瘤、脊膜瘤分别为9例、12例、3例，肿瘤全切除。术后3d均可转身运动，术后1周鼓励下床；无需要颈托、腰围等保护。术后3个月MR检查未见肿瘤残存或复发；随访6个月CT检查未见脊柱骨性结构变形。结论 单侧椎板“微孔”入路手术切除肿瘤彻底，是椎管内原发肿瘤的一种疗效较好的微创治疗方法。

Microinvasive therapy for intraspinal tumors resection via Key-hole on mono-lamina

Objective To research the microinvasive therapy for intraspinal tumors resection and study the ways for spinal function protection. Methods Twenty-four cases were detected by MR. The intraspinal tumors located variously and the size of them ranging from 0.9 cm to 3.0 cm. All the tumors underwent resection via Key-hole on mono-lamina and the clinical data were analyzed. Results After tumor pathological examination,the cases of neurofibroma,neurinoma,and spinal meningioma were 9,12 and 3 cases. respectively. All the patient recovered and they walked within one week after operation. No recurrenced on MR examination after 3 months and no spinal tube destruction on CT examination after 6 months. Conclusion The microinvasive therapy via Key-hole on mono-lamina is benefic to the totally resection of intraspinal tumors and also benific to the spinal function protection.
