环枕区及颈段椎管哑铃形肿瘤的显微外科治疗

目的 探讨环枕区及颈段椎管哑铃形肿瘤的手术方法。方法 对经改良枕下远外侧入路和颈后中线入路手术治疗的26例环枕区及颈段椎管哑铃形肿瘤病人的临床资料进行回顾性分析。结果 肿瘤一期全切除23例，次全切除3例，无手术死亡。随访1—9年，所有患者均恢复良好，1例脊索瘤次全切除术后2年复发。结论 经改良枕下远外侧入路和颈后中线入路手术是治疗环枕区及颈段椎管哑铃形肿瘤的一种较理想方法，具有术野开阔、肿瘤显露充分、全切率高等优点。

Surgical treatment in the dumbbell tumors of the craniocervical junction and cervical spinal canal

Objective To explore approaches to remove dumbbell tumors of the craniocervical junction and cervical spinal canal. Methods The modified far lateral suboccipital approach and the post-middle approach were used in 26 patients with dumbbell tumors of the craniocervical junction and cervical spinal canal ,the clinical data were analyzed retrospectively. Results There were total removal tumor in 23 cases at one-stage operation, and subtotal removal in 3 cases. There was no operative mortality. No complications occurred due to the operation. Postoperative follow-up ranged from 1 to 9 years, all patients got good recovery, except one subtotal resected chordoblastoma relapsed in two years. Conclusion The modified far lateral suboccipital approach and the post-middle approach are effective to remove the dumbbe.ll tumors of the craniocervical junction and cervical spinal canal, which are characterized by wide operation field, good tumor exposure, and high total removal ratio.
