目的 探讨经远外侧枕下入路切除高颈段椎管内外哑铃型肿瘤及下斜坡肿瘤的治疗效果及手术技巧。方法 对 14例高颈段椎管内外哑铃型肿瘤及下斜坡肿瘤 ,采用外侧枕下入路进行手术切除。结果 肿瘤全切除 10例 ,次全切除 4例。所有患者术后恢复良好 ,未出现与手术入路有关的严重并发症。结论 远外侧枕下入路具有手术径路短、视野宽广、显露硬膜内外病变清楚等优点 ,可减少不必要的手术步骤 ,是治疗高颈段椎管内外哑铃型肿瘤及下斜坡肿瘤的一种有效手术方法。
Objective To investigate the therapeutic effect and surgical technique of resection of dumbbell tumors in the upper and lower cervical vertebra and the tumor of the lower slopes by distal lateral suboccipital approach. Methods 14 cases of high cervical internal and external spinal canal dumbbell tumor and lower slope tumor, lateral suboccipital approach for surgical resection. Results Tumor resection in 10 cases, subtotal resection in 4 cases. All patients recovered well and did not experience serious complications associated with surgical approach. Conclusion The far-lateral suboccipital approach has the advantages of short operative path, wide field of vision, clear and clear lesions inside and outside the dura mater, which can reduce unnecessary surgical steps and is a kind of treatment for dumbbell tumors in the upper and lower cervical spinal canal and tumors of the lower slopes Effective surgical methods.
