    摘  要：［目的］探讨脊柱侧弯并发Chiari畸形的诊断和治疗方法。［方法］本组12例脊柱侧弯并发Chiari畸形的患者，其中有7例同时伴有脊髓空洞症，所有患者均先由神经外科行枕大孔扩大成形术或空洞分流术，二期行脊柱侧弯后路矫形术。［结果］Cobbs角术前平均71°，术后平均24°，矫正率为66%。脊柱矫形术后随访1~4 a，平均24 a，没有发生脱钩、断钉及假关节现象；没有出现新的神经损害表现；感觉障碍及腹壁浅反射减弱的症状没有加重。［结论］对于脊柱侧弯并发Chiari畸形、脊髓空洞症的患者，术前应完善检查、明确诊断；先进行枕大孔扩大成形术或空洞分流术，二期行脊柱侧弯后路矫形术，可以减少脊柱侧弯矫形时引起的神经损害并发症。
