　　目的分析颈后路单开门椎管扩大成形术治疗颈椎管狭窄症的疗效。方法对我院2006年1月至2011年1月行后路单开门椎管扩大成形术治疗的32例颈椎管狭窄患者进行随访，平均随访2.4年。从手术时间、出血量、并发症的数量和类型以及手术前和手术后的JOA评分方面分析手术疗效。结果所有患者的JOA评分较术前均有不同程度的提高，JOA平均改善率：（55.8±22.3）%。平均手术出血量205 mL，手术时间75 min，轴性症状1例、椎板骨折1例、硬膜外血肿1例。结论颈椎后路单开门椎管扩大成形术操作相对安全、简单、治疗颈椎管狭窄症疗效确切。

Objective To observe the results of posterior unilateral open-door laminoplasty for cervical spinal stenosis disease. Methods From January 2006 to January 2011, 32 cases with cervical spinal stenosis disease were treated by unilateral open-door laminoplasty followed-up for 1 years to 6 years. Bleeding volume, operation time , the numbers and types of complications , and preoperative along with postoperative JOA scores were analyzed. Results Postoperative JOA scores of all patients have been improved after operation. The JOA average improvement rate is (55.8±22.3)%. Bleeding volume is 205 mL, operation time is 75 min, postoperative axial sympotms 1 case, lamina fracture 1 case, epidural hematoma 1 case, respectively. Conclusion Posterior unilateral open-door laminoplasty is relative safety, simple, effective, the treatment for cervical spinal stenosis disease is definite.
