目的：观察“单开门”椎管扩大成形术治疗各种颈椎管狭窄症患者的术后功能改善情况。方法：对21例颈椎管狭窄症患者采用“单开门”椎管扩大成形术治疗，随访时间3个月～4年5个月。结果： 脊髓型颈椎病致椎管退变性狭窄（CSM）组 11例，发育性椎管狭窄症（DCS） 8例及后纵韧带骨化症（OPLL ）2例，术后2周及三月门诊随访时评分，三组病例评分均明显提高，患者的症状及体征也获得了明显的改善，未见“再关门”及脊柱不稳现象。结论：“单开门”椎管扩大成形术治疗各种原因所致的颈椎管狭窄症减压效果确实，并发症少，出血少，对颈椎的稳定性无影响。

Objective: To observe the results of expansive open-door laminoplasty of cervical spine for cervical spinal stenotic myelopathy. Methods: From March 1995 to March 2000, 21 cases were treated by expansive open-door laminoplasty of cervical spine and had been followed up for 3 months to 4 years and 5 months. Results: Good results were obtained at 2 weeks and 3 months after operation among the CSM（11 cases）, DCS（8 cases）and OPLL(2 cases). The symptoms and signs were improved, and instability of the cervical spine and reclosed open-door were not found. Conclusion: The results of expansive open-door laminoplasty of cervical spine for cervical spinal stenotic myelopathy were good and stable, there were fewer complications and less hemorrhage, and it did not affect the stability of cervical spine.
