摘　　要：目的:对比脊髓型颈椎病患者术前、术后椎旁肌MRI表现的变化,探讨椎旁肌面积变化与术后轴性症状的相关性。方法:收集确诊的脊髓型颈椎病并行颈后路单开门椎管成形术患者30例,测量术侧椎旁肌的净面积。结果:椎旁肌净面积除C_(3~4)、C_(4~5)节段呈先增后减的趋势,其余节段呈逐步递减的趋势。结论:C_(3~4)、C_(4~5)节段椎旁肌净面积在术后3~6个月内有一急性或亚急性的增大过程,可能与轴性症状的发生存在相关性;而从中期随访看,颈后椎旁肌是一个逐渐萎缩、脂肪化的过程,推测脂肪化与轴性症状的发生无相关性。Objective:To compare the changes of MRI features of the paravertebral muscle in patients with cervical spondylosis before and after posterior cervical canal plasty,and explore the correlation between the changes of the paravertebral muscle area and postoperative axial symptoms.Methods:Thirty patients with cervical spondylosis who underwent posterior cervical canal plasty were enrolled,and the net area of the paravertebral muscle in operative side was measured.Results:The net area of the paravertebral muscle increased first and then decreased in the C_(3~4) and C_(4~5) segments and decreased gradually in other segments.Conclusions:The net area of the paravertebral muscle in the C_(3~4) and C_(4~5) segments has an acute or subacute increase within 3~6 months after surgery,which may be related to the occurrence of axial symptoms.However,from the mid-term follow-up results,the posterior cervical paravertebral muscle exhibits gradual atrophy and steatosis,and it is speculated that there is no correlation between steatosis and axial symptoms.
