摘要
目的:分析比较自然病程中青少年颞下颌关节不可复性前移位的影像学转归。方法 :选择2010年1月—2013年6月于我院关节专科随访的单侧颞下颌关节盘不可复性前移位的124例青少年患者。通过MRI检查评价健、患侧髁突骨质退变、关节盘变形和积液的发生率,比较其病程进展。采用SAS 9.13软件包对数据进行统计学分析。结果:初诊时,患侧髁突骨质退变和积液的检出率显著高于健侧(P<0.05)。对随访前、后进行比较,发现患侧关节盘变形的检出率显著升高(P<0.05),而患侧积液的检出率显著降低(P<0.05),患侧髁突骨质退变率由60.48%上升为69.36%,但无显著差异(P=0.14)。结论:青少年颞下颌关节盘不可复性前移位与髁突骨质退变和关节腔积液显著相关。随着病程延续,其关节盘变形发生率显著升高,关节液显著减少。
PURPOSE： To assess radiographic progression in adolescents with anterior disc displacement without reduction （ADDWoR） without treatment using serial MRI. METHODS： A retrospective review was conducted in patients under 20 years of age with unilateral ADDWoR who underwent MRI examination twice over 6 months without any intervention between January 2010 and June 2013, On MRI, bone changes ,disc deformation and effusion were evaluated. SAS 9.13 software package was used for statistical analysis. RESULTS： One hundred and twenty-two patients （101 females, 23 males） with a mean age of 16.4 years underwent MRI examination twice at least 6 months apart （mean： 13.6 months）. At initial visit, there was significant difference between the involved and the non-involved side in condylar degeneration and effusion. Following no intervention, the frequency of effusion significantly decreased, the frequency of disc deformation significantly increased, and the frequency of condylar degeneration increased from 60.48% to 69.36% without significant difference. CONCLUSIONS： During the period of clinical observation, there was significant decrease in effusion and significant increase in disc deformation. Whilst there was an increase in condylar surface change, but without significant difference.
