了解下颌骨不对称的发生机制，对于指导临床治疗和了解咀嚼功能障碍的发生发展过程具有重要意义。为了研究形态和功能对MA的影响，我们评估了关节盂窝的三维位置及其与不对称髁突平移运动的关系。在这项回顾性研究中，根据门顿偏离正中矢状面至少4 mm，将50例既往接受过计算机断层扫描的受试者分为MA组和对照组。使用三维分析程序评估关节盂窝位置。用计算机轴向成像仪记录并测量髁突的平移运动。测量每个参数的侧对侧不对称性。计算不对称指数值，评价关节窝位置与髁突运动的相关性。采用Wilcoxon符号秩检验、Mann-Whitney U检验和斯皮尔曼秩相关进行统计分析。在MA组中，移位侧的关节盂窝位置与非移位侧和对照组相比明显位于下方和后方。髁突路径长度和髁突矢状面倾斜度在移位侧显著大于非移位侧，而髁突横面倾斜度无显著差异。关节窝前后位置不对称指数与髁突路径长度和双侧髁突横倾角显著相关。在对照组中，形态和功能参数之间没有显著相关性。这项研究没有考虑可能影响髁突运动的肌肉活动和椎间盘位置。MA患者髁突平移运动的功能不对称性与关节窝位置的不对称性密切相关。
Understanding the mechanism of mandibular asymmetry (MA) is important to provide suggestions for occlusal treatment and to know the developmental process of masticatory dysfunction. To investigate the morphological and functional effects on MA, we evaluated the three-dimensional position of the glenoid fossa and its relationship to asymmetrical condylar translational movement. In this retrospective study, 50 subjects who previously underwent computed tomography for surgical purposes were divided into MA and control groups according to a menton deviation of at least 4 mm from the mid-sagittal plane. The glenoid fossae positions were evaluated using a three-dimensional analysis program. Condylar translational movements were recorded and measured by computerized axiography on protrusion. Side-to-side asymmetry was measured for each parameter. Asymmetry index value was calculated to assess the correlation between glenoid fossa position and condylar movement. Wilcoxon’s signed-ranked test, Mann–Whitney U-test, and Spearman’s rank correlation were used for the statistical analysis. In the MA group, glenoid fossa position on the shifted side was significantly inferior and posterior as compared to that on the non-shifted side and of the control group. Condylar path length and sagittal condylar inclination were significantly greater on the shifted side versus non-shifted side, while no significant difference was found in transverse condylar inclination. The asymmetry index of the anterior–posterior glenoid fossa position was significantly correlated with that of condylar path length and bilateral transverse condylar inclination. In the control group, there were no significant correlations among the morphological and functional parameters. This study did not consider muscle activity and disc position, which may affect condylar movement. Functional asymmetry of condylar translational movements is closely related to asymmetry of glenoid fossa position in MA patients.
