摘要
目的:探讨伴有颞下颌关节紊乱综合征(temporomandibular disorders,TMD)的错畸形患者的髁突位置及对称性。方法:在就诊的错畸形患者中,选取有TMD症状的15例患者纳入实验组,并选取15例无症状患者作为对照组。分别对实验组和对照组行双侧颞下颌关节CT扫描,选取适当的断层并测量其关节间隙及对称性。采用SPSS17.0软件包对数据进行统计学处理。结果:实验组患者的髁突位置明显偏后位,而对照组患者的髁突位置稍前位。实验组患者患侧髁突水平倾斜角较健侧大(P<0.05),而垂直倾斜角较健侧小(P<0.05),两侧髁突内外径、前后径、髁突长轴、髁突中心至正中矢状面距离、两侧髁突前后距均无显著差异。结论:颞下颌关节紊乱综合征患者的髁突位置明显偏后位,且两侧髁突存在垂直向不对称。
PURPOSE： To investigate condylar position and condylar symmetry in patients with temporomandibular disorders （TMD） as well as malocclusion. METHODS： Fifteen patients with TMD and malocclusion were selected for the experiment, 15 asymptomatic patients served as controls. The bilateral temporomandibular joints of all subjects were evaluated by computed tomography （CT） imaging. Both the joint spaces and the condylar symmetry were determined, based on the axial CT images properly chose. All statistical analysis were performed using SPSS17.0 software package. RESULTS： The condyle of the patients in the experimental group were seated more posteriorly, while slight anterior condylar position were found in the control group. In the experimental group, the horizontal angle of the condyle in the symptomatic side was larger than that in the asymptomatic side （P〈0.05）, while the vertical angle was just opposite （P〈 0.05）. No statistically significant asymmetries were found in the mediolateral diameter,the anteroposterior diameter, the angle of condylar axis, the distance between condylar center to midsagittal plane and anteroposterior difference of condyle center. CONCLUSION： Obvious posterior condylar position and vertical asymmetry exist in patients with temporomandibular disorders.
