The purpose of the study was to test the hypothesis that condylar shape varies based upon the condition of anterior disk displacement in young adolescent patients with temporomandibular disorder (TMD). The study design consisted of 96 juvenile female patients (aged 9 to 20; 15.1 +/- 2.3 yrs.) with clinical signs and/or symptoms of TMD. Bilateral high-resolution magnetic resonance imaging scans were performed in frontal and horizontal views with the mandible in the closed position. Disk positions were evaluated to classify the patients into three diagnostic groups. The results of the study, using ANOVA and Bonferroni tests, demonstrated significant differences among the groups. The conclusion drawn from the study was that condylar shape and size vary based on anterior disk position in juvenile females with TMD. The study's results suggest that disk displacement results in a smaller condyle.
在患有颞下颌关节紊乱病（TMD）的青少年患者中，髁突形状会因前盘移位情况而有所不同。该研究设计纳入了96名患有TMD临床体征和/或症状的青少年女性患者（年龄9至20岁；平均年龄15.1±2.3岁）。在下颌处于闭合位置时，从正面和水平位进行了双侧高分辨率磁共振成像扫描。评估盘状位置以将患者分为三个诊断组。使用方差分析和邦费罗尼检验的研究结果表明，各组之间存在显著差异。该研究得出的结论是，在患有TMD的青少年女性中，髁突形状和大小会因前盘位置而有所不同。该研究结果表明，盘状移位会导致髁突变小。
