BACKGROUND
This study was to evaluate the diagnostic significance of Magnetic Resonance Imaging (MRI) in distinguishing temporomandibular disorders (TMD).
METHODS
A total of 684 patients with TMD were included in the study. Diagnosis for TMD was conducted according to the international criteria. Two professional radiologists were selected for professional training, and the Kappa values were compared for the diagnosis results to determine the consistency of the diagnosis. Then MRI images of these 684 patients were analyzed and the diagnosis results were obtained.
RESULTS
MRI can be used for the diagnosis of TMD. There were significantly more females (518 cases) than males (166 cases) with TMD; Disc displacement with/without reduction is more common in the youth group, with the majority aged 20-30 years. The highest incidence of temporomandibular joint osteoarthrosis is in the 60-year-old age group, followed by the 70-year-old age group.
CONCLUSIONS
Bilateral temporomandibular joint MRI can clearly show their changes; there are significantly more female with TMD than male; osteoarthritis has a significant correlation with age.
背景
本研究旨在评估磁共振成像（MRI）在鉴别颞下颌关节紊乱（TMD）方面的诊断意义。
方法
共纳入 684 例 TMD 患者。根据国际标准进行 TMD 诊断。选择 2 名专业放射科医生进行专业培训，并比较诊断结果的 Kappa 值，以确定诊断的一致性。然后分析这 684 例患者的 MRI 图像，并获得诊断结果。
结果
MRI 可用于 TMD 的诊断。TMD 患者中女性（518 例）明显多于男性（166 例）；伴/不伴复位的盘移位在青年人群中更为常见，多数年龄在 20-30 岁。颞下颌关节骨关节炎的发病率最高在 60 岁年龄组，其次是 70 岁年龄组。
结论
双侧颞下颌关节 MRI 可清晰显示其变化；TMD 患者中女性明显多于男性；骨关节炎与年龄有显著相关性。
