INTRODUCTION
Temporomandibular joint (TMJ) dysfunction is a common condition that is best evaluated with magnetic resonance (MR) imaging. The aim of this study was to investigate the characteristics of the patients with TMJ osteoarthrosis on MR imaging.
METHODS
The MR images of 206 TMJs of 103 patients with temporomandibular disorders (TMD) were evaluated retrospectively in this study. The relationship between osteoarthrosis and age, gender, TMJ pain and MR imaging findings, such as disc displacement with or without reduction and TMJ effusion, was analysed.
RESULTS
The patients with TMJ osteoarthrosis (mean: 51.6 years) were significantly older than those without osteoarthrosis (mean: 44.8 years, P = 0.027). The incidence of the patients with TMJ osteoarthrosis was significantly different between with (10.0 %) and without reduction (57.0 %, P < 0.001). Logistic multivariate regression analysis demonstrated that disc displacement without reduction was significant in patients with TMJ osteoarthrosis (odds ratio = 12.285, P < 0.001).
CONCLUSIONS
This study suggests that characteristics of the patients with TMJ osteoarthrosis on MR imaging include older and disc displacement without reduction.
简介
颞下颌关节（TMJ）功能障碍是一种常见病症，最好通过磁共振成像（MR）进行评估。本研究旨在探讨 TMJ 骨关节炎患者的 MR 影像学特征。
方法
本研究回顾性分析了 103 例颞下颌关节紊乱（TMD）患者的 206 个 TMJ 的 MR 图像。分析了骨关节炎与年龄、性别、TMJ 疼痛以及 MR 成像表现（如伴或不伴复位的盘移位和 TMJ 积液）之间的关系。
结果
TMJ 骨关节炎患者（平均年龄：51.6 岁）明显比无骨关节炎患者（平均年龄：44.8 岁，P=0.027）年龄更大。伴或不伴复位的 TMJ 骨关节炎患者的发生率有显著差异（P<0.001）。多变量逻辑回归分析表明，伴 TMJ 骨关节炎的患者中，无复位的盘移位是显著的（比值比=12.285，P<0.001）。
结论
本研究表明，TMJ 骨关节炎患者的 MR 影像学特征包括年龄较大和无复位的盘移位。
