To determine the association between unilateral temporomandibular joint disorder (TMD) and the presence of imaging abnormalities in the contralateral, asymptomatic joint.
MRI studies of 219 subjects with symptoms of unilateral TMD were examined for signs of disc displacement, osteoarthritis, disc deformation, and effusion in both temporomandibular joints (TMJ). The Chi-Square test and stepwise logistic regression analysis were performed.
Disc displacement, osteoarthritis, disc deformation, and effusion were more common on the symptomatic side. However, in the category of disc displacement with a reduction in open mouth position (DDWR), the difference was not significant between the symptomatic and the asymptomatic TMJs. Stepwise logistic regression showed that the presence of any imaging abnormality other than DDWR was related to osteoarthritis and disc deformity on the symptomatic side. On the other hand, the presence of any MRI abnormality (including DDWR) on the asymptomatic side was related only to the presence of osteoarthritis on the symptomatic side.
Unilateral symptomatic TMD is related to the presence of imaging abnormalities on the contralateral, asymptomatic side, suggesting that the development and progression of joint changes in symptomatic and contralateral asymptomatic TMJs are interrelated.
确定单侧颞下颌关节紊乱（TMD）与对侧无症状关节影像学异常之间的关系。
对 219 例单侧 TMD 症状患者的 MRI 研究进行检查，以观察双侧颞下颌关节（TMJ）的盘移位、骨关节炎、盘变形和关节积液等征象。采用卡方检验和逐步逻辑回归分析。
在有症状的一侧，盘移位、骨关节炎、盘变形和关节积液更为常见。然而，在开口位减小的盘移位（DDWR）分类中，有症状和无症状 TMJ 之间的差异无统计学意义。逐步逻辑回归显示，除 DDWR 以外的任何影像学异常的存在与有症状侧的骨关节炎和盘变形有关。另一方面，无症状侧存在任何 MRI 异常（包括 DDWR）仅与有症状侧的骨关节炎存在有关。
单侧有症状的 TMD 与对侧无症状关节影像学异常的存在有关，这表明有症状和对侧无症状 TMJ 中关节变化的发生和进展相互关联。
