In this study, we investigated joint effusion in patients with temporomandibular disorders (TMDs) with disc displacement. The magnetic resonance (MR) images of 97 temporomandibular joints (TMJs) were evaluated, and the appearance of joint effusion was investigated. Myofascial pain and TMJ pain were considered in addition to the duration from manifestation. Disc displacement with and without reduction, as well as the region and the area of joint effusion, were investigated using the MR images. Fisher's test was used for the analyses. Joint effusion was recognized in 70 TMJs, including 55 in the superior articular cavity, 1 in the inferior articular cavity, and 14 in both the superior and inferior articular cavities. The appearance of joint effusion did not differ with the existence of myofascial pain or TMJ pain. The region of joint effusion did not differ between disc displacement with and without reduction. A larger area of joint effusion was recognized in disc displacement without reduction ( < 0.05). The results showed that the amount of synovial fluid in the joint effusion did not change with the existence of myofascial pain or TMJ pain. Joint effusion commonly appeared in disc displacement without reduction.
在本研究中，我们调查了伴盘移位的颞下颌关节紊乱病（TMDs）患者的关节积液情况。对97个颞下颌关节（TMJ）的磁共振（MR）图像进行了评估，并研究了关节积液的表现。除了从发病开始的持续时间外，还考虑了肌筋膜疼痛和TMJ疼痛。利用MR图像研究了伴与不伴复位的盘移位情况，以及关节积液的区域和面积。采用Fisher检验进行分析。在70个TMJ中发现有关节积液，其中55个位于上关节腔，1个位于下关节腔，14个上下关节腔均有积液。关节积液的表现与肌筋膜疼痛或TMJ疼痛的存在与否无关。伴与不伴复位的盘移位之间，关节积液的区域没有差异。在不伴复位的盘移位中，关节积液面积更大（<0.05）。结果表明，关节积液中的滑液量不会因肌筋膜疼痛或TMJ疼痛的存在而改变。关节积液常见于不伴复位的盘移位。
