This study investigated the temporomandibular joint (TMJ) morphological changes in women with fibromyalgia (FM) through clinical and tomographic evaluation.: Ten women diagnosed with myofascial pain who were being treated for FM in a university hospital were included in this study. The data were collected through clinical examination and cone beam computed tomography evaluation of the TMJ in closed and open mouth positions.: All patients had crackling in the joint, a habit of grinding teeth during sleep, muscle stiffness, and tinnitus. The tomographic findings revealed a higher frequency of condylar bone wear, reduction of joint space, and posterior positioning of the mandibular condyle. The temporomandibular disorders with the highest prevalence were osteoarthritis and disc displacement with reduction.: The findings suggest that women with FM have a high frequency of TMD related to the displacement of the articular disc, condyle position, and occurrence of osteoarthritis.
本研究通过临床和影像学评估探讨了纤维肌痛（FM）女性颞下颌关节（TMJ）的形态变化。
该研究纳入了 10 名在大学医院接受 FM 治疗的肌筋膜疼痛诊断患者。通过对 TMJ 在闭口和开口位置的临床检查和锥形束计算机断层扫描（CBCT）评估收集数据。
所有患者的关节均有弹响声、睡眠磨牙习惯、肌肉僵硬和耳鸣。影像学检查发现髁状突骨磨损、关节间隙减小和下颌髁后移位的发生率更高。最常见的颞下颌关节紊乱是骨关节炎和伴髁突位置改变的关节盘移位。
研究结果表明，FM 女性的 TMJ 疾病与关节盘移位、髁突位置和骨关节炎的发生有关。
