Temporomandibular joint disorders (TMD) commonly cause restricted mouth opening and pain, significantly affecting patients' quality of life. This study aims to explore the relationship between common clinical symptoms-clicking and limited mouth opening-and MRI findings in patients diagnosed with TMD.
A total of 46 patients, with either clicking sounds or limited mouth opening, were examined using a 3T MRI scanner. The study evaluated disc position, disc deformity, and signs of osteoarthrosis, comparing MRI findings with clinical symptoms.
Results revealed that disc deformation was positively correlated with clicking. In contrast, limited mouth opening was significantly associated with anterior disc displacement without reduction and osteoarthrosis, indicating joint degeneration.
The findings highlight that limited mouth opening is a more reliable clinical indicator of TMD than joint clicking, which may not always reflect underlying disc displacement. Although clicking was observed in discs with and without displacement, limited mouth opening showed a strong correlation with degenerative changes in the temporomandibular joint. The study underscores the reliability of clinical symptoms of TMD, which play a crucial role in treatment planing.

颞下颌关节紊乱病（TMD）常导致张口受限和疼痛，严重影响患者的生活质量。本研究旨在探讨已确诊TMD患者的常见临床症状——弹响和张口受限——与MRI表现之间的关系。
共有46例有弹响或张口受限症状的患者接受了3T MRI扫描仪检查。该研究评估了关节盘位置、关节盘变形以及骨关节炎体征，并将MRI表现与临床症状进行了比较。
结果显示，关节盘变形与弹响呈正相关。相比之下，张口受限与不可复性关节盘前移位及骨关节炎显著相关，提示关节退变。
研究结果表明，与关节弹响相比，张口受限是TMD更可靠的临床指标，弹响可能并不总能反映潜在的关节盘移位。尽管在有移位和无移位的关节盘中均观察到弹响，但张口受限与颞下颌关节的退行性改变密切相关。该研究强调了TMD临床症状的可靠性，其在治疗方案制定中起着关键作用。
