The significance of the position of the mandibular condyle in the glenoid fossa remains a controversial subject.
This study evaluated the relationship between condyle position and disk displacement.
Fifty-two asymptomatic volunteers and 130 symptomatic patients underwent linear tomography and bilateral temporomandibular joint magnetic resonance scans.
There was a higher prevalence of distal condyles in symptomatic patients with disk displacement compared with asymptomatic volunteers (P <.05). Distally positioned condyles identified joints with disk displacement with reduction, disk displacement without reduction, or a symptomatic normal joint with a sensitivity of 0.64, 0.56, and 0.33, respectively. Distally positioned condyles identified joints with disk displacement with reduction, disk displacement without reduction, or a symptomatic normal joint with a specificity of 0.56, 0.65, and 0.55, respectively.
There were more distal condyles in symptomatic subjects with disk displacement, but the reliability of a distal condyle to predict the presence or absence of disk displacement was low.
下颌髁突在关节窝中的位置的意义仍然是一个有争议的话题。
本研究评估髁突位置与盘移位之间的关系。
52名无症状志愿者和130名有症状患者接受了线性断层扫描和双侧颞下颌关节磁共振扫描。
与无症状志愿者相比，有盘移位的有症状患者中髁突远端位置的患病率更高（P<.05）。远端定位的髁突分别以0.64、0.56和0.33的敏感性识别出有可复性盘移位、不可复性盘移位或有症状的正常关节。远端定位的髁突分别以0.56、0.65和0.55的特异性识别出有可复性盘移位、不可复性盘移位或有症状的正常关节。
有盘移位的有症状受试者中髁突远端位置更多，但远端髁突预测盘移位存在与否的可靠性较低。
