The study goal was to define the positive predictive value (PPV) for the diagnosis of disc displacement of the temporomandibular joint (TMJ) with the use of high-resolution ultrasonography (HR-US).
The HR-US reports for 29 patients aged 19 to 62 years who had a prospective clinical diagnosis of TMJ internal derangement were correlated with magnetic resonance results.
For the prospective HR-US interpretation, the PPV for disc displacement was 97% at the closed-mouth position and 88% at the maximum-mouth opening position.
The PPV for the HR-US diagnosis of disc displacement is high.
本研究的目标是确定使用高分辨率超声（HR-US）诊断颞下颌关节（TMJ）盘移位的阳性预测值（PPV）。
对29例年龄在19至62岁之间、临床前瞻性诊断为TMJ内部紊乱的患者的HR-US报告与磁共振成像结果进行相关性分析。
对于前瞻性HR-US解读，闭口位时盘移位的PPV为97%，最大开口位时为88%。
HR-US诊断盘移位的PPV较高。
