The aim of the study was to evaluate the extent of agreement between the findings of ultrasonography (US) and magnetic resonance imaging (MRI) in the assessment of anterior disc displacement (ADD), with or without reduction, and to assess the sensitivity, specificity and the accuracy of the US examination in establishing diagnosis. Fifty-two temporomandibular joints (TMJ) in 52 patients with chronic TMJ pain were examined by US and MRI with respect to ADD, with, and without reduction of the TMJ. The level of agreement between US and MRI findings was evaluated. The sensitivity, specificity, and the accuracy of US were found to be respectively 91%, 16% and 82% in the assessment of ADD; 70%, 38% and 57% in ADD with reduction; 50%, 89% and 76% in ADD without reduction. The findings of both methods were in agreement with each other. US method is fairly sensitive especially in detecting ADD, and it is very reliable in determining the absence of ADD without reduction. However, it was not found to be as quite effective in demonstrating ADD whether it was with or without reduction.
本研究旨在评估超声（US）与磁共振成像（MRI）在评估伴或不伴复位的前盘移位（ADD）方面的一致性程度，并评估 US 检查在建立诊断中的敏感性、特异性和准确性。对 52 例慢性颞下颌关节痛患者的 52 个 TMJ 进行 US 和 MRI 检查，评估 TMJ 的 ADD，以及是否伴有 TMJ 的复位。评估了 US 和 MRI 检查结果之间的一致性程度。在评估 ADD 时，US 的敏感性、特异性和准确性分别为 91%、16%和 82%；在伴有复位的 ADD 中，分别为 70%、38%和 57%；在不伴有复位的 ADD 中，分别为 50%、89%和 76%。两种方法的检查结果相互一致。US 方法特别敏感，特别是在检测 ADD 方面，而且在确定不伴有复位的 ADD 方面非常可靠。然而，对于伴有或不伴有复位的 ADD，其显示效果并不十分有效。
