INTRODUCTION
This study was conducted to determine the effectiveness of ultrasonographic imaging for diagnosing temporomandibular joint internal derangements.
MATERIALS AND METHODS
Ultrasonographic and magnetic resonance imaging scans of temporomandibular joints were obtained bilaterally in 55 patients who had temporomandibular joint disorders and who were diagnosed with temporomandibular joint internal derangements following a clinical examination. Diagnostic accuracy of ultrasonographic imaging was assessed considering magnetic resonance imaging as the gold standard method.
RESULTS
When the results of ultrasonographic imaging and magnetic resonance imaging were compared, the diagnostic accuracy of ultrasonographic imaging was 0.81 for detecting TMJ disc displacement. The diagnostic accuracy of ultrasonographic imaging in detecting TMJ disc position was 0.81 in the closed-mouth position and 0.93 in the open-mouth position.
CONCLUSION
As a noninvasive and reproducible imaging method acquiring dynamic images, ultrasonographic imaging is a successful method in the evaluation of temporomandibular joint disc displacement.
简介
本研究旨在确定超声成像在诊断颞下颌关节内部紊乱方面的有效性。
材料和方法
对 55 例颞下颌关节紊乱患者进行双侧颞下颌关节超声和磁共振成像扫描，这些患者在临床检查后被诊断为颞下颌关节内部紊乱。以磁共振成像为金标准方法，评估超声成像的诊断准确性。
结果
当比较超声成像和磁共振成像的结果时，超声成像检测 TMJ 盘移位的诊断准确性为 0.81。超声成像在闭口位和张口位检测 TMJ 盘位置的诊断准确性分别为 0.81 和 0.93。
结论
作为一种获取动态图像的非侵入性且可重复的成像方法，超声成像在评估颞下颌关节盘移位方面是一种成功的方法。
