摘要：

目的通过诊断性试验的方法，评价高分辨率超声在颞下颌关节不可复性盘前移位诊断中的价值。方法纳入35例临床初步诊断为颞下颌关节不可复性盘前移位患者的40侧颞下颌关节，所有关节均进行了高分辨率超声检查及MRI检查。以MRI检查结果作为金标准，计算高分辨率超声检查的敏感度、特异度、准确度、阳性预测值、阴性预测值、阳性似然比、阴性似然比。结果40侧颞下颌关节中，MRI确诊为不可复性盘前移位者23侧，非不可复性盘前移位者17侧。高分辨率超声诊断颞下颌关节不可复性盘前移位的敏感度、特异度、准确度、阳性预测值、阴性预测值、阳性似然比、阴性似然比分别为82.6%、94.1%、92.5%、0.95、0.80、14.04、0.19。结论高分辨率超声在颞下颌关节不可复性盘前移位中具有较高的诊断价值。

Abstract:

Objective To assess the diagnostic value of high-resolution ultrasonography for detecting of anterior disc displacement without reduction（ADDWR） of temporomandibular joint（TMJ）. Methods Thirty-five participants with 40 TMJs which were initially diagnosed as ADDWR were included. All the participants got both high-resolution ultrasonography and MRI examination. The results of MRI in diagnosis of ADDWR were considered as gold standard. Sensitivity, specificity, accuracy, positive predict value, negative predict value, positive likelihood ratio and negative likelihood ratio were calculated. Results In 40 TMJs, MRI revealed that there were 23 TMJs with ADDWR, and 17 disease-free. The sensitivity, specificity, accuracy, positive predict value, negative predict value, positive likelihood ratio and negative likelihood ratio of high-resolution ultrasonography were 82.6%, 94.1%, 92.5%, 0.95, 0.80, 14.04, 0.19, respectively. Conclusion The high -resolution ultrasonography has a relatively high diagnostic value in detecting ADDWR of TMJ.
