高分辨率超声诊断颞下颌关节盘前移位的初步临床研究

A preliminary research on application of high-resolution ultrasonography on the diagnosis of temporomandibular joint disorder with anterior disc displacement

目的探讨高分辨率超声(HR-US)诊断颞下颌关节紊乱病(TMD)关节盘前移位(ADD)的可行性。方法对40例TMD患者的40侧关节作HR-US(静态图像和动态图像)与关节造影检查。结果HR-US在显示可复性盘前移位与关节造影显示中等一致性,在显示不可复性盘前移位与关节造影显示高度一致性。结论HR-US在诊断ADD方面显示较强的可行性,可以作为ADD诊断方法在临床上应用。

Objective To diagnosis the anterior disc displacement of temporomandibular joint disorders （TMD） with the use of high-resolution uhrasonography （HR-US）, and to evaluate its feasibility in clinical application. Methods 40 TMD patients were choosen to be examined by HR-US and arthrography. Results HR-US is consistent with arthrography in some extent in the diagnosis of anterior disc displacement; HR-US is highly consistent with arthrography in the diagnosis of anterior disc displacement without reduction. Conclusions It is suggested that HR-US is feasible in the diagnosis of anterior disc displacement of TMD and can be used as a new clinical diagnosis method.
