Abstract

Background:  To evaluate the diagnostic efficacy of High-Resolution Ultrasonography as compared to Magnetic Resonance Imaging for the evaluation of symptomatic & non-symptomatic Temporomandibular Joint in open and closed mouth positions. Materials & Method: This is a prospective study 6 individual (12 joints) with click, crepitation & pain in 9 joints & a control group of 2 normal joints of one individual were concluded in this study.  One among the 6 patients with a symptom-free joint was included in this study as a control. Results: In the present study, 7 joints diagnosed an anterior disc displacement with reduction 28.5% revealed displaced disc & 28.5% mildly interiorly displaced disc 42.8% were not visible in the closed position. In open mouth view, all the reduced discs were visible. Conclusion: The results of the current study imply that it is difficult to detect the actual disc position and a clear anatomical relation and structure of the disc in high-resolution ultrasonography in closed mouth view in disc disorders but open in mouth view It looks promising to detect the disc position. It's difficult to diagnose arthritic changes of TMJ in ultrasonography. However, further studies, including more patients, should be carried out to support and make available the widespread use of ultrasonography in the diagnosis of temporomandibular disorders and classification may be helpful for future studies.
