“…Another study conducted by Emshoff et al, showed more precise outcomes on use of dynamic US instead of static US [34].Cut-off value was 2 mm in this study, whereas according to Tognini et al, joint effusion was seen when the distance between the lateral pole of condyle and lateral part of the articular capsule was greater than 3mm [35].…”

“…There is definitely scope for US for assessment of masseter muscle in real-time. This has been documented widely in the literature with masseter muscle thickness demonstrating differences in posterior crossbite cases and their relationship to TMDs 5,54,111,112 . But there is concern that some findings can be controversial and others produce non-conclusive results.…”

“…It is a noninvasive, dynamic, inexpensive imaging technique which can be useful in diagnosing articular disc displacements. Variable levels of sensitivity were reported in detection of disc displacement, therefore further studies are required [2][3][4][5][20][21][22][23][24]. It is a technique that depends widely on the operator.…”

Aims: The purpose of this study was to determine the diagnostic value of high-resolution ultrasonography (US) in temporomandibular joint (TMJ) disc displacements.Materials and methods: A number of 74 patients (148 TMJs) with signs and symptoms of TMJ disorders, according to the Research Diagnostic Criteria for Temporomandibular Disorders, were included in this study. All patients received US and magnetic resonance imaging (MRI) of both TMJs 1 to 5 days after the clinical examination. MRI examinations were performed using 1.5 T MRI equipment (Siemens Avanto, Siemens, Erlangen). Ultrasonographic examination was performed on a Hitachi EUB 8500 (Hitachi Medical Corp., Tokyo, Japan) scanner with L 54 M6.5-13 MHz linear transducer.Results: MRI depicted 68 (45.95%) normal joints, 47 (31.76%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction and 34 (22.97%) with degenerative changes. US detected 78 (52.7%) normal joints, 37 (25%) with disc displacement with reduction, 33 (22.3%) with disc displacement without reduction and 21 (14.19%) with degenerative changes. Compared to MRI, US showed a sensitivity of 93.1%, specificity of 87.88%, accuracy of 90.32%, a positive predictive value of 87.1% and a negative predictive value of 93.55% for overall diagnosis of disc displacement. The Youden index was 0.81.Conclusions: Based on our results, high-resolution ultrasonography showed high sensitivity, specificity and accuracy in the diagnosis of TMJ disc displacement. It could be a valuable imaging technique in assessing TMJ disc position. The diagnostic value of high-resolution ultrasonography depends strictly on the examiner’s skills and on the equipment used.
