“…Although it has been suggested that ultrasonography can detect different abnormalities in the TMJ such as condylar erosions, synovial thickening and effusion, 13 most authors consider the examination to be non-specific. The hypoechoic area between the condyle and the capsule contains fluid, synovium and the disc, and the differentiation between those structures is difficult.…”

“…Ultrasonography examinations were performed on Philips HDI 5000 (Philips, Eindhoven, Netherlands), Philips iU22 (Philips) or Siemens S3000Ô (Siemens, Erlangen, Germany) with high-frequency linear probes (12)(13)(14)(15)(16)(17)(18). Two experienced musculoskeletal radiologists (EK and RBG), aware of age and gender, analyzed the ultrasonography images separately, blinded to the MRI observations.…”

“…A more recent study concluded that ultrasonography could become "one of the leading instruments" for the evaluation of TMJ involvement in JIA. 13 In adults, ultrasonography of other TMJ-related diagnoses, mostly disc displacement and degenerative joint disease, have been promising. 14,15 The purpose of our study was to explore the ability of ultrasonography to detect inflammatory activity in the TMJ in children with rheumatic disease compared with MRI.…”

Objectives: Ultrasonography is an effective, low-cost, low-threshold and convenient diagnostic tool in childhood arthritis, but its value in temporomandibular joint (TMJ) involvement is not clear. The purpose of our study was to explore the reliability of ultrasonography to assess TMJ inflammation using contrast-enhanced MRI as reference standard, in order to deduce cut-off values for TMJ capsular width to detect enhanced synovial thickening (synovitis). Methods: 124 ultrasonography and MRI examinations in 55 patients [mean age 12.4 ± 3.5 years (±standard deviation)], the majority obtained within 1 day, were scored for subcondylar and condylar capsular width (ultrasonography images) and amount of synovitis (MR images). The correlations of these findings were calculated. A receiver operating characteristic (ROC) curve analysis, with MRI findings as reference standard, was obtained. Results:The correlation between ultrasonography-assessed capsular width and MRIassessed amount of synovitis was moderate both at the subcondylar and condylar level [Spearman's rho (r): 0.483; p , 0.001 and 0.347; p , 0.001 respectively]. The ROC curve indicated the best discriminatory ability at the subcondylar level with an area under the curve of 0.77 (95% confidence interval 0.69-0.85) and a cut-off value of 1.2 mm (sensitivity 72%, specificity 70%) for the capsular width. Conclusions: A moderate correlation between ultrasonography-assessed capsular width and MRI-assessed synovitis was found in childhood arthritis with the best discriminatory ability at the subcondylar level. This indicates that ultrasonography may be a valuable diagnostic tool in the initial assessment of TMJ inflammation.

“…The application of cone beam CT (CBCT) to craniofacial imaging provides a clear visualization of the hard tissues of TMJ and markedly reduces radiation and cost compared with medical CT. [13][14][15][16][17][18][19][20][21][22][23] The Osteoarthritis Initiative, a National Institutes of Health-sponsored consortium, focused on identifying imaging biomarkers of development and progression of knee OA using MRI. 24 Although ultrasound and MRI are effective in monitoring synovitis, [25][26][27] MRI and panoramic radiography have poor to marginal sensitivity in detecting arthritic bony changes in TMJ. 11 CBCT has recently replaced other imaging modalities and become the modality of choice to study TMJ arthritic bony changes because it provides high-quality images for quantification of bone changes, such as erosions, osteophytes, flattening, sclerosis and abnormal condylar shape.…”

Objectives: To investigate the reliability of regional three-dimensional registration and superimposition methods for assessment of temporomandibular joint condylar morphology across subjects and longitudinally. Methods: The sample consisted of cone beam CT scans of 36 patients. The across-subject comparisons included 12 controls, mean age 41.3 ± 12.0 years, and 12 patients with temporomandibular joint osteoarthritis, mean age 41.3 ± 14.7 years. The individual longitudinal assessments included 12 patients with temporomandibular joint osteoarthritis, mean age 37.8 ± 16.7 years, followed up at pre-operative jaw surgery, immediately after and one-year post-operative. Surface models of all condyles were constructed from the cone beam CT scans. Two previously calibrated observers independently performed all registration methods. A landmark-based approach was used for the registration of across-subject condylar models, and temporomandibular joint osteoarthritis vs control group differences were computed with shape analysis. A voxel-based approach was used for registration of longitudinal scans calculated x, y, z degrees of freedom for translation and rotation. Two-way random intraclass correlation coefficients tested the interobserver reliability. Results: Statistically significant differences between the control group and the osteoarthritis group were consistently located on the lateral and medial poles for both observers. The interobserver differences were #0.2 mm. For individual longitudinal comparisons, the mean interobserver differences were #0.6 mm in translation errors and 1.2°in rotation errors, with excellent reliability (intraclass correlation coefficient .0.75). Conclusions: Condylar registration for across-subjects and longitudinal assessments is reliable and can be used to quantify subtle bony differences in the three-dimensional condylar morphology.
