“…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.…”

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.

“…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.…”

“…In open mouth position, normalcy is defined by intermediate zone located between the condyle and the articular eminence. [34,36] Razek et al (2015) assessed the pattern of articular disc displacement in patients with internal derangement using US and concluded that the diagnostic efficacy of US for anterior displacement has sensitivity of 79.3%, specificity of 72.7%. [37] Other applications of US Periapical and intraosseous lesions, maxillofacial trauma, detection of foreign bodies, US guided fine needle biopsy, submandibular gland injection of botulinum toxin for hypersalivation in cerebral palsy and in basket retrieval of salivary stones.…”

“…US image of the disc is of a thin homogenous, hypo/isoechoic band whereas mandibular condyle and the articular eminence are appreciated as hyperdense lines. [34,35] In closed mouth position, an intermediate zone of the disc rests between the anterosuperior aspect of the condyle and the posteroinferior aspect of the articular eminence. When located anterior to this position, the disc is regarded as anteriorly displaced.…”

The story of the application of ultrasound (US) in imaging goes back a long way in history. It has been deemed useful in various situations and has evolved over time to a more sophisticated and precise modality. Some of the advances are in the form of newer and more useful equipment increasing its pertinence in dentistry and medicine. Currently, it is being used in various head and neck pathologies owing to its non-invasive nature and has gained wider acceptance in maxillofacial imaging. In this paper we will take a relook of US in areas such as its history, basic principles, advances in the equipment and wide array of applications in head and neck pathologies and also weigh its merits and demerits in specific areas.

“…Another important issue is that US examination is unable to visualize the medial part of the condyle. On the other hand, being a real time investigation, US provides information regarding disc position during mandibular movements, compared to other TMJ imaging techniques [4][5][6].…”

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.
