“…Increase in resolution increased the sensitivity of US. Emshoff et al, used a transducer of 7.5 MHz, with which the sensitivity was found to be 41-50% and specificity was 70% [28], while in other studies where the transducer used was of 10MHz or more, sensitivity was the limited accessibility of the deep structures, especially the disc, due to the absorption of sound waves by the lateral portion of the head of the condyle and the zygomatic process of the temporal bone [26].…”

“…Several studies discuses the role of ultrasound in assessment of anterior disc displacement [14][15][16][17][18]. Meta-analysis of diagnosis efficacy of ultrasound in assessment of anterior disc displacement reported that diagnostic efficacy of disc displacement with reduction had a sensitivity of 0.76, a specificity of 0.82, a positive likelihood ratio of 3.80, a negative likelihood ratio of 0.36, a diagnostic odds ratio of 10.95, an area under the curve of 0.83, and a Q* of 0.76.…”

“…High-resolution ultrasound was used for assessment of the anterior disc displacement of TMJ [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. All these studies discuss the anterior displacement of the TMJ without assessment of sideway displacement of the disc.…”

Purpose To assess pattern of articular disc displacement in patients with internal derangement (ID) of temporomandibular joint (TMJ) with ultrasound. Materials and methods Prospective study was conducted upon 40 TMJ of 20 patients (3 male, 17 female with mean age of 26.1 years) with ID of TMJ. They underwent highresolution ultrasound and MR imaging of TMJ. The MR images were used as the gold standard for calculating sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), and negative likelihood ratio (NLR) of ultrasound for diagnosis of anterior or sideway displacement of the disc. Results The anterior displaced disc was seen in 26 joints at MR and 22 joints at ultrasound. The diagnostic efficacy of ultrasound for anterior displacement has sensitivity of 79.3 %, specificity of 72.7 %, accuracy of 77.5 %, PPV of 88.5 %, NPV of 57.1 %, PLR of 2.9 and NLR of 0.34. The sideway displacement of disc was seen in four joints at MR and three joints at ultrasound. The diagnostic efficacy of ultrasound for sideway displacement has a sensitivity of 75 %, specificity of 63.6 %, accuracy of 66.7 %, PPV of 42.8, NPV of 87.5 %, PLR of 2.06, and NLR of 0.39. Conclusion We concluded that ultrasound is a non-invasive imaging modality used for assessment of anterior and sideway displacement of the articular disc in patients with ID of TMJ.Riassunto Scopo Valutare i pattern della dislocazione del disco articolare nei pazienti con squilibrio interno (ID) dell'articolazione temporo-mandibolare (ATM) con l'ecografia. Materiale e metodi E' stato condotto uno studio prospettico su 40 ATM di 20 pazienti (3 maschi, 17 femmine, con età media di 26,1 anni) con ID della TMJ. Tutti sono stati sottoposti ad ecografia ad alta risoluzione e RM della TMJ. La RM è stati utilizzata come il gold standard per il calcolo di sensibilità, specificità, accuratezza, valore predittivo positivo (PPV), valore predittivo negativo (NPV), rapporto di probabilità positivo (PLR) e rapporto di probabilità negativo (NLR) dell'ecografia nella la diagnosi di dislocazione anteriore o lateralmente del disco. Risultati Il disco appariva dislocato anteriormente in 26 ATM con la MR e in 22 con l'ecografia. L'efficacia diagnostica dell'ecografia nella diagnosi di dislocazione anteriore aveva sensibilità del 79,3 %, specificità del 72,7 %, accuratezza del 77,5 %, valore predittivo positivo del 88,5 %, NPV di 57,1 %, PLR di 2,9 e NLR di 0,34. Il dislocamento laterale del disco è stata osservato in 4 casi con MR e 3 con ecografia. L'efficacia diagnostica dell'ecografia per lo spostamento laterale aveva sensibilità del 75 %, specificità del 63,6 %, accuratezza del 66,7 %, PPV di 42,8, NPV di 87,5 %, PLR di 2.06 e NLR di 0,39. Conclusioni Abbiamo concluso che l'ecografia è una metodica di imaging non invasiva che può essere utilizzata per la valutazione delle dislocazioni anteriori e laterali del disco articolare nei pazienti con ID di TMJ.

“…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].…”

“…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.
