Целью данного исследования явилось определение диагностической ценности ультразвукового метода обследования в комплексной диагностике внутренних нарушений ВНЧС. В качестве референсного метода диагностики использовалась магнитно-резонансная томография. В исследование были включены 33 пациента (30 женщин и трое мужчин, средний возраст 35,4 года, всего 62 сустава). Всем пациентам была проведена ультразвуковая диагностика ВНЧС высокого разрешения в положении с закрытым ртом и во время максимально возможного открывания рта. УЗИ и МРТ проводились двумя независимыми специалистами в области заболеваний ВНЧС.
Objective. The purpose of this study was to determine the diagnostic value of dynamic high-resolution sonography in the evaluation of internal derangements (ID) of the temporomandibular joint (TMJ) compared to magnetic resonance imaging (MRI) with the mouth closed and during the maximal mandibular range of motion. Materials and methods. Prospective study was conducted upon 62 TMJ of 33 patients (3 males, 30 females with a mean age of 35.4 years) with TMJ disorders. All the patients underwent high-resolution ultrasound and MR-imaging of TMJs with the mouth closed and during the maximal mandibular range of motion. The MR images were used as the gold standard for calculating sensitivity, specificity, accuracy and negative predictive value (NPV) of ultrasound for diagnosis of the anterior disc displacement. Both examinations were performed and interpreted independently by blinded expert operators. Results. Magnetic resonance imaging depicted 9 normal joints (14.52 %) and 40 joints (64.51 %) with the anterior disc displacement. Sonography depicted 2 normal joints (3.22 %) and 60 joints (96.78 %) with the anterior disc displacement. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) for the diagnosis of anterior disc displacement were 100 %, 9.09, 67.74 66.66 and 100% respectively. Conclusion. Dynamic high-resolution sonography is a potential non-invasive imaging method for assessment of the TMJ anterior disc displacement and degenerative diseases. However, further studies are needed for sonography diagnostic value specification.
