Figure 1: Ultrasound imaging of the articular disc at the temporomandibular area. The probe was placed in a transverse plane slightly anterior to the temporomandibular joint. (a) When the jaw was closed, the articular disc, a hypoechoic structure, was located anterior to the mandibular condyle. (b) When the jaw was opened, the disc shifted superiorly and posteriorly and disappeared from the ultrasonography imaging field. Mas: masseter, Cor: Coronoid process of mandible, Ant: Anterior, Post: Posterior, D: Articular disc, Con: Mandibular condyle
