The paper explains the alterations of the temporomandibular joint (TMJ) visualized by magnetic resonance imaging (MRI) according to the growth and development of schoolchildren. Appearance and disappearance of a "double contour-like structure" (DCLS) of the mandibular condyle on MRI according to the growth and development of schoolchildren were demonstrated. In addition, possible constituents of DCLS and the significance of detection of DCLS on MRI were also speculated. The relationship between red marrow and yellow marrow in the articular eminence of temporal bone, the disappearance of DCLS, and alterations of the mandibular condyle have been elucidated.
本文根据学龄儿童的生长发育情况，解释了通过磁共振成像（MRI）观察到的颞下颌关节（TMJ）的变化。展示了根据学龄儿童的生长发育，下颌髁突在MRI上“双轮廓样结构”（DCLS）的出现和消失。此外，还推测了DCLS的可能组成成分以及在MRI上检测到DCLS的意义。阐明了颞骨关节结节中红骨髓与黄骨髓的关系、DCLS的消失以及下颌髁突的变化。
