The temporomandibular joint (TMJ) is a common site of complaint. Clicking sounds and pain are indicators of a frequent condition called internal derangement, most often affecting females. As a general term, internal derangement describes a structural abnormality within an articulation. The internal derangement of the TMJ is a specific term defined as an abnormal positional and functional relationship between the disk and articulating surfaces. Imaging of the joint is an important element in the diagnostic work-up. Trauma and inflammatory arthritis account for most of the other TMJ problems. A thorough understanding of joint anatomy and normal function is a prerequisite for perceiving abnormalities and making the correct diagnosis. The authors elucidate joint anatomy, correlating cadaveric specimen and anatomic slices with conventional and cross-sectional imaging studies. TMJ biomechanics are illustrated with schematics and animations, and an overview of imaging strategies and techniques is presented. Common abnormalities are described and illustrated, and a brief discussion of therapeutic options is included.
颞下颌关节（TMJ）是常见的不适部位。弹响和疼痛是一种名为关节内紊乱的常见病症的指标，该病症最常影响女性。作为一个通用术语，关节内紊乱描述了关节内的结构异常。颞下颌关节的关节内紊乱是一个特定术语，定义为关节盘与关节面之间异常的位置和功能关系。关节成像在诊断检查中是一个重要因素。创伤和炎性关节炎是大多数其他颞下颌关节问题的病因。透彻了解关节解剖结构和正常功能是察觉异常并做出正确诊断的先决条件。作者阐述了关节解剖结构，将尸体标本和解剖切片与传统及横断面成像研究进行了对比。用示意图和动画展示了颞下颌关节生物力学，并概述了成像策略和技术。描述并展示了常见异常情况，还包括对治疗选择的简要讨论。
