摘要: 正常的关节盘–髁突关系对于颞下颌关节的健康十分重要,它的改变在临床上具有重要意义。磁共振成像(MRI)被认为是颞下颌关节盘–髁突关系紊乱及软组织形态成像的金标准,被广泛地用于颞下颌关节特征的评估、协助诊断以及治疗方式的选择中。目前多数研究表明颞下颌关节紊乱病(TMD)早期阶段可能表现为关节盘的前外侧移位、双凹形态的改变。关节盘形态、位置的改变进一步导致髁突长度、高度及旋转角度等发生变化,使疾病向更严重的阶段发展。TMD患者关节盘的位置和形态改变、髁突的解剖学变化与关节盘移位具有相关性,被认为引起是TMD最常见的原因。

Abstract: A normal articular disc-condyle relationship is important to the health of temporomandibular joint. The change of articular disc-condyle is of great clinical significance. Magnetic resonance imaging (MRI) is considered as the gold standard of temporomandibular joint disc-condyle relationship disorder and soft tissue morphology imaging, and is widely used in the evaluation of temporomandibular joint characteristics, diagnosis assistance and treatment choice. At present, most studies show that the early stage of temporomandibular joint disorder(TMD) may be characterized by anterolateral displacement of the joint disc and changes in the shape of biconcave. Changes in the shape and position of the articular disc further lead to changes in the length, height and rotation angle of condyle, which makes the disease develop to a more serious stage. The position and shape changes of joint disc and the anatomical changes of condyle in TMD patients are related to the displacement of joint disc, which is considered to be the most common cause of TMD.

Key words: Temporomandibular joint disorder, Magnetic resonance imaging, Articular?disc?, Condyle
