Abstract

Introduction: Management of temporomandibular joint (TMJ) osteoarthritis (OA) is a challenging issue in modern gnathology and maxillofacial surgery. Identifying various signs of TMJ OA, their relationship with internal derangement and studying the features of combined (uni-, bilateral) pathology contribute to an accurate assessment of TMJ condition and appropriate management. Conventionally, besides clinical examination, this state was diagnosed by computed tomography. However, magnetic resonance imaging (MRI) allows the assessment of both bone and soft tissue. The aim of the study was to identify the correlation between degenerative changes in bone structures and various forms of internal TMJ disorders based on MRI data, as well as to assess the morphofunctional changes in the TMJ in cases of uni-, bilateral joint pathology.

Materials and methods: Two hundred and twenty-two patients (444 joints) underwent a clinical examination and MRI of the TMJ (Siemens Magnetom Verio MRI scanner Germany 3.0 T). Exclusion criteria included systemic diseases, joint trauma and prior treatments.

Results: Osteodegeneration predominated in cases of anterior disc displacement without reduction (ADDWoR): osteophytes on the condylar head (74.8%), flattening (40.2%), erosions (31.8%) and subchondral sclerosis (88.8%). As the degree of disc displacement progressed, the decrease of volume of condyle, changed from 373.8 mm² with normal disc position (NDP) to 251.3 mm² with ADDWoR. In cases with NDP, unilateral OA was present in 2.3% of and bilateral OA in 4.1%. Bilateral displacement is characterised by bilateral OA in 26.1%, whereas unilateral OA in 12.2%. There is a positive correlation between the position of the disc in the sagittal projection and degenerative changes.

Discussion: Strong correlation was identified between degenerative changes in the bone structures of the TMJ and various types of internal disorders.

磁共振成像对颞下颌关节内部紊乱和骨关节炎的前瞻性研究。

简介：颞下颌关节（TMJ）骨关节炎（OA）的治疗是现代颌面外科和颌面外科的一个具有挑战性的问题。识别TMJ骨性关节炎的各种征象及其与内部紊乱的关系，研究联合（单侧、双侧）病理特征，有助于准确评估TMJ病情并进行适当的治疗。通常，除临床检查外，该状态可通过计算机断层扫描诊断。然而，磁共振成像（MRI）可以评估骨骼和软组织。本研究的目的是基于MRI数据确定骨结构退行性改变与各种形式的TMJ内部疾病之间的相关性，并评估单侧、双侧关节病理情况下TMJ的形态功能变化。材料与方法：222例患者（444个关节）行TMJ临床检查和MRI （Siemens Magnetom Verio德国3.0 T MRI扫描仪）。排除标准包括全身性疾病、关节创伤和既往治疗。结果：前椎间盘不复位移位（ADDWoR）以骨变性为主：髁突头骨赘（74.8%）、变平（40.2%）、糜烂（31.8%）和软骨下硬化（88.8%）。随着椎间盘移位程度的加深，髁突体积的减少从正常椎间盘位置（NDP）时的373.8 mm2变为ADDWoR时的251.3 mm2。在NDP病例中，单侧OA占2.3%，双侧OA占4.1%。双侧移位的特点是双侧OA占26.1%，而单侧OA占12.2%。矢状面椎间盘的位置与退行性改变呈正相关。讨论：TMJ骨结构的退行性改变与各种类型的内部疾病之间存在很强的相关性。
