本文总结了157例颞颔关节紊乱综合征(TMJDS)弹响患者的临床和X线诊断资料,目的在于探讨弹响的病因机制、病程特点及规律。根据薛氏位平片(187侧弹响关节)与关节上腔造影(94侧弹响关节)的X线征象,并结合临床病史与各项检查,证实弹响多为 TMJDS 的初发症状,多具有不同程度的关节内结构和(或)器质病变,并以盘前移位和(或)髁后移位最常见。弹响的性质时程与关节内病变的类型、程度密切相关,病程进展与关节内病变的发展相对应,有较明显的临床阶段性特征。弹响主要是由于咬合、肌肉异常因素的影响,最终形成关节内病变所致。
This article summarizes the clinical and X-ray diagnostic data of 157 patients with TMJ syndrome snapping. The purpose is to investigate the etiopathogenisis, duration characteristics and regularity of snapping sound. According to the X-ray findings of Hysteroplasty (187 side snapping joints) and articular superior chamber contrast (94 side snapping joints) combined with clinical history and various examinations, it was confirmed that snapping mostly was the initial symptom of TMJDS, More with varying degrees of intra-articular structures and / or organic lesions, and to disc displacement and (or) posterior condylar displacement of the most common. Sluggish nature of the time course and the type of joint disease, the degree is closely related to the progression of disease and the development of intra-articular lesions corresponding to a more obvious clinical stage characteristics. Snapping is mainly due to bite, the impact of abnormal muscle factors, resulting in the formation of intra-articular lesions.
