【摘要】：目的：借助磁共振技术,对不同临床表现的可复性盘前移关节的盘髁角度、关节盘形态及关节渗出情况进行统计分析,为早期发现需要治疗的可复性盘前移关节提供参考。方法：收集25例(30侧关节)经MRI证实为可复性盘前移患者,初诊时详细记录病史和颞下颌关节专科检查情况,予开闭口斜冠状位、矢状位T2WI和PDWI扫描。根据患者主观感受和专科检查结果,将所有关节分为弹响疼痛组(A组)和无症状组(B组)。对闭口斜矢状位盘髁角度进行测量,记录关节盘形态和关节渗出等级,采用SPSS20.0软件包对源数据进行T检验和费歇尔概率法检验。结果： A、B组均可见关节渗出,但A组关节渗出发生率更高,以中等量渗出为主,存在统计学差异(P0.05)。A组关节盘前移角度为52.56±15.5°,B组关节盘前移角度为36.62±10.9°,A组关节盘前移程度高于B组,存在统计学差异(P0.05)。A、B两组的关节盘形变发生率没有统计学差异(P0.05),关节盘形态改变以拉长形最多见(47.6%),其次为后带增宽(28.6%) 结论：MRI中关节渗出量、关节盘前移程度与临床症状有关。
[Abstract]:Objective: With the aid of magnetic resonance imaging (MRI), the condylar angle, the shape of disc and the exudation of the disc anterior displacement joints with different clinical manifestations were statistically analyzed, which could provide a reference for the early detection of the reducible disc anterior joints that need treatment. Methods: A total of 25 cases of 30 joints confirmed by MRI as reducible disc anterior displacement were collected. The history of the disease and the special examination of temporomandibular joint were recorded in detail at the first visit, and the oblique coronal position, sagittal position and PDWI scan were performed on the open and closed oblique coronal position and sagittal position. All the joints were divided into group A and group B according to the subjective feeling of the patients and the results of the special examination. The condyle angle of closed oblique sagittal disc was measured and the joint disc shape and joint exudation grade were recorded. The source data were tested by T-test and Fischer probabilistic test by SPSS20.0 software package. Results: The incidence of joint exudation was higher in group A than in group A, with moderate exudation. There was statistical difference between group A and group A (52.56 卤15.5 掳). The degree of anterior displacement of disc in group A was 36.62 卤10.9 掳and that in group A was higher than that in group B. There was no significant difference in the incidence of disc deformation between the two groups (P0.05, P 0.05, P 0.05, P 0.05). The most common morphological changes of the articular disc were elongated, followed by the extension of the posterior band and the extension of the posterior band, 28. 6%) (P < 0. 05, P < 0. 05, P = 0. 05, P < 0. 05). Conclusion the amount of exudation and the degree of anterior displacement of the disc are related to the clinical symptoms.
