Decreased joint space is one of the basical radiographic signs of joint disease and correlation with crepitus the real clinical symptom of structural joint damage. The aim of this investigation is to find out if there is any correlation between the intrajoint condyle position and joint dysfunction symptomatology, by means of TMJ tomography evaluation. Among the patients with characteristic symptoms of TMJ dysfunction examined in our Departments, a group of hundred were tomographed (Polytom--Philips-Massiot). Thirty students not showing any anamnestic or clinical symptoms formed the control group. In the evaluation of radiographic findings we accepted the static relation between condyle and glenoid fossa in the maximal intercuspal position, where the joint space was divided in three almost equal parts. The radiographic findings of the relationship between condyle and glenoid fossa in the maximal intercuspal position are presented on with the intention of establishing the most characteristic differences between the groups. The statistical elaboration has been carried out by multivariante analysis of variance. The characteristic radiographic findings in our group of patient are: --excentric condyle position, --posterior condyle displacement and --marked asymmetry. Therefore, these findings represent efficient aid in TMJ dysfunction diagnosis, and show direction for repositioning of condyle in therapy dysfunction.
关节间隙变窄是关节疾病的基本影像学征象之一，且与关节摩擦音相关，而关节摩擦音是关节结构损伤的实际临床症状。本研究的目的是通过颞下颌关节断层扫描评估，找出关节内髁位置与关节功能障碍症状之间是否存在任何关联。在我们科室检查的有颞下颌关节功能障碍特征性症状的患者中，一组100名患者进行了断层扫描（飞利浦 - 马西奥多排螺旋CT）。30名没有任何既往史或临床症状的学生组成了对照组。在评估影像学结果时，我们接受在最大牙尖交错位时髁突与关节窝的静态关系，此时关节间隙被分为大致相等的三部分。展示了最大牙尖交错位时髁突与关节窝关系的影像学结果，目的是确定两组之间最具特征性的差异。通过多变量方差分析进行了统计学处理。我们这组患者的特征性影像学表现为：——髁突偏心位置，——髁突后移位，以及——明显不对称。因此，这些发现对颞下颌关节功能障碍的诊断有有效帮助，并为治疗功能障碍时髁突的重新定位指明了方向。
