目的:形态学研究是前椎间盘移位(ADD)病理学领域的一种常见方法;然而,基于3D重建成像的分析尚未得到研究。这项研究调查了ADD与下颌髁突和关节窝状态之间的关系。
方法:34例患者分为正常关节盘位置(NADP)组,减少增加(ADDwR)组,和不减少的ADD(ADDwoR)组。重建的图像用于确定这三种不同类型的椎间盘位置的多个分组比较,并对具有显著分组差异的形态学参数的诊断效能进行分析评估。
结果:NADP的髁突体积和髁浅表面积,ADDwR,ADDwoR组出现明显变化(P<0.05)。多元logistic序数回归模型显示,髁突体积(比值比[OR],1.011;回归系数[RC]=.011,P=.018),上关节空间(或,8.817;RC=2.177;P<.001),和内侧关节间隙(OR,1.492;RC=0.400;P=0.047)对各组有显著的正向影响。
结论:颞下颌关节ADD中的下颌髁突和关节窝表现出尺寸改变。髁的体积,髁浅表区,优越的关节空间,内侧关节间隙可以被认为是评估ADD的有前途的生物识别标记,并在目前的试点研究中进行了调查。(QuintessenceInt2023;54:156-166;doi:10.3290/j。齐。b3512027)。
OBJECTIVE: Morphologic
study is a common approach in the field of anterior disc displacement (ADD) pathology; however, analysis based on 3D reconstructive imaging has not been investigated. This
study investigated the association between ADD and the status of the mandibular condyle and articular fossa.
METHODS: Thirty-four patients were divided into a normal articular disc position (NADP) group, an ADD with reduction (ADDwR) group, and an ADD without reduction (ADDwoR) group. Images reconstructed were used to determine multiple grouped comparisons of these three different types of disc position, and the diagnostic efficacy for the morphologic parameters with significant grouped difference was analyzed to assess.
RESULTS: The condylar volume and condylar superficial area of the NADP, ADDwR, and ADDwoR groups exhibited obvious changes (P < .05). A multivariate logistic ordinal regression model showed that the condylar volume (odds ratio [OR], 1.011; regression coefficient [RC] = .011, P = .018), superior joint space (OR, 8.817; RC = 2.177; P < .001), and medial joint space (OR, 1.492; RC = 0.400; P = .047) had a significantly positive impact on the groups.
CONCLUSIONS: The mandibular condyle and articular fossa in temporomandibular joint ADD exhibited altered dimensions. The condylar volume, condylar superficial area, superior joint space, and medial joint space could be considered as promising biometric markers for assessing ADD, and were investigated in this current pilot
study. (Quintessence Int 2023;54:156-166; doi: 10.3290/j.qi.b3512027).
