目的：本研究探讨颏偏颌下颌不对称患者的特征与颞下颌关节（TMJ）椎间盘状况的关系，包括正常椎间盘位置（NDP）、前位椎间盘移位伴复位（ADDwR）、旋转椎间盘移位伴复位（RDDwR）、前位和/或旋转椎间盘移位不复位（DDwoR）。材料与方法：86例心理偏差患者，其中女性62例，男性24例。TMJ磁共振图像分为4组：双侧ndp （n = 15）、ADDwR （n = 13）、RDDwR （n = 19）和DDwoR （n = 39）。采用后前位和侧位脑电图确定下颌偏位和上下颌不对称的特征。统计分析各组间头颅测量变量的差异。结果：骨骼ⅰ类、骨骼ⅱ类关系下思维偏差的患者在侧位头颅片上DDwoR的发生率较高。两组患者在前后脑位平片上的下颌平面夹角和颏偏度有显著性差异。这两个变量在DDwoR组明显大于双侧ndp组。结论：前后颌关系和下颌偏位可能与颞下颌关节盘移位的严重程度有关。
Purpose: This study investigated the relationships among characteristics of maxillomandibular asymmetry in patients with menton deviation and temporomandibular joint (TMJ) disc conditions, including normal disc position (NDP), anterior disc displacement with reduction (ADDwR), rotational disc displacement with reduction (RDDwR), and anterior and/or rotational disc displacement without reduction (DDwoR).Materials and methods: Eighty-six patients with menton deviation (62 female patients and 24 male patients) were included. The TMJ magnetic resonance images were categorized into four groups: bilateral-NDP (n = 15), ADDwR (n = 13), RDDwR (n = 19) and DDwoR (n = 39). The characteristics of menton deviation and maxillomandibular asymmetry were determined using posteroanterior and lateral cephalograms. Differences in cephalometric variables among the groups were statistically analysed.Results: Patients with menton deviation under Skeletal Class I, and Skeletal Class II relationship showed a higher rate of DDwoR on lateral cephalograms. Significant differences were detected among groups on posteroanterior cephalograms with respect to the cant of the frontal mandibular plane and menton deviation. These two variables were significantly greater in the DDwoR group than in the bilateral-NDP group.Conclusion: The anteroposterior jaw relatioship and mandibular deviation may be associated with the severity of TMJ disc displacement.
