               [摘   要] 目的:探讨单侧颞下颌关节不可复性盘前移位(anterior disc displacement without reduction,ADDWoR)患者下颌偏斜
                发生率及影像特征,并分析影响下颌偏斜的相关因素。方法:回顾性纳入2020年4月—2023年12月于南京医科大学附属口腔医
                院口腔颌面外科就诊的210例单侧ADDWoR患者,按是否有下颌偏斜分为偏斜组和对照组,通过锥形束CT(cone beam computed
                tomography,CBCT)分析下颌骨形态与位置特征,通过磁共振成像评估关节盘特点,采用多因素Logistic回归分析影响下颌偏斜
                的相关因素。结果:210例患者中偏斜组104例,年龄为18.0(13.0,34.3)岁,对照组106例,年龄为27.0(15.0,54.0)岁。偏斜组
                表现为患侧下颌骨升支高度及体部长度均显著小于健侧,下颌整体向患侧后上方旋转,即患侧前/后间隙比值、健侧外间隙、健
                侧上间隙增大,患侧外间隙、健侧前/后间隙比值缩小;偏斜组关节盘长度更短且与髁突顶距离更远。青少年偏斜组除了下颌
                骨形态和位置的变化外,关节盘位置也发生明显改变,但成年人偏斜组关节盘形态和位置无明显变化。多因素Logistic回归分
                析显示,下颌骨位置(患侧前/后间隙比值、患侧外间隙、健侧前/后间隙比值、健侧上间隙)及下颌骨形态(下颌升支高度差、下
                颌体部长度差)是下颌偏斜的独立影响因素(P均< 0.05)。结论:单侧ADDWoR相关下颌偏斜与下颌骨形态及位置改变密切相
                关,患侧下颌骨矢状向长度缩短及下颌整体向患侧后上方旋转可能是下颌偏斜的主要原因,青少年ADDWoR患者更易出现下
                颌骨形态、位置及关节盘状态的显著变化。

                A study on the correlation between unilateral temporomandibular joint anterior disc
                displacement without reduction and mandibular deviation

               [Abstract] Objective:To investigate the incidence and radiographic characteristics of mandibular deviation in patients with
                unilateral anterior disc displacement without reduction(ADDWoR)of the temporomandibular joint,and to analyze the related factors
                influencing mandibular deviation. Methods:This retrospective study enrolled 210 patients with unilateral ADDWoR who visited the
                department of oral and maxillofacial surgery,the Affiliated Stomatological Hospital of Nanjing Medical University between April 2020
                and December 2023,which were divided into a deviation group and a control group based on whether there was mandibular deviation.
                Cone⁃beam computed tomography(CBCT)was used to analyze mandibular morphology and positional characteristics,while magnetic
                resonance imaging assessed disc features. Multivariate logistic regression analysis was employed to identify factors associated with
                mandibular deviation. Results:Among the 210 patients,104 were assigned to the deviation group[median age 18.0(13.0,34.3)years]
                and 106 to the control group[median age 27.0(15.0,54.0)years]. The deviation group demonstrated significantly reduced ramus height
                and body length on the affected side compared to the unaffected side,with the entire mandible exhibiting posterior⁃superior rotation
