不同病程的单侧ADDWOR患者关节间隙及骨性结构特征分析OA
Analysis of joint spaces and osseous structure characteristics in patients with unilateral ADDWOR at different disease stages
目的:分析不同病程的单侧不可复性关节盘前移位(anterior disc displacement without reduction,ADDWOR)患者的颞下颌关节间隙及骨性结构特征.方法:本研究为横断面探索性研究,纳入 92 例单侧 ADDWOR患者,根据病程分为 3 组:A 组 31 例(病程≤3 个月),B 组 31 例(3 个月<病程≤6 个月),C 组 30 例(病程>6 个月),收集并比较 3 组患侧颞下颌关节的前间隙、上间隙、后间隙、关节窝深度、关节窝长度、髁突宽度、髁突长度、髁突高度、关节结节倾斜度、髁突形态和髁突位置.结果:前间隙及上间隙方面,A 组>B 组>C 组,且 C 组与 A 组、B 组之间均具有显著差异(P<0.05),但 A 组与 B 组无明显统计学差异(前间隙:PA-B=0.761;上间隙:PA-B=0.150).就后间隙而言,A 组<B 组<C 组,C 组与 A 组、B 组之间差异均具有统计学意义(P<0.05),但 A 组与 B 组无明显统计学差异(PA-B=0.696).髁突位置方面,B 组及 C 组的前位及中间位占比较 A 组增加,而后位较 A 组减少,但差异无统计学意义(P=0.094).髁突宽度、髁突长度、髁突高度、关节窝深度、关节窝长度或关节结节倾斜度均无统计学显著差异(P>0.05).此外,髁突形状方面也未发现统计学显著差异(P>0.05).结论:不同病程 ADDWOR 患者的关节间隙存在显著差异,但髁突、关节窝、关节结节等骨性结构无显著差异.未来仍需通过纵向、大样本量研究进一步揭示ADDWOR 病程中骨性结构的动态改变.
Objective:This study aimed to analyze the temporomandibular joint spaces and osseous structure in pa-tients with unilateral anterior disc displacement without reduction(ADDWOR)at different disease stages.Methods:In this exploratory cross-sectional study,92 patients with unilateral ADDWOR were enrolled and divided into three groups based on disease duration:Group A(31 cases with disease duration≤3 months),Group B(31 cases with disease duration between 3 and 6 months),and Group C(30 cases with disease duration>6 months).The anterior,superior,and posterior joint spaces,glenoid fossa depth and length,condylar width,length,and height,articular eminence inclination,condylar shape,and condy-lar position on the affected side were measured and compared among the three groups.Results:For the anterior and superior spaces,Group A>Group B>Group C,with significant differences observed between Group C and both Groups A/B(all P<0.05).However,there was no statistically significant difference between Group A and Group B(anterior space:PA-B=0.761;superior space:PA-B=0.150).Regarding the posterior space,Group A<Group B<Group C.The differences between Group C and both Groups A/B were statistically significant(all P<0.05),while no significant difference was found between Group A and Group B(PA-B=0.696).In terms of condylar position,Group B and Group C showed an increase in the proportion of an-terior and central positions and a decrease in the proportion of posterior position compared with Group A.However,the differ-ence was not statistically significant(P=0.094).No statistically significant differences were detected in condylar width,length,and height,glenoid fossa depth and length,or articular eminence inclination(all P>0.05).Furthermore,no statistical-ly significant difference was found in condylar shape among the three groups(P>0.05).Conclusion:Patients with ADDWOR at different disease stages show significant differences in joint spaces,but no significant differences in the bony structures of the condyle,glenoid fossa,and articular eminence.Future longitudinal,large-scale studies are still needed to fur-ther elucidate the dynamic bony structural changes during the course of ADDWOR.
