摘要
目的:目前对不同年龄单侧完全性唇腭裂(unilateral complete cleft lip and palate,UCLP)患者双侧颞下颌关节对称性的研究结果仍存在争议,本实验通过分析不同发育时期UCLP患者髁突在关节窝中的位置和髁突形态,探讨其对称性的差异,为UCLP患者序列治疗提供新的理论依据。方法:选取90例UCLP患者,按照年龄及牙列发育分为替牙列组(31例)、年轻恒牙列组(31例)、年长恒牙列组(28例)。将锥形束CT(cone beam computed tomography,CBCT)影像导入Invivo 5软件进行三维重建,测量髁突在关节窝中的位置、髁突高度、内外径和前后径,并计算其不对称性指数。结果:各组间髁突高度和前后径的不对称性指数从小到大依次为替牙列组<年轻恒牙列组<年长恒牙列组(均P<0.05);替牙列组与年轻恒牙列组髁突内外径和不对称性指数差异均无统计学意义(均P>0.05),且均小于年长恒牙列组(均P<0.05)。与正常侧相比,各组裂隙侧髁突高度均偏小(均P<0.05);替牙列组裂隙侧关节前间隙偏小(P<0.05)、关节后间隙偏大(P<0.05)。结论:随年龄增长,UCLP患者髁突形态不对称性逐渐加重,但位置正常,提示早期治疗对UCLP患者颞下颌关节形态发育具有重要的临床意义。
Objective:Currently,the research results regarding the bilateral temporomandibular joint symmetry in patients at different ages with unilateral complete cleft lip and palate(UCLP)are still controversial.In this study,the position of condyle in the articular fossa and morphology of condyle in UCLP patients at different developmental stages was measured and analyzed to explore the asymmetry difference,which can provide a new theoretical basis for the sequential therapy.Methods:A total of 90 patients with UCLP were divided into a mixed dentition group(31 cases),a young permanent dentition group(31 cases)and an old permanent dentition group(28 cases)according to age and dentition development.Cone beam computed tomography(CBCT)images were imported into Invivo5 software for 3D reconstruction,and the joint space,anteroposterior diameter,medio-lateral diameter,and height of condylar were measured,and its asymmetry index was calculated.Results:The asymmetry index of condylar height and anteroposterior diameter among the 3 groups,from small to large,was the mixed dentition group<the young permanent dentition group<the old permanent dentition group(both P<0.05).There was no significant difference in condylar anteroposterior diameter and asymmetry index between the mixed dentition group and the young permanent dentition group(both P>0.05),all of them were lower than those in the old permanent dentition group(both P<0.05).Compared with the normal side,the height of fracture condyle was smaller among the 3 groups(all P<0.05),and the anterior joint space was smaller(P<0.05)and the posterior joint space was larger(P<0.05)in the mixed dentition group.Conclusion:In patients with UCLP,the asymmetry of condylar morphology increases with age,but the condylar position tends to normal.These results suggest that early treatment has important clinical significance for the morphologic development of temporomandibular joint in UCLP patients.
