摘要： 目的 探讨替牙期单侧完全性唇腭裂（unilateral complete cleft lip and palate, UCLP）患者鼻上颌复合体在三维方向上的对称性。方法 选择20例替牙期UCLP患者颅面部锥形束CT（CBCT）图像,运用Mimics 图像分析软件对骨组织进行三维重建,描记鼻根点及鼻上颌复合体健、患侧32个同名标记点,建立三维参考平面、分别测量32个点到三维平面的距离。采用SPSS 22.0 软件包对数据进行统计学分析。结果 在水平方向上,与非裂隙侧相比,裂隙侧点INM 、SPC处上颌骨的宽度小,点LPA、SPr处上颌骨宽度大,差异具有统计学意义（P<0.05)。在矢状方向上,与非裂隙侧相比,裂隙侧点LPA、Maz、SPr处深度大,点SPM、SPC处深度小,差异具有统计学意义（P<0.05)。在垂直方向上,裂隙侧点LPA、INM、Maz低于非裂隙侧,点SPC、SPr高于非裂隙侧,差异具有统计学意义（P<0.05)。其余各点均无统计学差异（P>0.05)。结论 替牙期UCLP患者鼻上颌复合体在三维方向上均不对称,不对称部位集中在鼻腔和牙槽骨处。眶部及远离裂隙的上颌骨区域未发现明显不对称。

Abstract: PURPOSE: To investigate the symmetry of nasal maxillary complex in the three-dimensional directions of patients with unilateral complete cleft lip and palate(UCLP) at the stage of mixed dentition. Methods: Craniofacial cone-beam CT(CBCT) images of 20 UCLP patients at the stage of mixed dentition were selected. Three-dimensional reconstruction of bone tissue was carried out by Mimics software, nasal root point and 32 markers with the same name of the healthy side and the cleft side of the nasal maxillary complex were traced, three-dimensional reference planes were set up, then the distances between the points to the three-dimensional planes were measured respectively. SPSS 22.0 software package was used to analyze the data. Results: In the horizontal direction, compared with the non-cleft side, the width of the cleft side of the maxilla at INM and SPC was smaller, the width of maxilla at LPA and SPr was larger, the differences were statistically significant (P<0.05). In the sagittal direction, compared with the non-cleft side, the depth of LPA, Maz and SPr at the cleft side was larger, the depth of SPM and SPC was smaller, the differences were statistically significant (P<0.05).In the vertical direction, the positions of LPA, INM and Maz at the cleft side was lower than the non-cleft side, SPC and SPr were higher, the differences were statistically significant(P<0.05). The remaining points had no significant difference (P>0.05). Conclusions: The nasal maxillary complex of UCLP patients at the stage of mixed dentition is asymmetric in three directions. The asymmetric locations were mainly located in the nasal cavity and alveolar bone. No obvious asymmetry is found in the orbital region and the maxillary region far from the cleft.
