目的：确定单侧唇腭裂婴儿面部不对称的程度，并量化初次手术后的改善，在三个方面。设计：20名单侧唇腭裂婴儿的面部（10个UCL; 10例UCLP）和20例年龄匹配的非唇腭裂对照组，在初次唇/鼻修复前使用C3 D立体摄影测量系统进行拍摄方法：应用Procrustes技术对三维标志点进行镜像成像。计算标志与其对映体之间的均方距离，并表示为每个3D配置的不对称评分。结果：对照组患者术后3个月~ 1年的面部、鼻、唇不对称评分无明显变化。UCLP组比UCL组更不对称，初次修复后鼻对称性改善最大。随着时间的推移，嘴唇继续改善。UCL组有显着的鼻不对称，这似乎并没有改善与primary surgery.CONCLUSIONS：立即改善不对称分数的儿童UCLP与生产一个更对称的鼻型后，主要手术。相比之下，UCL儿童的鼻不对称性即使手术也没有改变。全脸不对称分数可能会掩盖随着时间的推移微妙的变化。鼻和唇的不对称应单独考虑。
OBJECTIVES: To determine the degree of facial asymmetry in infants with unilateral cleft lip and/or palate, and quantify improvements following primary surgery, in three dimensions.DESIGN: The faces of 20 infants with unilateral clefts (10 UCL; 10 UCLP), and 20 age-matched, non-cleft controls, were captured using the C3D stereophotogrammetry system prior to primary lip/nose repair (at 3 months), at 6 months and at age 1 year.METHODS: Procrustes techniques were applied to 3D landmark configurations to its mirror image. Mean squared distances between landmarks and their antimeres were calculated and expressed as asymmetry scores for each 3D configuration. Full-face, nose and lip median scores were compared and changes with time evaluated (P < 0.01).RESULTS: There were no significant changes in asymmetry scores in the control group from 3 months to 1 year. The UCLP group was more asymmetric than the UCL group, displaying greatest improvement in nasal symmetry following primary repair. The lips continued to improve over time. The UCL group had significant nasal asymmetry, which did not appear to improve with primary surgery.CONCLUSIONS: Immediate improvement in asymmetry scores in children with UCLP is related to the production of a more symmetrical nasal form after primary surgery. In contrast, the nasal asymmetry seen in children with UCL is unchanged despite surgery. Full face asymmetry scores may mask subtle changes over time. Nasal and lip asymmetry should be considered individually.
