用电磁仪对18例唇腭裂白人患者(男11例，女7例，年龄19~27岁)和161例健康对照组(女73例，男，年龄18~30岁)进行了面部软组织标志的三维坐标数字化处理。通过检测左右两侧面部的对称面和重心(CG)，并通过计算两个CG之间的距离(DFS)来量化面部不对称性。获得绝对(毫米)和百分比(重心距离)DFS。对单个地标的不对称性也进行了量化。总体而言，手术治疗的CLP患者的不对称性仅比健康参考人群的测量结果略大，最大值仅比最大正常不对称性大5%。女性患者比男性患者有更大的侧向不对称，单侧CLP患者(尤其是男性)比双侧CLP患者更不对称。8例鼻前区和鼻下区的标志不对称，而所有患者的棘突、颧部、唇部和生殖器的标志是对称的。总而言之，与年龄、性别和种族相同的参照组相比，成年手术的CLP患者面部软组织结构仅略有不对称。
The three-dimensional coordinates of 23 selected soft-tissue facial landmarks were digitized on 18 cleft lip and palate (CLP) white patients (11 male and 7 female patients aged 19-27 years) and 161 healthy controls (73 female and 89 male subjects aged 18-30 years) by an electromagnetic instrument. Facial asymmetry was quantified by detecting a plane of symmetry and the centers of gravity (CG) of the right and left hemifaces and by calculating the distance between the two CG (distance from symmetry [DFS]). Both absolute (millimeters) and percentage (of the nasion center of gravity distance) DFS was obtained. The asymmetry of single landmarks was also quantified. Overall, asymmetry in operated CLP patients appeared only moderately larger than that measured in the healthy reference population, with the largest value being only 5% larger than the maximum normal asymmetry. Female patients had a somewhat larger lateral asymmetry than male patients, and unilateral CLP patients (particularly the men) were more asymmetrical than bilateral CLP patients. Pronasale and subnasale landmarks were asymmetrical in 8 patients, whereas endocanthion, zygion, cheilion, and gonion landmarks were symmetrical in all patients. In conclusion, the facial soft-tissue structures of CLP patients operated on as adults were only moderately more asymmetrical than those measured in a reference group of the same age, sex, and ethnicity.
