The purpose of this study was to investigate the effects of two-stage palatoplasty combined with Hotz' plate on sagittal mid-facial development in complete unilateral cleft lip and palate (UCLP) individuals.Materials and Methods:The subjects selected for this study were 72 Japanese individuals (age: 9-19 years) divided into Group A (two-stage palatoplasty) consisting of 24 UCLP subjects (12 females and 12 males), Group B (one-stage palatoplasty) consisting of 24 UCLP subjects (12 females and 12 males), Group C (control group) consisting of 24 non cleft subject (12 females and 12 males) who had Class I skeletal relation. The investigation of soft tissue morphology was carried out using a three-dimensional surface scanner (VIVID 700, Minolta. co) and an analyzing soft ware. The 9 corresponding facial measurement points were obtained by intersection of the following planes; 3 vertical planes parallel to mid-sagittal planes through entocanthion, pupulare and ectocanthion, 3 horizontal planes parallel to Frankfort plane through ear rod, alare and mid-point ear rod and alare, respectively. Mid-facial sagittal growth was determined by evaluating the difference of z-coordinates values of 9 corresponding facial measurement points between both sides for each cleft group and between right and left sides for control group. Both side in the cleft group and in the control group were evaluated by student's t-test. The differences among the three groups were statistically compared by ANOVA.Results:The chi-square test using scores gained by each group, revealed significant difference among three groups. Mid-facial sagittal growth was similar on cleft side and non-cleft side or right and left side in two-stage group and control group. Mid facial sagittal growth on non-cleft side was bigger than cleft side in one-stage group.Conclusion:Cleft patients, who undertook two-stage palatoplasty showed a better sagittal mid-facial development than the one with one-stage palatal closure.

本研究的目的是探讨两期腭成形术联合霍茨钢板对完全性单侧唇腭裂（UCLP）患者矢状面中部发育的影响。材料与方法：选取年龄9-19岁的日本人72例，分为A组（两期腭裂成形术）24例（男女各12例），B组（一期腭裂成形术）24例（男女各12例），C组（对照组）24例（男女各12例），均为ⅰ类骨骼关系的非腭裂患者。使用三维表面扫描仪（VIVID 700，美能达）进行软组织形态学研究。Co)和一个分析软件。通过以下平面相交得到9个对应的面部测量点；3个垂直平面分别通过耳杆、耳杆和中点耳杆、耳杆平行于中矢状面，3个水平面分别通过耳杆、耳杆和耳杆平行于法兰克福平面。通过评估面部两侧9个相应面部测量点的z坐标值之差来确定面部中矢状面生长情况。裂隙组和对照组的两侧均采用学生t检验进行评价。三组间差异采用方差分析进行统计学比较。结果：用各组所得分数进行卡方检验，三组间差异有统计学意义。两期组和对照组的面中矢状面生长与非裂侧或左右侧相似。一期组非裂侧面部正中矢状面生长大于裂侧。结论：两期腭裂患者面中矢状面发育优于一期腭裂患者。
