A three-dimensional measuring system was developed to analyze changes in palatal forms of UCLP infants. This system quantified the change of the curved surface on a palate by automatically superimposing two wireframe models obtained from casts at different stages of growth. It also analyzed the curvature of the palatal surface. This system was used to study the palates of 20 infants with unilateral cleft lip and palate (UCLP), from the first to fourth months after birth (12 with Hotz's plate and 8 without, selected at random). Both major and lesser maxillary segments without Hotz's plate remained anterior and lateral although those with Hotz's plate moved mesially during the fourth month after birth. In addition, the degrees of curvature on the palatal surfaces with Hotz's plate were less than those without Hotz's plate.
开发了一种三维测量系统，以分析单侧唇腭裂（UCLP）婴儿腭部形态的变化。该系统通过自动叠加在不同生长阶段从模型获得的两个线框模型，量化腭部曲面上的变化。它还分析了腭面的曲率。该系统用于研究20名单侧唇腭裂婴儿从出生后第一个月到第四个月的腭部情况（随机选择12名使用霍茨板的婴儿和8名未使用霍茨板的婴儿）。未使用霍茨板的上颌主要和次要节段均保持在前部和外侧，而使用霍茨板的节段在出生后第四个月向近中移动。此外，使用霍茨板的腭面曲率程度小于未使用霍茨板的腭面曲率程度。
