With the use of multilevel modeling of longitudinal data, the relationship between the developmental status of the palate at 4 years of age and early palatal growth and development from birth to 1.5 years of age was studied. A model to predict palatal depths and widths at 4 years of age was developed and tested. The sample consisted of 130 children with cleft lip and/or palate. They were divided into three groups according to surgical treatment; (1) no palatal surgery, (2) soft palatal surgery, and (3) soft and hard palatal surgery. Results showed that in groups 1 and 2, the total arch depth at 4 years of age is strongly related to the initial arch depth at birth. No or low correlations were found between palatal depth at 4 years of age and the growth velocity at birth. The anterior arch width in groups 2 and 3 at 4 years of age appeared to be strongly related to the early growth velocity. In group 1, a moderate correlation with the palatal width and growth velocity at birth was observed. The results of the individual predictions of arch depths and arch widths were reasonable to fair. It was concluded that prediction of individual arch variables at 4 years of age is possible, although within limits. Clinically this means that extreme development can be discriminated from more average development.
通过使用纵向数据的多水平模型,研究了4岁时腭部的发育状况与从出生到1.5岁时早期腭部生长发育之间的关系。开发并测试了一个预测4岁时腭部深度和宽度的模型。样本包括130名唇裂和/或腭裂儿童。他们根据手术治疗分为三组:(1)未进行腭部手术,(2)软腭手术,(3)软硬腭手术。结果显示,在第1组和第2组中,4岁时的总牙弓深度与出生时的初始牙弓深度密切相关。4岁时的腭部深度与出生时的生长速度之间未发现或仅发现低相关性。第2组和第3组中4岁时的前牙弓宽度似乎与早期生长速度密切相关。在第1组中,观察到与出生时的腭部宽度和生长速度存在中等相关性。牙弓深度和牙弓宽度的个体预测结果合理到尚可。得出的结论是,尽管有一定局限性,但4岁时个体牙弓变量的预测是可能的。临床上这意味着可以区分极端发育与更一般的发育情况。
