The purpose of this study was to test the statistical relationship between certain preoperative characteristics of the maxilla and nasal cavity and later occlusal development in patients born with complete unilateral cleft lip and palate. The sample consisted of 51 patients and 22 of them had undergone surgical treatment which included vomer flap and pushback palatal repair, while the remaining 29 patients were treated with a routine characterized by delayed closure of the hard palate. Twelve variables related to 4 different maxillary and nasal areas were recorded from maxillary casts and frontal cephalograms obtained in infancy. Crossbite scores and maxillary intercanine width were determined from dental casts taken at 3 years of age. Multiple linear regression analysis showed that the preoperative variables selected as predictors of maxillary development at the age of 3 did not explain more than half of the variation found in our subjects. Also, the predictors were not the same in the two surgical subgroups. To improve our ability to predict, further variables should be tested and, if possible, added to the regression formulae.
本研究的目的是测试完全性单侧唇腭裂患者上颌骨和鼻腔的某些术前特征与后期咬合发育之间的统计关系。样本包括51例患者，其中22例接受了手术治疗，包括犁骨瓣和后推腭裂修复术，其余29例患者接受了以硬腭延迟关闭为特征的常规治疗。从婴儿期获得的上颌模型和头颅正位片记录了与4个不同上颌和鼻腔区域相关的12个变量。根据3岁时所取的牙模确定反咬合分数和上颌尖牙间宽度。多元线性回归分析表明，所选作为3岁时上颌发育预测指标的术前变量，在我们的研究对象中所解释的变异不到一半。此外，两个手术亚组中的预测指标也不相同。为提高我们的预测能力，应测试更多变量，并在可能的情况下将其添加到回归公式中。
