Abstrakt		Objective: To compare palatal dimensions in six-year-olds with unilateral cleft lip and palate (UCLP) treated by different protocols with those of non-cleft children. Design: Retrospective intercenter outcome study. Patients: Upper dental casts from 129 children with repaired UCLP and 30 controls were analyzed by the trigonometric method. Setting: Six European cleft centers. Main outcome measures: Sagittal, transverse and vertical dimensions of the palate were observed. Statistics: Palate variables were analyzed with descriptive methods and nonparametric tests. Regarding several various characteristics measured on a relatively small number of subjects, hierarchical, k-means clustering and principal component analysis were used. Results: Mean values of the observed dimensions for five cleft groups differed significantly from the control (p<.05). The group with one-stage closure of the cleft differed significantly from all other cleft groups in most variables (p<.05). Principal component analysis of all 159 cases identified three clusters with specific morphological characteristics of the palate. A similar number of treated children were classified into each cluster, while all children without clefts were classified in the same cluster. The percentage of treated children from a particular group that fit this cluster ranged from 0 to 70% and increased with age at palatal closure and number of primary surgical procedures. Conclusion: At six years, children with stepwise repair and hard palate closure after age two more frequently result in palatal dimensions of noncleft control than children with earlier palatal closure and one-stage cleft repair.
