In subjects with orofacial clefts, there is an unresolved controversy on the effect of congenital maxillary growth deficiency vs. the effect of surgical intervention on the outcome of treatment. Intrinsic growth impairment in subjects with orofacial clefts can be studied by comparing facial morphology of subjects with untreated cleft and unaffected individuals of the same ethnic background. Bilateral cleft lip and palate is the most severe and least prevalent form of the orofacial cleft. The aim of this study was to compare facial morphology in subjects with unrepaired complete bilateral clefts and unaffected controls using geometric morphometrics. Lateral cephalograms of 39 Indonesian subjects with unrepaired bilateral complete cleft lip and alveolus (mean age: 24 years), or unrepaired bilateral complete cleft lip, alveolus, and palate (mean age: 20.6 years) and 50 age and ethnically matched controls without a cleft (25 males, 25 females, mean age: 21.2 years) were digitized and traced and shape variability was explored using principal component analysis, while differences between groups and genders were evaluated with canonical variate analysis. Individuals with clefts had a more pronounced premaxilla than controls. Principal component analysis showed that facial variation in subjects with clefts occurred in the anteroposterior direction, whereas in controls it was mostly in the vertical direction. Regression analysis with group, sex, and age as covariates and principal components from 1 to 6 as dependent variables demonstrated a very limited effect of the covariates on the facial shape variability (only 11.6% of the variability was explained by the model). Differences between cleft and non-cleft subjects in the direction of facial variability suggest that individuals with bilateral clefts can have an intrinsic growth impairment affecting facial morphology later in life.

PURPOSE: Our aim was to evaluate the dental arch relationship in a preadolescent Slavic population with unilateral cleft lip and palate (UCLP) by using the Goslon Yardstick. MATERIALS AND METHODS: Patients treated in Warsaw, Poland (n = 32), Prague, Czech Republic (n = 33) and Bratislava, Slovakia (n = 30) were included in this retrospective study. Each cleft center used a unique surgical protocol. Three raters scored blindly the dental arch relationship on plaster models. Intra- and inter-rater agreement were assessed with kappa statistics, and differences between the groups were evaluated with one-way analysis of variance. Intra-rater agreement was very good (k > 0.825), while inter-rater agreement was either good or very good (kappa >0.703). RESULTS: We found that patients treated in Warsaw showed a more favorable dental arch relationship (Goslon score = 2.58, SD = 0.77) than patients treated in Prague (Goslon score = 3.21, SD = 1.04). Patients treated in Bratislava showed an intermediate Goslon score (3.07; SD = 0.99). CONCLUSION: This study showed that the dental arch relationships in patients treated in Warsaw with a one-stage repair were more favorable than in patients treated in Prague and Bratislava with a two-stage protocol and comparable to the best results obtained in the Eurocleft and Americleft studies.
