Craniofacial features of operated unilateral complete cleft lip and palate children: a case control study
OBJECTIVE: To compare the craniofacial features of Brazilian children who had received surgery for unilateral complete cleft lip and palate compared with non-cleft group.METHODS: Craniofacial features were evaluated on lateral cephalometric radiographs. 46 patients with unilateral complete cleft lip and palate were divided by gender and matched at ages 6, 7, 8 and 9. They were compared with 46 non-cleft children, equally divided by gender and matched the same age groups. All comparisons were carried out by means of the Angles SNA, SNB and ANB. The findings were analyzed on the basis of the two-way Analysis of Variance (ANOVA) with p <0.05 significance level.RESULTS: Both the angle SNA and SNB in the cleft group had a lower average in both genders and all age groups compared with the non-cleft group (p<0.0001). The average values of ANB were significantly higher in the cleft group (p<0.05) both in males and females and in all age groups studied.CONCLUSION: Children who had received surgery for unilateral complete cleft lip and palate during childhood had maxillary and mandibular retrusion and a class II skeletal pattern in relation to non-cleft group.
