Abstract

This study aimed to use new three-dimensional (3D) anthropometric analyses to verify the post-surgical effects on the maxillary segments of children with unilateral cleft lip and palate. The sample was composed by digitized dental models of 60 children with unilateral complete cleft lip and alveolus (UCLA) and complete unilateral cleft lip and palate (UCLP). The impressions were taken before cheiloplasty (T1), after cheiloplasty (T2), and after palatoplasty (T3). The 3D anthropometric analyses of digitized dental casts were obtained through a specific software. Intragroup changes were applied paired t test and Wilcoxon test (UCLA group) and for the UCLP group, repeated-measures analyses of variance followed by the Tukey test. For intergroup analyses, an independent t test and Mann-Whitney test were used. The palatal dimensional changes of UCLA group showed that the distances IC, I-T', and I-T significantly increased after cheiloplasty (p = 0.0002, p = 0.0007 and p < 0.0001, respectively). In the UCLP group, the IC' distance statistically decreased in the post-surgical periods (p < 0.0001), while the I-T distance increased (p < 0.0001). The IC distance increased after cheiloplasty (p < 0.0001). The I-T' distance increased betwee...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
