Abstract
Background: The purpose of the present study was a three-dimensional evaluation of the spheno-occipital synchondrosis (SOS) and zygomatico-maxillary suture (ZMS) in cleft lip and palate patients versus the normal population. Materials and Methods: In the case-control study, cone beam computed tomography scans of 153 unilateral or bilateral cleft lip and palate patients and 153 scans of healthy non-cleft individuals with skeletal Class I occlusion from 6 to 18 years were selected. Then the ZMS and SOS maturation stages were determined. Mann-whitney test, spearman correlation, repeated measurement, and bayesian transition analysis were used for statistical analysis. P-value 0.05). Conclusion Maturation of zygomatico-maxillary suture in cleft lip and palate was earlier than non-cleft children, however sphenooccipital synchondrosis did not show any significant differences in maturational stages between cleft lip and palate patients and healthy controls.
