Abstract
This study was designed to evaluate the correlations between the morphology and growth of cranial base and the position of nasomaxillary complex and mandible in complete unilateral cleft lip and palate patients. Craniofacial skeletal morphology pattern was analyzed on the lateral cephalometric radiographs of the 100 subjects of complete unilateral cleft lip and palate group and the 100 normal grower group and each group was divided three sub-groups by age-range like spheno-ethmoidal synchodrosis growing group, spheno-occipital synchondrosis growing group and finished synchondrosis growth group. These data were statistically analyzed to examine significant difference between both groups and between each sub-groups.
The results of this study were as follows:
1. In complete unilateral cleft group, the length, thickness of clivus, and the rate of increase in length of clivus showed smaller amount by adolescence. The anterior length of cranial base and the rotation pattern of clivus with age showed no significant difference between two group.
2. In complete unilateral cleft group, nasomaxillary complex were located more posteriorly. This difference between two groups is larger by adolescent group than adult. Vertical position showed no significant difference between two gi oups. There was significant correlation between the cranial base of cleft group and the horizontal measurements(p<0.01). PtmS showed no significant increment in cleft group. This showed the deficiency of growth in posterior part of maxilla. .
3. In mandible, there was no significant difference between normal group and complete unilateral cleft group but articular angle showed significantly smaller in cleft group than in normal one. And the measurements of nasomaxillary complex position, cranial base and the position of mandible had significant correlation(p<0.01).
