Study Population: The inclusion criteria are patients who are diagnosed with isolated cleft lip and palate with Cl III malocclusion and who, at the time of enrollment, do not have any medical condition which will prevent them from undergoing orthognathic surgery or maxillary protraction procedures. The two study groups differ in age and treatment. One group of patients, ages 11 -14 years of age, chose to undergo maxillary protraction via sutural loosening for correction of Cl III malocclusion. The other group of patients, ages 16 and 21 years, elected to undergo orthognathic surgery for correction of Cl III malocclusion.
