Study Summary

Patients with cleft lip and palate frequently develop Class III (Cl III) malocclusions or underbites following early cleft repair surgeries. This clinical trial compares the current standard of care for treating the Cl III malocclusion, orthognathic (jaw) surgery after pubertal growth (16-21 years), with an alternative orthopedic approach to protract the maxilla during adolescence (11-14 years). At Children's Hospital Los Angeles(CHLA), early adolescents with cleft lip and palate and Cl III malocclusion are offered an alternative non-surgical approach to correct the malocclusion called "maxillary protraction". Prior to age 14, the maxillary sutures have not fused and can be mobilized by alternating weekly expansion and constriction with a rapid palatal expander (RPE), thereby allowing the upper jaw (maxilla) to be pulled forward (protracted) to correct the underbite. This prospective parallel cohort study will assess the patients undergoing treatment for the Cl III malocclusion by either orthognathic surgery or maxillary protraction at four data collection time points during treatment. The data includes digitized study models, photographs and radiographs, quality of life surveys (SF12, YQOL), parent surveys (ASEBA), treatment cost, periodontal measurements and treatment complications. The study design is a descriptive cohort study that examines the success of treatment (% not requiring a second surgery), the dental and skeletal changes associated with treatment, the stability of treatment and the behavioural/adaptive factors (ASEBA) that contribute to success and lack of success for each treatment. The primary trial will be conducted at Children's Hospital Los Angeles and a pilot study to confirm translation to different settings will be conducted at Seattle Children's Hospital.

Primary Outcome

The metric for comparing the difference in bite using study models from patients with cleft lip and palate is the "GOSLON Yardstick" which can rate antero-posterior as well as transverse positions.
