Abstract | OBJECTIVE: Evaluate impact of single-stage versus staged palate repair on the risk of developing malocclusion among patients with cleft palate (CP). DESIGN: Retrospective cohort study 2000-2016. SETTING: Academic, tertiary children's hospital. PATIENTS: Patients undergoing CP repair between 1999-2015. INTERVENTIONS: CP repair, categorized as either single-stage or staged. MAIN OUTCOME MEASURE: Time to development of Class III malocclusion. RESULTS: 967 patients were included; 60.1% had a two-stage CP repair, and 39.9% had single-stage. Malocclusion was diagnosed in 28.2% of patients. In the model examining all patients at ≤5 years ( = 659), patients who were not white had a higher risk of malocclusion (HR 2.46, = 0.004) and staged repair was not protective against malocclusion (HR 0.98, = 0.91). In all patients >5 years ( = 411), higher Veau classification and more recent year of birth were significantly associated with higher hazard rates ( < 0.05). Two-staged repair was not protective against developing malocclusion (HR 0.86, = 0.60). In the model examining patients with staged repair ≤5 years old ( = 414), higher age at hard palate closure was associated with reduced malocclusion risk (HR 0.67, < 0.001) and patients who were not white had increased risk (HR 2.56, = 0.01). In patients with staged repair >5 years old, more recent birth year may be associated with a higher risk of malocclusion (HR 1.06, = 0.06) while syndrome may be associated with lower risk of malocclusion diagnosis (HR 0.46, = 0.07). CONCLUSION: Our data suggests that staged CP repair is not protective against developing Class III malocclusion. |
