OBJECTIVE: To investigate whether timing of hard palate repair, before versus after pubertal peak velocity age, had a significant effect on facial growth in patients with unilateral cleft lip and palate.
DESIGN: Retrospective cross-sectional study.
SETTING: Sri Lankan Cleft Lip and Palate Project.
PATIENTS: A total of 125 adult patients with nonsyndromic unilateral cleft lip and palate were recruited and their last cephalometric radiographs were used.
MAIN OUTCOME MEASURES: Clinical notes were used to record surgical treatment histories. Cephalometry was used to determine facial morphology.
RESULTS: The patients who had hard palate repair after pubertal peak velocity age had a deeper bony pharynx (Ba-PMP), a longer alveolar maxilla (PMP-A), a longer effective length of the maxilla (Ar-ANS, Ar-A), and as a result had a more favorable anteroposterior jaw relation (ANS-N-Pog, ANB, NAPog) and larger overjet, compared with those who had hard palate repair before pubertal peak velocity age.
CONCLUSION: Timing of hard palate repair significantly affects the growth of the maxilla in patients with unilateral cleft lip and palate. Hard palate repair after (versus before) pubertal peak velocity age has a smaller adverse effect on the forward growth of the maxilla. This timing affects the forward displacement of the basal maxilla and the anteroposterior development of the maxillary dentoalveolus.
