The Le Fort I osteotomy, originally performed for their maxillary dentoalveolar hypoplasia, was an incomplete osteotomy. It was performed without down-fracture, leaving the pterygomaxillary and septal junctions intact. The gradual advancement of the maxilla during distraction osteogenesis was planned to correct the hypoplastic maxilla, and also prevent subsequent hypernasality; however, during the distraction procedure by means of a rigid external device both patients developed an unintentional facial advancement at the Le Fort III level.232052 bytesapplication/pdfenElsevierCleft lipCleft palateLe Fort IIIMaxillary distractionCleft palate -- Surgery -- South AfricaMouth -- Surgery -- Complications -- South AfricaPostprint Article
