This study is to evaluate the growth and development of the maxilla advanced by transoral distraction osteogenesis of cleft lip and palate children. Subjects are two patients diagnosed as maxillary hypoplasia with cleft lip and palate, and followed up over 5 years after distraction. At the age of 11.4 years (mean), the distraction had been rendered and periodically taken lateral cephalograms were analysed to trace the growth of the maxilla. This cephalometric study showed continuous growth and development of the distracted maxilla to be stable through long term follow-up.
