Two children who had cleft lip and palate with severe maxillary hypoplasia were treated by maxillary distraction osteogenesis. They underwent a high Le Fort I osteotomy and maxillary advancement with distraction osteogenesis, performed with the use of an external, adjustable, rigid distraction device (Rigid External Distraction (RED) System®). The skeletal and soft-tissue midface defects were improved. Their occlusion was also corrected. This report describes the surgical technique, application procedure, and preoperative and postoperative management for the RED System.
