Maxillary distraction osteogenesis is an important technique to treat maxillary hypoplasia. Recently, the novel technique of maxillary distraction with a rigid external distraction device (RED system) was proposed by Polley and Figueroa. This technique involves gradual advancement of the maxilla after Le Fort I osteotomy.
We successfully treated an 18-year-old man who had maxillary deficiency with a hyperplastic mandible by both maxillary distraction and sagittal split ramus osteotomy. The maxillary incisors had been severely retroclined. The patient had bilateral cross-bite, a 20-mm anterior cross-bite, and class III molar occlusion.
This report describes our treatment of the patient with the use of an external, adjustable, rigid distraction device.
