Distraction Osteogenesis of Costocartilaginous Rib Grafts and Treatment Algorithm for Severely Hypoplastic Mandibles

Abstract

For the severely hypoplastic mandibles (Pruzansky type III), costocartilaginous grafts are an accepted modality. However, when rib graft growth is insufficient, secondary distraction should be performed within the native mandible or rib graft and not at the rib graft-mandible junction site.
