Distraction osteogenesis quickly has become a mainstay in tile treatment of craniofacial syndromes with mandibular hypoplasia. We report on a series of eight patients undergoing distraction osteogenesis of neomandibles constructed with costochondral grafts. The length of distraction, resting phase between distraction and device removal, and complication rate were significantly greater in the rib-graft distraction group when compared with our series of native mandibular distraction patients (n = 21 devices). Most complications were minor, including pintrack infection and hardware failure; however, major complications included fibrous union and facial nerve praxia. Secondary procedures have been able to be performed successfully on previously distracted rib grafts as well.
