title: Mandibular lengthening by distraction osteogenesis in the setting of osteogenesis imperfecta.
abstract: Osteogenesis imperfecta (OI) is an inherited disorder characterized by bone fragility and deformity. The craniofacial skeleton may be involved either primarily or by result of a concomitant diagnosis. Distraction osteogenesis has emerged as a versatile reconstructive option for many craniofacial deformities. Mandibular lengthening by distraction has not been reported in a patient with OI. We present a patient in whom mandibular lengthening was successfully performed twice for hemifacial microsomia. Bilateral lengthening was initially performed with successful airway improvement. This was followed by transport distraction on the more severely affected side for condylar reconstruction. Successful mandibular lengthening by distraction is possible in the setting of OI.
