Bifocal transport osteogenesis for the reconstruction of adult calvarial defects: a new surgical technique.

Calvarial defects are common problems in craniofacial surgery. They may be explained by surgical interventions, infectious processes, cranial trauma or congenital anomalies. Calvarial defects are particularly challenging because they do not heal spontaneously in humans older than 24 months. The feasibility of using bifocal transport distraction osteogenesis to repair calvarial defects has been successfully evaluated in numerous experimental models. To our knowledge, it has not been used for the reconstruction of human skull defects. We report the first case of human calvarial defect healed by transport distraction osteogenesis.
