Distraction osteogenesis of zygomatic bone grafts in a patient with Treacher Collins syndrome: a case report.
Zygomatic aplasia in patients with Treacher Collins syndrome requires reconstruction with autogenous bone grafts. Serial bone grafting may be required if optimal malar projection is not achieved with the initial procedure. This report demonstrates the use of distraction osteogenesis in repositioning a previously bone-grafted zygoma in an adolescent patient with Treacher Collins syndrome, thus avoiding the need for repeat bone graft harvest. The limitations of this technique include difficulty in achieving the desired vector of distraction and the potential of graft devitalization. Nevertheless, the case report illustrates the versatility of distraction osteogenesis in skeletal augmentation/remodeling.
