title: Composite tissue allotransplantation for the reconstruction of congenital craniofacial defects.
abstract: Facial disfigurement in children with congenital craniofacial defects can lead to decreased self-esteem and poor self-perception. Traditional methods of reconstruction can fail to achieve a normal appearance in patients with severe disfigurements. Composite tissue allotransplantation (CTA) in children could offer a unique reconstructive opportunity. A discussion of the usage of CTA for congenital craniofacial defects is thus warranted. Treatment of severe craniofacial clefts, Treacher-Collins syndrome, hemifacial microsomia, and some vascular anomalies can yield unsatisfactory results, even after multiple surgeries. CTA provides the advantage of intact vascularized bone that would not need to be reshaped to fit the defect, with the correct donor match. CTA also provides reconstruction with similar tissue type in regions of the central midface such as the nose, lips, and eyelids. With advances in transplant immunology to devise mechanisms to decrease immunosuppression and induce donor antigen-specific tolerance, CTA may be a future reality in the pediatric population.
