REVASCULARIZED BONE-GRAFTS FOR CRANIOFACIAL RECONSTRUCTION

Reconstruction of craniomaxillofacial defects caused by injury, tumor ablation, or congenital deformities can be accomplished by a variety o f methods. Nonvascularized (free), vascularized (pedicled), and revasc ularized (microvascular) bone grafts have been employed for osseous re storation of the upper, mid, and lower facial skeleton. In comprised r ecipient tissue beds or when rapid functional restoration is desired, revascularized flaps hold certain advantages over their nonrevasculari zed counterparts. The revascularized flaps used most commonly for cran iofacial reconstruction are discussed with regard to anatomy, clinical applications, and aesthetic and functional limitations.
