The deformities of the head or neck are often the result of trauma, oncologic resection, infection, osteoradionecrosis, and congenital or developmental pathology. Multiple tissue types that compose the craniofacial region including bone, cartilage, nerve, fat, muscle, mucosa, and varying dermal and epidermal thickness, as well the inherently intricate contours of the craniofacial skeleton can complicate reconstruction. The introduction and refinement of free tissue transfer (FTT), combined with microvascular anastomosis, allows major ablative defects to be reliably reconstructed with a single...
