We describe post-total maxillectomy secondary facial contour reconstruction using an osteocutaneous scapular flap nourished by flow-through vascularization from the radial vascular system. Scar contracture caused by either total or partial maxillectomy for maxillary cancer was completely released with exposure of the edge of the zygomatic arch, orbital floor, and nasal bone. The scapular skin flap was placed into the mucosal defect, and the orbital floor and zygomatic prominence were reconstructed with the scapular bone. The flap nutrient vessels were anastomosed to radial vessels and cephalic vein grafts. Two representative cases are illustrated to demonstrate the application and advantage of this operative method.
