Free-flap Reconstruction of Large Defects of the Scalp and Calvarium

Beyond a certain size, full-thickness defects of scalp are not amenable to local flap repair. Staged distant flaps have now been virtually eliminated by free-flap reconstruction. The authors present 12 patients in whom full-thickness scalp defects with an average area of 275 cm2 were reconstructed utilizing free flaps. Nine patients had corresponding large calvarial defects. Ten patients had reconstruction with free latissimus dorsi muscle flaps and overlying skin grafts, and one patient had reconstruction with a scapular free flap. Of the 12 patients, 8 had extirpative surgery for tumor with immediate reconstruction and the remaining 4 had reconstruction for chronic radionecrosis of the scalp, usually associated with infected osteoradionecrosis of the calvarium. Of this latter group, 2 patients underwent simultaneous acrylic cranioplasty. The technique and results are discussed.
