Scalp and calvarial reconstruction.

Over the past several decades, an improved understanding of the blood supply of local flaps, increased experience with tissue expansion, and the development of techniques for microsurgical transfer of distant flaps have greatly contributed to the ability of plastic surgeons to repair scalp defects. This article will review basic anatomy, principles, and pearls of reconstruction for simple to complex scalp defects. Included will be anatomic considerations, indications and contraindications for reconstruction, and an overview of reconstructive options.
