From the American Society for Dermatologic Surgery: Management of Alopecia of the Scalp by a Combination of Excisions and Transplantations

Abstract

Since the number of grafts that are available in any given patient is a fixed quantity, significant benefits may be derived by surgically reducing the size of the area of alopecia in combination with prior and later punch hair transplantation. This paper outlines and describes techniques of excisions that achieve such reductions.
