Abstract

Nowadays, patients have high expectations when it comes to minimization of postoperative scarring after dermatologic surgical procedures. When an annular lesion is being excised, normal skin should be excised, as well, to prevent a dog ears resulting in a long scar. We introduce a new flap reducing the scar length in annular defects. In order to avoid a long scar, we designed a quadruple fan flap (O-X flap) that is a variation of the rotation flap. It consists of four rotation flaps arranged like fans, with open and closed configuration. We suggest that the quadruple fan flap (O-X flap) is a viable option for treating annular skin defects, because it shortens the scar line, preserves normal tissue, and provides a cosmetically favorable outcome.
