O-X Flap; Quadripolar Advancement Flap / 대한피부과학회지

ABSTRACT

Large surgical defects are often difficult to repair and extensive adjacent skin transfer may be necessary. The purse-string suture can be used to reduce the size of large defects, but a second intervention may be necessary and requires several weeks for complete healing. Therefore, reconstruction of large defects is a challenge to the dermatologist. We report a case of basal cell carcinoma on the back in which the skin defect was reconstructed by a quadripolar advancement flap. Because the large O-shaped defect resulted in an X-shaped closure, we named this flap the O-X flap.
