Facial artery perforator flap for reconstruction of perinasal defects: An anatomical study and clinical application.

Background: The concept of the facial artery perforator flap was developed for improved freedom during the reconstruction of perioral and perinasal defects. This flap enables tailor-made reconstruction and a shift from the traditional two-stage procedure to a one-stage technique. In this cadaveric study, the authors quantify the number, length, and diameter of facial artery perforators (FAPs) and present their clinical experience with the FAP flap.
