The objectives of the study were to introduce and investigate the reliability of a new flap for postauricular defects using the retroauricular artery perforator.Twenty auricles from 10 Asian human cadavers were dissected to examine the retroauricular perforator distribution and diameter. Fourteen patients with postauricular defects underwent reconstruction using the retroauricular artery perforator from 2013 to 2015. After locating the position of the perforator by ultrasound Doppler blood flow detection, a suitable flap was designed according to the defect's size, condition, and distance from the pedicle. The flap was meticulously elevated, rotated appropriately, and sutured to the defect. The donor site was then closed.Cadaver dissection showed that the posterior auricular artery produces at least 2 constant branches with an external diameter of 0.84 ± 0.25 mm at the origin. These branches proceed toward the mastoid process at the height of the auriculocephalic angle to nourish the skin and fascia. A total of 14 clinical cases were available for 3 to 12 months postoperative follow-up. All flaps survived completely, maintaining good skin color, perfect outer contour, and complete patient satisfaction with the aesthetic results after initial treatment.Retroauricular artery perforator-based island flaps appear to be ideal for 1-stage reconstruction of postauricular skin defects.
