From: Reconstruction of an iatrogenic anterior conchal defect with a revolving-door flap

Fig. 1

A 24-year-old female presented with an anterior conchal skin and cartilage defect after rhinoplasty with a conchal cartilage graft. A revolving-door (RD) flap was performed to cover the anterior conchal defect as a single-stage procedure. a Preoperative view of the anterior conchal skin and cartilage defect. b Intraoperative view: the flap, which was divided into retroauricular (A, red arrow) and mastoid (B, red arrow) parts by the cephalon-auricular sulcus (dashed blue lines), was dissected around the periphery and elevated along a deep plane. Its base was left unattached at the cephalon-auricular sulcus to maintain the completeness of the vascular pedicle (beneath dashed blue lines), which contained tributaries of the posterior auricular artery (PAA). A through-and-through opening space was ready to be created for transposition of the flap, as shown by the dashed yellow lines. c Parts A and B of the flap were rotated approximately 180° and 30° on its vertical axis, respectively, and pulled through the defect from the distal edge to cover the anterior conchal defect. Part A (red arrow) of the flap settled at the medial half of the conchal defect, and part B (red arrow) covered the lateral half of the defect. d Oblique view of the concha one day postsurgery. The flap survived completely, without total or partial failure. e Posterior view, one day postsurgery. The donor site was closed with interrupted mattress sutures. f Results 6 months after the surgery. There were no obvious scars or retraction at the recipient site
