The reverse auricular flap: a new flap for nose reconstruction.

In the present article, the authors describe a new chondrocutaneous island flap from the ear helix for nose reconstruction. Anatomic studies showed that helix vascularization depends mainly on the superficial temporal vessels. The presence of vascular communications between the anterior frontal branch of the superficial temporal system and the supraorbital and supratrochlear arterial systems allows this flap to be used in a reverse vascular flow fashion. This new flap has been used successfully in seven cases for reconstructing composite defects of the nasal tip and ala. The donor-site defect is repaired with an advancement and rotation flap from the helical rim, leaving an inconspicuous scar and giving an acceptable cosmetic result of the donor area.
