Reconstruction of auricular conchal defects with local flaps

View Article: PubMed Central - PubMed

ABSTRACT

Reconstruction of the auricular conchal cavity is relatively difficult because of its unique structure, shape, and location. We compared different methods of repair of the auricular concha to determine the method that would cause the least injury to the donor site.

The method selected was based on the location and size of the defect. If the defect was located in the upper part of the concha, or if the defect was >15 mm in diameter, we used a post-auricular subcutaneous pedicle island flap that was pulled through a post-auricular sulcus tunnel to cover the wound. If the defect was located in the lower part of the concha and was <15 mm in diameter, we used a pre-auricular translocation flap that was passed through the intertragic notch to cover the wound. The donor site was closed primarily. All flaps survived well and any scars associated with the surgery were unnoticeable. No tumor relapse or metastasis was observed over a mean follow-up period of 35 months. All patients were satisfied with the outcome.

The periauricular flap technique chosen for reconstruction of skin defects in the auricular concha depends on the size and location of the defect. With appropriate flap selection, excellent functional, and aesthetic outcomes are achieved.

Mentions: Defects that were located in the lower part of the concha and were < 15 mm in diameter, were repaired using a preauricular translocation flap (PAT). A translocation flap was created in front of the tragus, with the pedicle situated inferiorly and the distal end of the flap situated superiorly. The skin of the intertragic notch, between the defect and the flap, was excised. The flap was rotated through the intertragic notch in order to cover the defect (Fig. 2). The skin of the donor site was closed with a primary closure technique through mobilization of the surrounding tissue. The sutures were removed after 1 week.
