Reconstruction of nonmarginal defects of the ear with chondrocutaneous advancement flaps.

Marginal defects of the ear are usually reconstructed with the Antia's chondrocutaneous flap. Reports of reconstruction of nonmarginal defects are scanty. The antia chondrocutaneous flap was adapted for reconstruction of defects up to 2 cm located in the triangular fossa, scapha, and the anthelix. For larger defects, the technique was further modified using composite chondrocutaneous flaps. The technique uses the principle of separation of the ear elements and redistribution for closure of defects in the nonmarginal areas of the ear with minimal sacrifice of the tissue, ear size, and ear shape. This technique is reliable, relatively simple, and a one-stage operation, as demonstrated in our series of seven patients.
