One-stage reconstruction of microtia in microform.

We treated five patients with auricular deformities (microtia in microform and group IIB or III constricted ears) using the following procedure: nearly all of the contralateral conchal cartilage was resected, grafted, and sutured to supplement a cartilaginous deficit and to keep the supporting frame of conchal cartilage expanded by the double banner flap method. After this, a soft tissue deficit was reconstructed by our newly developed method of covering the defect with a triangular flap superior to the auricle by making a skin incision and a rhomboid flap anterior to the auricle. So far, we have obtained satisfactory results using this one-stage procedure.
