Correction of microtia with construction of the tragus using a chondrocutaneous flap.
For microtia correction we have been inserting a cartilage framework and reconstructing the tragus at the first operation in one stage, using part of the microtic ear. This procedure is started with transposition of the lower two-thirds of the microtic ear to make a lobule. The upper third of the microtic ear is elevated as a chondrocutaneous flap which is then transposed downwards to the conchal cavity to make a tragus. The cartilage of the chondrocutaneous flap is anchored, using a bolster to pull it back and outwards. Using this technique, we have reconstructed 34 microtic ears. Adequate positioning of the auricle and tragus has been achieved and a natural auricle obtained even when observed from a frontal oblique direction.
