Abstract:
Tanzer reported microtia reconstruction using autogenous costal cartilage, thereafter so many plastic surgeons have tried various modification to get further refinement of reconstructed auricle. But the multiple stages of ear reconstruction required prolonged hospitalization and cost. In order to decrease the number of surgical stages and for the maximal convolution, we have employed a surgical procedure with three layered costal cartilage graft for the high profile auricle, concha formation and lobule transposition at the same time. However, it has still been difficult to reconstruct the tragus in cases of microtia that lack such component. We reconstructed the tragus using part of the microtic ear in addition to our above procedure simultaneously. This procedure is started with transposition of the lower two-thirds of the microtic ear to make lobule and then the upper third of the microtic ear is elevated as a chondrocutanenous flap which is then transposed 120-180degree C downwards to reposition at the area anterior to the conchal cavity. Using this technique, we have reconstructed 28 microtic ears. Adequate positioning of the auricle and tragus have been achieved and a more natural auricle obtained.
