Microtia reconstruction: an update

Abstract

Reconstruction of the microtic ear remains one of the most challenging procedures encountered by the reconstructive surgeon. The use of autogenous rib cartilage continues to be the gold standard for microtia repair. Numerous refinements and modifications in the original technique described by Tanzer have paved the way for exceptional results in experienced hands. However, ideal results are not always achieved, and there continue to be drawbacks with the standard approach to reconstruction with autogenous rib cartilage. In an attempt to circumvent these shortcomings, surgeons have developed alternative or adjuvant techniques to repair the microtic ear, including the use of tissue expansion, alloplastic implants, and osseointegrated prostheses. Finally, greater emphasis is being placed on early atresia repair in appropriate candidates.
