PURPOSE OF REVIEW: Creating the fine details of the ear in a patient with a congenital absent ear is extremely challenging. Each component of the multidisciplinary team that manages the ear reconstruction, hearing restoration, and associated craniofacial anomalies of these patients has seen recent progress. RECENT FINDINGS: Population studies have provided new insights into the etiology of microtia. Novel techniques for costal cartilage harvest, implantation, and positioning add to the techniques of Brent and Nagata, which remain the gold standard for microtia repair. Advances in the use of alloplasts and tissue-engineered cartilage appear promising. SUMMARY: Technical advances in combined aural atresia/microtia reconstruction, bone-anchored prosthetics, bone-anchored hearing aides, and use of alloplastic implants provide numerous options to patients and practitioners. Implantable, tissue-engineered auricular frameworks appear to be a promising option for the future.
