Use of rapid prototyping in prosthetic auricular restoration.

Reconstructing auricular defects is a challenging task for facial reconstructive surgeons. Although autologous reconstruction is the first choice for reconstruction, there may be circumstances of inconvenience such as previously attempted surgery, radiotherapy, systemic conditions, or patient's wish. Auricular restorations with facial prosthesis have produced promising results, but there are still problems to be tackled for improved results.
