Auricular reconstruction is often required for an auricular defect following tumor excision or trauma. It is important for the reconstructed auricle to maintain a complicated three-dimensional structure and to have structural strength against scar contracture. Many reconstruction methods for an auricular defect have ever been reported in the literature. Reconstruction methods using only soft tissues were common in early reports, but these methods cause postoperative deformity due to scar contracture. Therefore, reconstruction methods with a cartilage graft or using a chondrocutaneous flap are now preferred. Reconstruction using local flaps has an advantage over reconstruction using skin grafts because good color and texture match of the reconstructed auricle can be obtained. With elucidation of the hemodynamics of the auricle, various local flaps around the auricle have been developed, and the stability of blood supply of the flaps has improved. In this report, we classify the reconstruction methods and discuss the utility of each method, and we present our strategy for partial reconstruction of the auricle.
