One-stage reconstruction of two atypical small concha-type microtic ears

Abstract This report presents 2 cases of atypical small concha-type microtia, which were reconstructed with full utilization of the remnant cartilage. To repair the deformity, we harvested the 8th and 9th costal cartilage to form the helix and anthelix structure. The remnant auricular cartilage mass was retained and utilized as the base block of the framework, onto which sculptured helical rim and anthelix were added. Thus an ear of symmetrical shape, projection and visible convolutions was reconstructed. We suggest making use of the remnant cartilage to minimize the donor site morbidity, especially for mild to moderate microtia reconstruction.
