Background: Ear reconstruction is the necessary choice for patients with congenital lobule microtia. The best results are still obtained by autogenous cartilage ear reconstruction. We developed a three-dimensional autogenous costal cartilage framework for auricular reconstruction with the purpose of achieving a new auricle of high fidelity. Methods: The patient's sixth to eighth rib cartilages were harvested as auricular framework materials, which were divided into three laminates for carving fine anatomic structures. By connecting and fixing, a three-dimensional auricular framework with a concha, helix, antihelix, triangular fosse, and navicular fossa could be used for the auricular reconstruction. Results: The results obtained were considered satisfactory with vivid individual appearances and neat stable structures. Six frameworks were exposed or modified due to hematoma, infection, or cutaneous necrosis. Conclusions: With a three-dimensional auricular framework, the minute anatomic structures cited above make the external ear silhouette more vivid.
