Abstract：Objective To report application of three-dimensional printing technology in individualized auricle re-construction. Methods High resolution computed tomography(HRCT) images of the temporal bone in unilateral micro-tia patient were scanned.Auricle and its surrounding structure of auricle on the healthy side was mirrored,then the auri-cle on the affected side was reconstructed by using mimics software.3-D earmould was designed by using 3-matic soft-ware and then silicone mirrored ear auricle model and 3-D silicone earmould was manufactured by the technology of fused deposition molding(FDM)and silicone impression, the former was used as reconstructed auricular templates,the latter was used as guide plate respectively on the affected side to increase the precision in fabrication of cymba conchae, the cavum conchae,triangular fossa,the helix,antihelix and other substructure of auricle and maintainance of cranioauric-ular angle. We made a comparison about the preoperative appearance and the postoperative appearance in size and shape and substructure of auricle.Results The appearance of the postoperative auricle is realistic.Cranioauricular angle is symmetrical, and the anatomical substructure of auricle is clear. Conclusions The application of 3-d printing technolo-gy can fine individual auricle reconstruction,and it provides a novel method for auricle reconstruction.
