Description
Summary:Aims: To assist with the accurate fabrication and localization of a costal cartilage framework for auricular reconstruction, three-dimensional (3D) digital and solid templates including the auricle and guide plate were made for microtia patients. Methods: The computed tomography data of 60 patients with microtia were included. The 3D digital template of the auricle and guide plate on the healthy side was shaped using MIMICS software with graphic image processing and 3D reconstruction technology. The 3D digital template on the affected side was produced by mirror technique and made into a solid template for clinical application. Results: All 60 patients had a good result of the location and the appearance of the constructed auricle. The time of operation was decreased by an average of half an hour. An individualized 3D solid model of the reconstructed auricular template on the affected side was successfully produced and used in auricular reconstruction. Conclusions: The new 3D template of the auricle and guide plate may be a major contribution to the engraving, assembling and localization of the microtia auricle in auricular reconstruction.
