Abstract
The purpose of this study was to construct an auricular shape database for making a prototype of an auricular prosthesis by using rapid prototyping technology. We extracted the auricular data from 3D-CT data at Hokkaido University Hospital in the past. Extracted data were interpolated and saved into the database in voxel format and STL format. 3D-CT data of 145 cases were surveyed and 70 cases, involving 130 auricular data, were selected. In addition, we tried to make a surgical template for auricular reconstruction at the request of a plastic surgeon, to be used for adjusting the cartilage of rib to the auricular shape. We used the shape data of the auricular database to make it and examined the problems.
