| Research Abstract |
The purpose of this study is the construction of three dimensional auricular shape database.
(1) Extraction, collection, and analysis of auricular shape data
It was possible to collect about 130 pieces of auricular shape data extracting from volume data of 3-D CT.
(2) Construction of 3-D shape database
Three dimensional shape database that was required to make auricular prosthesis was constructed. Auricle model in the database contained the internal structural data that was based on the voxel model.
(3) Examination of materials and making of prosthesis for trial purposes
Auricular prosthesis was made for patient using shape data base. We used the rapid prototyping technology to make the auricular model instead of wax up. In addition, with the proposal of the plastic surgeon, the template for the auricle reconstruction operation was made. As the materials, we examined the silicone and the polyurethane.
(4) Examination of problem for practical use
It was thought that the development of CAD software to practical use was necessary. It will need to be able to operate the shape of the data base easily. It will need to be able to synthesize the shape of auricle data to the patient's photograph of face. And it will need to be able to confirm the result of simulation easily.
