Abstract

New method to exercise creation of three-dimensional cartilage framework for ear by using a precise copy of the costal cartilage is presented. Precise negative impressions were taken from harvested 6th to 9th rib cartilage using molding material. Silicon-type dental impression material was injected into the negative impression to create a copy of the costal cartilage. Simulated surgical procedures were performed to evaluate this model; each step of creating three-dimensional framework for total auricular reconstruction was performed with exactly the same instrumentation for real surgery. We found that simulation of surgery was successfully performed, and created three-dimensional framework was very close to the real costal cartilage framework.By using a precise copy of the costal cartilage, simulation of creating ear framework came to a very realistic method to practice, and this method may give the "ear maker" a good opportunity to prepare for the actual surgical procedure.
