A new method for training of ear framework creation by silicon dental impression material.

This article presents the novel method of training of creating cartilage framework for total ear reconstruction in microtia. Replica of costal cartilage harvested for real surgery was simulated by silicon dental impression material. Carving of framework was done with wood carving instruments. Silicon dental impression material gives the consistency and texture almost comparable to real costal cartilage. Sequential steps similar to actual surgery were simulated to create the three-dimensional framework.By using this novel technique, novice surgeons can practice creating ear framework and improvise their results in the actual surgery.
