Abstract Introduction The ear deformity Tanzer type V, also known as prominent ears, is the most common genetic defect of the pinna. The surgery designed for its correction is known as otoplasty. This esthetic surgery can be performed using different techniques, which requires great skill of its operator. Objective The purpose of this work is the development of a new tool for otoplasty techniques training, aimed on the possibility to minimize errors during the otoplasty. Methods Synthetic molds of the external ear from patients with Tanzer type V deformity were made, using silicone material and rayon. Results The main procedures of otoplasty could be performed in the molds made of silicone and rayon with a good esthetic result. Conclusion The elaborated molds had identical size and shape of a human ear and could be positioned in the same shape of the patient ears. Thus, the synthetic molds were presented as promising simulation tools for the training and surgical enhancement of otoplasty, especially for doctors beginners.
Resumo Introdução A deformidade da orelha tipo V de Tanzer, também conhecida como orelhas proeminentes, é o defeito genético mais comum da aurícula.

Objetivo O objetivo desse trabalho é o desenvolvimento de uma nova ferramenta para o treinamento de técnicas de otoplastia, com o objetivo de minimizar erros durante a otoplastia. Método Foram feitos moldes sintéticos da orelha externa de pacientes com deformidade tipo V de Tanzer com material de silicone e rayon. Resultados Os principais procedimentos de otoplastia foram feitos nos moldes de silicone e rayon com um bom resultado estético. Conclusão Os moldes elaborados tinham tamanho e forma idênticos aos de uma orelha humana e puderam ser posicionados no mesmo formato das orelhas dos pacientes. Assim, os moldes sintéticos foram apresentados como ferramentas de simulação promissoras para o treinamento e aperfeiçoamento cirúrgico da otoplastia, especialmente para médicos iniciantes.
