Abstract
IntroductionThe 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. ObjectiveThe 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. MethodsSynthetic molds of the external ear from patients with Tanzer type V deformity were made, using silicone material and rayon. ResultsThe main procedures of otoplasty could be performed in the molds made of silicone and rayon with a good esthetic result. ConclusionThe 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.
Highlights
The ear deformity Tanzer type V, known as prominent ears or ‘‘floppy’’, is the most common genetic defect of the pinna
This paper proposes the creation of external ear molds made with silicone, for the otoplasty techniques application, in order to be used as a viable tool in the training and surgical skills improvement of doctors’ beginners
There are, many surgical techniques used in this procedure, highlighting the technique developed by Mustardé, Stenstrom and Furnas (1968)16---18 in which the ear cartilage is sutured, transfixing it to the previous perichondrium, in the mastoid fascia, with unabsorbed thread
Summary
The ear deformity Tanzer type V, known as prominent ears or ‘‘floppy’’, is the most common genetic defect of the pinna. It is mainly caused by the anti-helix blemish, sharp protrusion and shell development, or a mixture of both.[1]. Dieffenbach was among the first when, in 1845, he described his technique of otoplasty to correct a posttraumatic prominent auricle in a patient.[2]. There are studies using animal models to employ surgical techniques of otoplasty, there is still no description of synthetic models for this purpose. The number of animals used for training purposes decreases and it is developed the students’ confidence to work with alive tissues.[3]
