Microtia deformity correction with three-dimensional and two-dimensional templates: A pathway for effective ear reconstruction

Abstract

Expression of anatomical landmarks of the ear results in the success of ear reconstruction in microtia. Ear reconstruction in India is routinely done with a two-dimensional (2D) template by tracing the contralateral ear with an X-ray sheet. There is a need of a proper template to understand the finer details of the ear reconstruction. In this report, a three-dimensional (3D) template in association with a 2D template is utilised to augment the reconstruction ability of the plastic surgeon. After computed tomography scan, an accurate 3D scan of the normal ear is obtained. Using the 3D ear model file, a negative mould of the ear 3D model is developed and fed into a 3D printer. The model is sterilised and used for reconstruction. Hyperbaric oxygen therapy is used as an adjunct for the procedure. Simultaneous utilisation of 3D and 2D templates for ear reconstruction appears to increase the ability of plastic surgeons to recreate the ear.
