Three-Dimensional Printing as a Potentially Effective Strategy for Improving the Outcomes in Microtia Reconstruction

Abstract

Aim: The reconstruction of microtia cases is a challenging topic and auricular reconstruction is a unique area of facial plastic surgery where a wide array of reconstructive options often must be considered. The goal is to assess the use of three-dimensional (3D) printing to create a 3D model for use during reconstruction to achieve better aesthetic results.Patients and Methods: This study included ten patients with microtia. Utilizing two stages of ear reconstruction, the authors used a 3D printed auricular model of the contralateral ear as an intraoperative guide. The Mansoura ear reconstruction scale was conceptualized and used by the authors to assess the final aesthetic outcomes.Results: In total there were 10 patients with 11 affected auricles. Results were 6 patients with an excellent result, 3 patients with a very good result and one patient with a fair result according to Mansoura ear reconstruction scale. Conclusions:The use of 3D printed models for microtia reconstruction resulted in an overall increase in aesthetic outcomes and increased patient satisfaction.
