Abstract
CONCLUSIONS: The use of the 3D template model in microtia surgery leads to satisfactory results, for its contribution to the engraving and localization of the microtia auricle in auricle reconstruction. OBJECTIVES: The aim of the study was to create an anatomical correct 3D rapid prototyping model for patients with microtia, to assist with the accurate fabrication and localization of a coastal cartilage framework for auricular reconstruction, and patients, who had undergone rib-cartilage reconstruction to treat a congenital auricular defect, were evaluated for aesthetic outcomes following ear reconstruction with a different template model. METHODS:Forty patients with unilateral congenital microtia were enrolled in this study during the last 2 years, they were divided into two groups randomly before surgery; 20 patients who had a3D digital template made for clinical application and the other 20 who underwent ear reconstruction with a 2D template. RESULTS: The patients who had undergone ear reconstruction with the 3D template model had a better result of the appearance and location of the constructed auricle, and a higher level of satisfaction with their clinical outcomes (p < .05).
