title: Clinical outcomes following ear reconstruction with adjuvant 3D template model.
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.
  
  
  OBJECTIVE
  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 a 3D 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).
