title: Nasal prosthesis rehabilitation using CAD-CAM technology after total rhinectomy: a pilot study.
abstract: OBJECTIVE
  This study describes a nose prosthetic rehabilitation using computer-aided design and manufacturing (CAD-CAM) technology after facial disfigurement because of a total rhinectomy.
  
  
  METHODS
  A patient with a total rhinectomy was scheduled for a nasal prosthesis. Based on the 3-D model of the patient's face reconstructed with the CT data, a four-piece mould for the nasal prosthesis was prototyped using a CAD-CAM procedure. Conventional silicone was processed with this physical mould to fabricate the definitive nasal prosthesis.
  
  
  RESULTS
  A silicone nasal prosthesis was manufactured. The size, shape, and cosmetic look of the prosthesis were satisfactory and matched the nasal defect area well.
  
  
  CONCLUSIONS
  The protocol presented herein illustrates favorable clinical treatment outcomes in the prosthetic rehabilitation after a total rhinectomy by means of CAD-CAM technology.
