title: Multicenter evaluation of subcutaneous augmentation material implants.
abstract: OBJECTIVE
  To evaluate the performance of subcutaneous augmentation material preformed shapes for facial implantation.
  
  
  METHODS
  One-year prospective multicenter evaluation of implant performance.
  
  
  METHODS
  General community hospital; private and institutional practice; and ambulatory care setting.
  
  
  METHODS
  Eighty-two patients undergoing elective cosmetic and reconstructive procedures.
  
  
  METHODS
  Patients received nasal dorsal implants (31 patients); chin implants (38 patients); and malar implants (13 patients).
  
  
  METHODS
  Complications and aesthetic outcome, including implant position, projection, contour, symmetry, and overall aesthetic index.
  
  
  RESULTS
  Complication rates for infection that required implant removal included nasal dorsal implants, 3.2%; chin implants, 5.3%; and malar implants, 3.8%. The overall aesthetic outcome was judged by an independent panel of facial plastic surgeons on a scale from 1 (poor) to 5 (excellent): nasal dorsal implants scored 4.1; chin implants, 3.8; and malar implants, 3.6.
  
  
  CONCLUSIONS
  This study demonstrates that subcutaneous augmentation material preformed shapes offer a relatively safe and effective treatment alternative for permanent facial augmentation.
