title: Dual-porosity expanded polytetrafluoroethylene implants for lip, nasolabial groove, and melolabial groove augmentation.
abstract: OBJECTIVE
  To evaluate the clinical outcomes with the use of a dual-porosity expanded polytetrafluoroethylene implant for midfacial rejuvenation.
  
  
  METHODS
  An institutional review board-approved retrospective chart review was conducted of all patients who underwent implantation with the dual-porosity expanded polytetrafluoroethylene implant between 2001 and 2005.
  
  
  RESULTS
  A total of 170 patients, with 612 implants, were evaluated. Only 8 patients had minor complications, 3 of which necessitated implant removal. The overall results of independent observer analysis of outcomes were favorable in the majority of cases.
  
  
  CONCLUSIONS
  The dual-porosity expanded polytetrafluoroethylene implant is safe and reliable to use for midfacial implantation.
