title: Use of porous polyethylene as nasal dorsal implants in Asians.
abstract: BACKGROUND
  A variety of implants have been used for nasal augmentation. A new implant made of porous polyethylene has recently been available.
  
  
  OBJECTIVE
  To evaluate the stability (non-extrusion) of MEDPOR porous polyethylene as nasal dorsal implants in Asian patients.
  
  
  METHODS
  Nineteen patients' charts were reviewed looking for implant displacement, extrusion of porous implants, postoperative bleeding and infection of tissues surrounding the implants in the postoperative follow-ups which range from 3 months to 5 years.
  
  
  RESULTS
  No postoperative bleeding, infection, or displacement or extrusion of porous implants was noted. Explantation was easily performed in one patient.
  
  
  CONCLUSIONS
  Porous polyethylene is stable as a nasal dorsal implant in Asians. Explantation can also be performed with ease if needed.
