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.
Conclusion:
Porous polyethylene is stable as a nasal dorsal implant in Asians. Explantation can also be performed with ease if needed.
