Question:
How common are problems with implants used in rhinoplasty? How often does extrusion or implant shifting occur?
Answer:
The answer to your question varies with the type of implant used. Some implants are porous and others are solid. According to current literature, infection occurs in 2-3% of patients with porous high-density polyethylene (PHDPE) and expanded polytetrafluoroethylene (e-PTFE or Goretex) nasal implants. Extrusion of the implant is less likely after adequate tissue ingrowth into a porous implant, but it is more likely to occur in solid rigid implants. Overall, extrusion seems to occur in anywhere from 1 to 5% of patients. Shifting of the implant is also more likely in solid implants since they do not allow for tissue ingrowth.
