Abstract

|
Background: Gore-Tex implants started out as a product with the distinct advantage of producing a natural nose shape, but using Gore-Tex, it is difficult to predict the height of the nose after rhinoplasty because Gore-Tex contracts over time, making the nose shrink. However, Surgiform, a new form of expanded polytetrafluoroethylene (ePTFE) implant, enables prediction of the height of the nose after rhinoplasty because the implant does not change in thickness even after many years. Thus, we investigated whether changes in implant thickness occurred after rhinoplasty using Surgiform implants.
Methods: This study enrolled 12 patients who had Surgiform nasal implants removed for any reason after receiving rhinoplasty in 2007 or later. After the Surgiform implants were removed, we measured the thickness of the central part of the implants using calipers.
Results: At the time of the initial operation, the mean implant thickness was 4.48±0.30 mm at the supra-tip. At the time of implant removal, the mean thickness was 4.32±0.29 mm. The implants maintained 96.5% of their initial thickness. There was a negligible reduction in the Surgiform implants' thickness over time.
Conclusions: Surgiform implants maintained their shape after rhinoplasty, making it possible to predict the height of the nose. Thus, Surgiform is more useful for nasal implants than other ePTFE implants.
