ABSTRACT
BACKGROUND AND OBJECTIVES:
An array of materials have been used for rhinoplasty, however, the fate of these materials after rhinoplasty is not all clear. This study was performed to find post-operative gross and microscopic changes of the implants and grafts (cartilage, Gore-Tex , and Alloderm), and to guide selection of implants and graft. MATERIALS ANDMETHODS:
We took the implants and grafts out from nine patients who underwent revision rhinoplasty for cosmetic problems, and studied gross and microscopic charaterizations.RESULTS:
Autologous cartilages showed minor volume reduction and remodeling in gross examination, and mild degeneration, peripheral fibrosis, and fibroblast in-growth without inflammation under microscopic examination. Gore-Tex , which was a little difficulty to remove, had good volume preservation with focal in-growth of fibroblasts and inflammatory cells. A gross examination of Alloderm showed preserved volume, but thin, soft and weak appearance. A microscopic examination of Alloderm showed well preserved collagen materials without inflammation.CONCLUSIONS:
Cartilages have good biocompatibility and stabilization, but it is necessary to study absorption and remodeling. We found that Gore-Tex is a good volume filler for dorsal augmentation, whereas Alloderm is a good material for camouflage.
