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 and methods : 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.
