ABSTRACT

--------------------------------------------------------------------------------
Background and Objectives:A lot 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(r), and Alloderm(r)), 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(r), which was a little difficulty to remove, had good volume preservation with focal ing-rowth of fibroblasts and inflammatory cells. A gross examination of Alloderm(r) showed preserved volume, but thin, soft and weak appearance. A microscopic examination of Alloderm(r) 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(r) is a good volume filler for dorsal augmentation, whereas Alloderm(r) is a good material for camouflage. (Korean J Otolaryngol 2001;44:163-7)
