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）
