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 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.
