BACKGROUND: The aim of this study was to compare the compatibility of Alloderm, Dacron, Gore-Tex, and autologous cartilage graft materials with host tissues in nasal septal perforation repair surgery. METHODS: The materials were placed into the nasal septum of 16 New Zealand rabbits. At the end of the 3rd month, septums of the rabbits were removed totally and reactions, such as inflammation;foreign body giant cell; or fibrosis that developed in the surrounding tissue against the implant material were evaluated. RESULTS: Acute inflammation reactions occurred mostly with Gore-Tex. There were no differences between groups according to chronic inflammation. When the number of reactions and tissue compatibility were taken into consideration, cartilage performed the best followed by Alloderm. There were more reactions with Dacron, but it still showed compatibility. CONCLUSION: Cartilage was found to be the best material followed by Alloderm and Dacron, but Gore-Tex was found unsuitable.
