Özet

This study evaluates the soft tissue response in rabbits following laryngeal implantation for medialization using Gore-Tex (expanded polytetra-fluoroethylene) and silicone (dimethylpolysiloxane) rubber. Histopathologic findings were evaluated according to six parameters: Fibrous capsule formation, histiocyte, foreign body giant cell, eosinophil, neutrophil and lymphoplasmacyte infiltration. Each parameter was graded into five groups: Negative (0), mild (1), mild-moderate (2), moderate (3), moderate-severe (4), severe (5). In animals implanted with silicone rubber, median grades for parameters were: Fibrous capsule formation (4), histiocyte (0), foreign body giant cell (0), eosinophil (1), neutrophil (0) and lymphoplasmacyte (1) infiltration. In animals implanted with Core-Tex, median grades for parameters were: Fibrous capsule formation (2), histiocyte (1), foreign body giant cell (I), eosinophil (0), neutrophil (0) and lymphoplasmacyte (1) infiltration.
