Histopathological effects of fibrin glue in maxillary sinus mucosa: An experimental study

33058

Aim. Fibrin glue is used as a tissue adhesive and local haemostatic agent during intranasal surgeries and it also causes mechanical fastening of tissue repairing procedure. Fibrin glue is generally considered highly biocompatible and adhesive to tissue surfaces, but it has very low cohesive strength. The aim of this study was to assess the histopathological effects of fibrin glue in maxillary sinus mucosa in the animal model. Method. Ten Wistar albino rats were used. The fibrin glue used for the present study was a fibrinogen-based compound with double sealant components. Ten rats were anaesthetized with ketamine HCl, then the fibrin glue was applied in the left maxillary sinus, and sterile saline solution was injected in the right maxillary sinus. On postoperative day 21, the animals were euthanatized and maxillary sinus mucosa was resected for histopathological examination. Fibroblast proliferation, vascular proliferation, fibrosis, and inflammatory cell infiltration were scored from zero to three and the ratios of edema and necrosis were reported. Results. There were no significant differences in fibroblast proliferation, vascular proliferation, fibrosis, and inflammatory cell infiltration scores and the ratios of edema and necrosis between the saline and fibrin glue groups. Conclusions. Our findings support the use of fibrin glue for sinus surgery. But the surgeon should be aware of the fact that it has a potential to cause inflammatory changes.
