Grouped into 7 subjects in each group. Circular perforation behind thenasal columella about 5 mm posterior and 5 mm in diameter was created on the nasal septum mucosa in each experiment.Curcumin was applied to the study group and control group was also given saline. Intranasal administration was performed astopical agent once daily for 10 days. At the end of the 10th day, a 10x10 mm through-cut nasal septum excision was made toinclude the perforated area. Histopathological examination of specimens were compared taking into account such parameters asepithelial regeneration and degeneration in groups, fibroblast and collagen presence, capillary vessel density, acute and chronicinflammatory cell presence, eosinophils amount, the amount of granulation tissue, giant cell presence, cartilage degeneration andregeneration, the macroscopic closure rate of the perforation.Results: there was a statistically significant difference between groups according to epithelial and cartilage regeneration and theamount of collagen and granulation tissue. It was significantly higher in the curcumin group than in the control group. (p<0,05).No statistically significant difference was found in comparison of other parameters. (p>0.05).Conclusion: Our findings support that curcumin has an accelerating effect on wound healing in the nasal septal mucosa. For thisreason, we may think that curcumin may be beneficial in preventing the development of septal perforation.Key words: Curcumin, nasal septal perforation, nasal septum, experimental study, wound healing, topical.
