TY - JOUR TI - Effects of topical mitomycin-C on the tracheal epithelia of rabbits following tracheostomy AB - Background/aim: We aimed to investigate the topical application of mitomycin-C (MMC) after the conventional tracheostomy in a rabbit model. Materials and methods: Twenty-four male New Zealand White rabbits were randomly divided among 3 equal groups (n: 8). Tracheostomies were performed on 16 subjects. Group 1 which served as a control for all tracheal measurements. After tracheostomy, we applied sterile saline (group 2) or MMC at 0.8 mg/mL (group 3) around the tracheotomy site for 5 min. At the 3rd week after surgery, all tracheas were subjected to morphometric and histopathological examinations, including tracheal lumen diameter (LD), number of capillary vessels (CV), subepithelial tissue thickness (SETT), fibroblasts, and inflammatory cells (IC). Results: There was a statistically significant difference between the two tracheostomy groups themselves and the control group for LD (p= 0.035), CV (p = 0.006), SETT, fibroblasts, and IC (p < 0.001). Histopathological analysis showed the decreased LD, CV, SETT, IC, and fibroblasts compared to MMC with tracheostomy groups. MMC was more effective than saline for LD, CV, SETT, IC, and fibroblasts. Conclusion: Wound healing modulation may prevent scar formation. Fibrosis decreased following tracheostomy in the group treated with MMC. Fibroblasts appear to be key cells mediating these effects.Key words: Tracheostomy, tracheal epithelia, rabbits, mitomycin-C (MMC) AU - ARIBAS, Olgun Kadir AU - Esme, Hidir AU - Arslan Kasdoagan, Zumrut Ela AU - CALIK, Mustafa AU - Calik, Saniye Goknil AU - AVUNDUK, MUSTAFA CIHAT DO - 10.3906/sag-1802-187 PY - 2021 JO - Turkish Journal of Medical Sciences VL - 51 IS - 2 SN - 1300-0144 SP - 857 EP - 863 DB - TRDizin UR - http://search/yayin/detay/484968 ER -
