The Impact of Topical Application of Platelet-Rich Fibrin on Graft Survival in Surgeries for Chronic Otitis Media

Objective: This study aims to evaluate the efficacy of platelet -rich fibrin (PRF) application in tympanoplasty procedures for patients with chronic otitis media (COM), assessing its influence on graft survival and healing time. Methods: In this prospective interventional study, conducted between January 2022 and June 2023, 80 patients diagnosed with COM were enrolled and divided into two groups. Group A underwent standard tympanic membrane repair using temporal fascia grafts (TFG), while Group B received TFG with adjunctive PRF application. The patients were observed and assessed over a 20 -week postoperative period. Results: The study showed a significant enhancement in graft survival rates in Group B (TFG+PRF), with only one residual perforation compared to seven in Group A (TFG alone) at 20 weeks (p=0.02534). Furthermore, Group B patients experienced faster healing, achieving 97.5% graft integrity at 10 and 20 weeks, in contrast to Group A's 87.5%. Conclusion: The application of PRF in tympanoplasty procedures for COM notably enhances graft stability and expedites the healing process. These findings suggest that PRF can be a valuable adjunct in otolaryngological surgeries, offering potential improvements in patient outcomes and surgical efficacy.
