Platelet-Rich Fibrin impact on the Diced Cartilage viability in Rhinoplasty

Introduction: Diced cartilage grafts are well-liked, dependable, and simple-to-use techniques for dorsum camouflage in rhinoplasty. Recent research results demonstrate how effectively PRF increases the survivability of diced cartilage in the nasal dorsum and decreases its absorption. In this study, we intend to investigate the effect of fibrin-rich platelets (PRF) on diced cartilage survival in rhinoplasty surgery.Materials and Methods: This clinical trial included people referred to Rasoul Akram Hospital for rhinoplasty between ۲۰۲۰ and ۲۰۲۱. Patients were divided into two groups: Diced Cartilage alone (DC) and Diced Cartilage + PRF (DC+PRF). Cartilage survival was assessed by ultrasound, photography, and nasal examination, and the two groups were compared six months after rhinoplasty. Patients' satisfaction with surgery was also evaluated using the Utrecht questionnaire.Results: The mean age of the two groups of ۲۰ patients was ۲۹.۰۵ ± ۷.۰۲ and ۲۶.۶۵ ± ۸.۱۶ years in the DC and DC + PRF groups, respectively (P>۰.۰۵). After treatment, the frequency of irregularity on examination and dissatisfaction score was slightly but insignificantly higher in the DC group compared to the DC + PRF group (۲۵% vs. ۱۵% and ۱۲.۲۵ ± ۶.۴۵ vs. ۱۰.۴۵ ± ۶.۷۴, respectively, and P values>۰.۰۵). The total volume decrease, regardless of the injection site, was significant in both groups (P < ۰.۰۵), but the magnitude of volume reduction was significantly higher in the DC group compared to the DC + PRF group (-۰.۰۶۰ ± ۰.۰۸۷ vs. - ۰.۰۳۳±۰.۰۱۷, respectively, P<۰.۰۵).Conclusion: PRF may slow down the absorption process of diced cartilage.
