Effects of Platelet-Rich Fibrin on Postoperative Outcomes Following Nasosinusal Surgery

Sponsor: Hospital Edmundo Vasconcelos

View on ClinicalTrials.gov

Summary

tudy Design This was a prospective, randomized, double-blind, controlled clinical trial designed to evaluate the effects of platelet-rich fibrin (PRF) on postoperative healing following partial inferior turbinectomy. Patients undergoing surgery at the Centro de Otorrinolaringologia e Fonoaudiologia de São Paulo (COF) were allocated to either a PRF treatment group or a control group. Postoperative outcomes were assessed at 1 week and 1 month after surgery using a standardized evaluation protocol completed by blinded investigators. Clinical parameters related to wound healing and postoperative recovery were recorded and subsequently compared between groups to determine the impact of PRF application on surgical outcomes.

Interventions

PROCEDURE

Platelet-rich fibrin (PRF)

Autologous platelet-rich fibrin (PRF) prepared intraoperatively from the participant's peripheral blood through a single-step centrifugation process. The resulting fibrin membrane was applied topically to one randomly selected nasal cavity at the completion of partial inferior turbinectomy, while the contralateral nasal cavity served as an untreated control. PRF contains a dense fibrin matrix enriched with platelets, leukocytes, cytokines, and growth factors that may promote mucosal healing and reduce postoperative crust formation. Postoperative outcomes were assessed at 1 week and 1 month after surgery by blinded evaluators.

PROCEDURE

Control

No intervention done in one side of the nasal cavity
