Abstract
Introduction: Palatal fistula is a relatively common complication of surgical procedures to treat congenital or acquired conditions on the hard or soft palate. Its treatment is associated with high recurrence rates. Blood extracts passed by centrifugation are being commonly used for the stimulation of palatal cells for tissue regeneration, promoting faster healing. Case Report: This case report is to describe the case in which platelet-rich fibrin (PRF) membranes were used to close the palatal fistula after flap necrosis. Conclusion: Among the usual blood extracts, PRF has been shown to be effective for adjuvant treatment of palatal fistula healing.
