An oronasal fistula is an abnormal opening connecting the oral cavity and the nose. They could occur as complications of oral and maxillofacial procedures. Oronasal fistulas (ONF) are challenging to repair optimally. The repair of a recurrent ONF is more of an enigma in cases where a small defect often requires an extensive surgery to close. Platelet rich fibrin (PRF) was described by Choukroun as a platelet concentrate from autologous blood which forms a single fibrin biomaterial after centrifugation. This haemostatic plug rich in growth factors is easy to prepare, manipulate; and adapt for soft and hard tissue healing. It has been utilized in the various fields of dentistry especially oral and maxillofacial surgery. Reports of role of PRF in the repair of ONF closure are scarce in literature especially in conjunction with other soft tissue flaps. This case report highlights that PRF can be used with success as an adjunct for the closure of ONF fistulas.
