Platelet Rich Fibrin Graft in Myringoplasty: Pitfalls and Challenges

AbstractAutologous Platelet-rich fibrin (PRF) is an amalgam of fibrin mesh, platelets and growth factors that favour wound healing. It can be easily used as a graft material in myringoplasty, making it a promising, easy to harvest and cost effective alternative compared to cartilage or fascia graft used in conventional myringoplasty. 50 patients of small to medium, dry central perforation underwent myringoplasty using PRF graft (Group 1). Results were compared to 50 patients with similar small to medium perforations who underwent conventional transcanal myringoplasty using temporalis fascia graft (Group 2): Outcome of surgery was measured by closure of perforation and improvement in hearing at 3 months. In group 1, overall closure rate was 70% while in group 2 it was 96%. For both small and medium perforations healing was significantly higher in group 2 compared to group 1, (100% vs 87.5%) for small perforations and (95.45% vs 66.67%) for medium perforations. Hearing gain was comparable in both groups in patients in whom healing of perforation occurred. PRF stands as a suitable graft material for closure of small perforations, but, lack of rigidity and early disintegration of the graft makes it less suitable for larger perforations compared to other conventional grafts such as temporalis fascia.
