Advancement in Tympanic Membrane Repair: Exploring the Potential of Platelet Rich Fibrin

To assess the effectiveness of the autologous plasma-rich fibrin plug technique for repairing small tympanic membrane perforations. Platelet rich fibrin (PRF) is also called second generation platelet rich plasma due to its high amount of growth factors which could be used in tympanic perforation closure. Being autologous, it is readily available with no immunogenic reactions. PRF membrane has a strong elastin fibrin structure containing growth factors and hence can be considered as an ideal sealing material or an adjuvant to the graft in repairing tympanic membrane perforations. Ours is a prospective study. A total of 52 patients with dry small tympanic membrane perforation were included in the study. In this technique, 10 ml of blood is withdrawn from the patient, processed in a centrifuge machine, and platelet-rich fibrin (PRF) is separated from the mixture for use in the repair of small tympanic membrane defects. Out of the 52 patients, 42 experienced successful repair (full closure) of the tympanic membrane. The mean time of closure of the perforation was around 2 weeks. However, five of them encountered failure. Although the size of the perforation decreased compared to the preoperative size. Additionally, two patients developed granulations on the tympanic membrane. No major side effects were noted. Autologous PRF is a product derived from whole blood through the process of centrifugation. It is safe and effective in promoting the natural process of wound healing by incorporating a high concentration of platelet-derived growth factors as well as fibrin into the graft mixture. This facilitates the rapid healing of tympanic membrane perforation.
