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 In this technique, 10 ml of blood is withdrawn from the patient, processed in a centrifuge machine, and platelet-rich fibrin (PRF) is separated from the mixture for use in the repair of small tympanic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.
评估富自体血浆纤维蛋白栓技术修复小鼓膜穿孔的有效性。富血小板纤维蛋白(PRF)因其含有大量可用于鼓膜穿孔闭合的生长因子,也被称为第二代富血小板血浆。由于其为自体来源,易于获取且无免疫原性反应。PRF膜具有包含生长因子的强大弹性蛋白纤维结构,因此可被视为修复鼓膜穿孔的理想密封材料或移植物的辅助材料。我们进行的是一项前瞻性研究。共有52例干性小鼓膜穿孔患者纳入本研究。在该技术中,从患者体内抽取10毫升血液,在离心机中进行处理,从混合物中分离出富血小板纤维蛋白(PRF)用于修复小鼓膜缺损。52例患者中,42例鼓膜成功修复(完全闭合)。穿孔闭合的平均时间约为2周。然而,其中5例修复失败。尽管穿孔大小较术前有所减小。此外,2例患者鼓膜上出现肉芽组织。未观察到严重副作用。自体PRF是通过离心过程从全血中获得的产物。它通过将高浓度的血小板衍生生长因子以及纤维蛋白融入移植物混合物中,在促进伤口愈合的自然过程方面安全有效。这有助于鼓膜穿孔的快速愈合。
