Platelet-Rich Fibrin Enhances Surgical Wound Healing in Total Laryngectomy.

Abstract

Autologous growth factor (AGF) is a cytokine that has gained medical research interest because it helps improve and accelerate the wound healing process. Platelet-rich fibrin (PRF) is the latest generation of platelet concentrate that can be obtained through a simple procedure known as AGF referencing. One of the most common complications of total laryngectomy (TL) is pharyngocutaneous fistula. To prevent this complication, health care providers must closely monitor the postoperative wound healing process.This study aimed to investigate the effectiveness of PRF application in enhancing wound healing after TL. A randomized controlled trial was conducted in the Department of Otorhinolaryngology - Head and Neck Surgery, Faculty of Medicine, Dr. Cipto Mangunkusumo Hospital Universitas Indonesia, Jakarta, Indonesia, from June 2019 to December 2019. We included 20 patients who underwent TL for laryngeal squamous cell carcinoma. They were divided into two groups (10 patients who received applied autologous PRF around the esophageal stoma during TL and another 10 patients as the control). These patients were observed for 2 weeks postoperatively. In the bivariate analysis performed using the chi-square test, the pain threshold and edema of postoperative wounds in the PRF-treated group demonstrated significant differences compared with those in the control group. PRF application in TL enhanced the postoperative wound healing process, especially with regard to edema and pain.
