An evaluation of the effect of the use of platelet-rich fibrin on tonsillectomy results.

The aim of this study was to investigate the effect of liquid platelet-rich fibrin (PRF) during tonsillectomy on postoperative results. This study included 41 patients who underwent tonsillectomy between April 2022 and January 2023. Liquid-PRF at a dose of 1 ​cc was injected to three different points of one of the tonsil fossae, selected at random intraoperatively. The same amount of physiological saline was injected to the symmetrical points on the opposite tonsil fossa using the same size injector. Pain, wound healing, and bleeding were evaluated on postoperative days 1, 7, and 14. The data of both sides were compared statistically as the study and control sides. The pain scores were the highest for both sides on postoperative day 1, and gradually decreased in the following days, with no significant difference determined between the sides (p ​> ​0.05). Wound healing rates in the 1st week and 2 ​nd ​week were similar for both sides. Although there were more patients who have 100 ​% epithelization in the PRF group on the postoperative day 14, the difference between the groups was not statistically significant (p ​> ​0.05). The injection of PRF following tonsillectomy had no significant effect on postoperative pain, wound healing, or bleeding. [ABSTRACT FROM AUTHOR]
