Özet
Objectives. Platelet-rich plasma (PRP) is a reliable and has low side-effect profile and has beneficial effects on wound healing. Its investigatory effects on wound-healing process were shown on various tissues. The aim of the present study was to evaluate effectiveness of PRP application on scar tissue of acute vocal fold injury. Materials andmethods. Twenty-fourWistar rats were used in the study. The entire layer of the lamina propria down to the thyroarytenoid muscle of 10 subjects was unilaterally injured by with a microscissor. Gelfoam-absorbed PRP was applied on the injured area for 10 minutes. Control group consisted of rats unilaterally injured using a microscissor, and gelfoam with normal saline was applied on the injured area. Following sacrifice, the larynxes were carefully dissected and removed for histopathologic examination. After excised larynx experiments, serial sections were prepared from vocal fold. Hematoxylin eosin and immunohistochemical staining were done for epithelial growth factor receptor (EGFR), fibroblast growth factor receptor (FGFR1), and vascular endothelial growth factor (VEGF) staining for histopathologic examinations. Results. There was not a significant difference between the two groups for lymphocyte. Although collagen and VEGF were higher in the study group, there was not a significant difference between the groups (P > 0.05). There was a significant difference between control and study groups for EGFR and FGFR1(P < 0.05). Conclusions. PRP has beneficial effects on wound healing. PRP accelerates epithelization of injured rat vocal folds by inducing EGFR secretion. PRP is an autogenous, reliable, low side-effect profile, easily harvested material. PRP may be useful to prevent scar formation.
