Effects of hyaluronic acid-collagen nanofibers on early wound healing in vocal cord trauma

Vocal cord scarring is the most crucial obstacle in voice quality after surgery. This study aimed to evaluate the effectiveness of hyaluronic acid (HA)-collagen nanofibers on the healing of vocal cords after surgical trauma. Right vocal cords of 12 New Zealand white rabbits were traumatized, and the experimental group was received 1.08 mg/75 ml topical HA-collagen nanofiber (Gelfix® spray) for 3 days. Three animals in each group were sacrificed...
