Treatment of acute vocal fold scar with local injection of basic fibroblast growth factor: a canine study

Abstract

Excised larynx measurements revealed significantly lower PTP and increased NMWA in bFGF-treated vocal fold. Elastica Van Gieson staining revealed less contraction of the bFGF-treated vocal fold. Histologic measurements revealed that the thickness of the lamina propria was significantly greater in the bFGF-treated vocal fold. Alcian blue staining revealed improved restoration of hyaluronic acid in the bFGF-treated vocal fold.
