Office-Based Steroid Injection Following Laser Therapy for Benign Lesions of the Vocal Folds
摘要
Despite the advances in technology and the use of more refined instruments, scar formation remains a feared complication of microlaryngeal surgery [1]. With scarring, there is a change in the lamina propria extracellular matrix—mainly, an increase in collagen and a decrease in elastin, among other constituents. This change in the extracellular matrix reduces the pliability of the vocal fold and increases its stiffness. Risk factors for fibrosis and/or scar formation following microlaryngeal surgery are older age (above 50 years), duration of hoarseness of more than 6 months, and/or a lesion attached to the vocal ligament [2, 3].
