Abstract (original English)

Minimally invasive voice-preservation techniques, including microlaryngoscopy, phonosurgery, and office-based regenerative interventions, have revolutionized the management of benign and early-stage laryngeal disorders by minimizing fibrosis and preserving phonatory function. However, the long-term (>6 months) wound healing and extracellular matrix (ECM) remodeling dynamics that determine sustained vocal outcomes remain poorly understood, particularly among professional singers who experience high vibratory demand. Moreover, African American and minority singers continue to face significant barriers to specialty laryngology care, underrepresentation in research cohorts, and disparities in insurance coverage, creating inequities in both access and postoperative outcomes. This review synthesizes evidence on chronic wound healing and ECM remodeling following minimally invasive voice-preservation procedures, emphasizing histologic integration, molecular mediators of fibrosis, and correlations with objective (dysphonia severity index, vocal extent measure, and maximum phonation time) and subjective (voice handicap index, singing voice handicap index) recovery metrics. It also examines racial and socioeconomic inequities in laryngeal care among professional voice users. Our method for this research was to use PubMed, JStor, Web of Science, and Cochrane Library databases starting from
