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 2000. The study will include randomized controlled trials and observational cohorts and case series with ten or more patients and previous systematic reviews that focus on wound healing and functional outcomes and access disparities. Two reviewers will conduct independent screening and data extraction, while thematic synthesis will be used to organize existing evidence and identify areas where more research is needed. Existing studies demonstrate consistent short-term improvement in acoustic and perceptual metrics but limited histologic data beyond 9-12 months. Available human biopsy findings reveal fibroblast infiltration and partial ECM integration (eg, silk-hyaluronic acid hydrogels, adipose-derived stromal vascular fraction therapy), yet lack quantitative analysis of collagen I/III ratios, elastin content, and viscoelastic restoration. Professional singers remain largely excluded from histologic or biomechanical cohorts. Persistent racial and geographic disparities further limit access to specialized voice-preservation surgery and longitudinal follow-up. Long-term remodeling after minimally invasive voice-preservation procedures remains underexplored, with crucial gaps in linking tissue biomechanics to clinical outcomes and health equity.

However, the anatomical distribution pattern of BoNT following supraglottic injection and the predominantly affected intrinsic laryngeal muscles have not yet been clearly elucidated, owing to a lack of detailed anatomical investigations. Thirteen fresh human cadavers (seven males and six females; mean age, 77.0 years) were included in this study. After harvesting the larynx, a supraglottic injection was performed under direct anatomical visualization using a blue dye as a tracer. Injection volumes of 0.4 mL and 0.2 mL were administered bilaterally. Following passive simulation of laryngeal adduction and abduction, specimens were frozen at -80 °C and sectioned coronally. Dye distribution was analyzed with a primary focus on the thyroarytenoid (TA) muscle complex, including the aryepiglottic muscle fibers, main TA muscle, vocalis muscle, and diffusion to other intrinsic laryngeal muscles. In all specimens, the dye remained confined to the supraglottic soft tissues, with no extension to the structures outside the larynx. At the muscular level, the dye involvement was limited to the TA muscle complex. The dye was consistently observed along the aryepiglottic muscle fibers and extended toward the main TA muscle. Partial intramuscular spread into the main TA muscle was identified in 50% of specimens in both injection volume groups (0.4 and 0.2 mL). Minimal extension into the vocalis muscle was observed in 33% of specimens. In contrast, no dye diffusion into the lateral cricoarytenoid, posterior cricoarytenoid, or interarytenoid muscles was observed in any of the specimens. Although the extent of dye spread varied according to injection volume, the pattern of muscle involvement was similar between the two groups. The mean distance from the supraglottic injection site to the TA muscle was 12.9 ± 1.7 mm. Supraglottic BoNT injections preferentially involve the thyroarytenoid muscle complex, with limited extension into the vocalis muscle and no diffusion into the other intrinsic laryngeal muscles.
