As one of the key fibrous proteins in the extracellular matrix, collagen plays a significant role in the structural and biomechanical characteristics of the vocal fold. Anchored fibrils of collagen create secure structural regions within the vocal folds and are strong enough to sustain vibratory impact and stretch during phonation. This contributes tensile strength, density, and organization to the vocal folds and influences health and pathogenesis. This review offers a comprehensive summary for a current understanding of collagen within normal vocal fold tissues throughout the life span as well as vocal pathology and wound repair. Further, collagen's molecular structure and biosynthesis are discussed. Finally, collagen alterations in tissue injury and repair and the incorporation of collagen-based biomaterials as a method of treating voice disorders are reviewed.
作为细胞外基质中的关键纤维蛋白之一,胶原蛋白在声带的结构和生物力学特性中发挥着重要作用。胶原蛋白的锚定纤维在声带内形成安全的结构区域,并且足够坚固,能够在发声过程中承受振动冲击和拉伸。这为声带提供了拉伸强度、密度和组织结构,并影响健康和发病机制。本综述全面总结了目前对正常声带组织在整个生命周期内的胶原蛋白以及声带病理学和伤口修复的理解。此外,还讨论了胶原蛋白的分子结构和生物合成。最后,综述了组织损伤和修复过程中胶原蛋白的变化,以及将基于胶原蛋白的生物材料作为治疗嗓音障碍方法的应用。
