Functional Collagen Scaffold for Laryngeal Soft Tissue Regeneration

Unilateral vocal cord paralysis (UVCP) is a clinical condition and often leads to glottic insufficiency. The presence of glottic insufficiency can result in poor pronunciation quality, vocal fatigue, shortness of breath with speaking, and in some cases, it could lead to unable to pronounce, dysphagia and aspiration, severely decreasing quality of life for its victims. This study is carried out to explore the short-term and long-term efficacy of the functional collagen scaffold in guiding laryngeal soft tissue regeneration.
