This poster explores how glottic insufficiency, characterized by incomplete vocal fold closure, affects vocal production in singers. It highlights the multidisciplinary approach to diagnosing and treating conditions like vocal fold atrophy, paralysis, and sulcus vocalis. This poster will provide resources and strategies for creating evidence-based, functional interventions that align with the specific goals of singing voice clients.
