Abstract:
Voice disorders are among the most common communication disorders across the lifespan. Voice problems involve physical injury and have serious psychological, emotional, functional and economic consequences. In normal phonation, the vocal fold mucosa and ligament undergo vibrations at frequencies ranging from 20 to 3kHz and amplitudes of a few millimeters. Recent advances have improved our understanding of physical and biological mechanisms in vocal fold injury and repair. However, much work remains to link these mechanisms, to uncover essential mechanical and biological factors in pathogenesis and treatment responses for voice disorder. One challenge is to develop non-invasive tools to measure the mechanical stresses during phonation in vivo and the ensued biological response in human. In this talk, novel technologies and approaches we have developed for humans, animals and computer models to surmount current barriers will be described.
