Vocal fold (voice box) paralysis is a major cause of voice and swallowing disorders. Current treatments are not highly effective because they fail to restore normal vocal fold motion. Dr. Halum's Neurolaryngology Laboratory in the Indiana University Department of Otolaryngology is focused on developing better treatment options for vocal fold paralysis. They are currently working with muscle stem cells (myoblasts) to determine if they could be programmed to orchestrate nerve regeneration toward paralyzed vocal folds. Such work may not only be applicable to vocal fold paralysis, but also other sites of paralysis throughout the body.
