What research is being conducted on disorders of vocal abuse and misuse?
Scientists are examining a multitude of issues related to vocal abuse and misuse. They are conducting in-depth studies of the tissues of the vocal folds to determine how various types of stress affect these delicate tissues. Scientists are especially interested in determining why vocal behaviors in some individuals lead to vocal nodules while similar behaviors in other individuals may lead to mild laryngitis, vocal polyps, or little or no voice change. They are also examining the tissue changes necessary for the development of laryngeal growths such as nodules and polyps, as well as laryngeal cancer, and how various treatments reverse those tissue changes. Speech-language pathologists are studying the effectiveness of behavioral techniques including use of machines to help people relearn proper vocal techniques such as good breath support or efficient use of the larynx. Studies that will improve the treatment of hyperfunctional voice disorders in children are also in progress. Of speci
