Anatomy of the Condition
Vocal fold misuse and abuse can cause a variety of problems beyond hoarseness. In cases of muscle tension dysphonia (hoarse voice), excessive tension in and around the muscles of the larynx leads to an abnormal voice. Prolonged phonotrauma can cause swelling of the vocal folds or development of vocal fold nodules, vocal fold polyps or vocal fold cysts (benign masses of the larynx). Screaming or other extreme vocal activity may even cause a hemorrhage of the vocal folds.
