Chronic laryngitis is a concern. If the a person has a change in his or her voice, or hoarseness that lasts more than 2 to 3 weeks, a doctor should be consulted. This long-term voice change could be caused by an easily treatable condition such as acid reflux or being exposed to a substance that continues to irritate the vocal cords. It might be the first sign of a serious condition, however, such as a tumor on the voice box that needs medical attention. The hoarseness may be due to a laryngeal papilloma on the vocal folds or more worrisome, a laryngeal cancer; other lesions that affect the recurrent laryngeal nerve may also cause hoarseness.
