title: Section four: laryngitis and dysphonia.
abstract: Acute laryngitis is most often caused by viral illnesses through direct inflammation of the vocal cords or from irritation due to postnasal drainage. Bacterial infections, such as acute epiglottitis, also can cause dysphonia but typically have other systemic symptoms as well as respiratory distress. Chronic laryngitis is characterized by symptoms lasting more than 3 weeks. Chronic vocal cord issues can be related to overuse or stress on the vocal cords resulting in nodules or polyps. Individuals in certain occupations, such as singers, school teachers, and chemical workers, are at greater risk of chronic laryngitis. The diagnostic approach to chronic laryngitis should include visualization of the vocal cords to rule out potential malignant lesions. For acute and chronic overuse symptoms, the best treatment is vocal rest. The use of antibiotics or decongestants should be discouraged.
