Benign Neoplasms Malignant Neoplasms Laryngitis Inflammation of the larynx. Laryngitis may also occur in bronchitis, pneumonia, influenza, pertussis, measles, and diphtheria. Excessive use of the voice, allergic reactions, and inhaling irritating substances, such as cigarette smoke, can cause acute or chronic laryngitis. An unnatural change of voice is usually the most prominent symptom. Hoarseness and even aphonia, with a sensation of tickling, rawness, and a constant urge to clear the throat, may occur.
Symptoms vary with the severity of the inflammation.
Indirect laryngoscopy discloses mild to marked erythema of the mucous membrane, which may also be edematous. There is no specific treatment for viral laryngitis. Voice rest and steam inhalations relieve symptoms and promote resolution of acute laryngitis. Treatment of acute or chronic bronchitis may relieve laryngitis. Chronic bronchitis may require a broad-spectrum antibiotic, such as ampicillin 250 or 500 mg or tetracycline 250 mg po q 6 h for 10 to 14 days.
