Acute laryngitis is a common clinical condition of acute upper respiratory tract infection, which usually returns to normal after 5-10 days of treatment. Acute laryngitis is an acute non-specific inflammation of the mucous membrane and vocal cords of the larynx, which occurs in the winter and spring. Patients mainly present clinically with cough, hoarseness, laryngeal pain, and in severe cases, inspiratory dyspnea. Patients are advised to apply systemic antibiotics (penicillins and cephalosporins are the most effective) and local nebulizer inhalation treatment as soon as possible to control the infection in the body; at the same time, glucocorticoid treatment is used according to the patient’s weight to quickly eliminate the swelling of the larynx and avoid asphyxia, which can be recovered in 5-10 days after active treatment. However, patients need to be aware that acute laryngitis should be treated thoroughly, and if the condition recurs, it may lead to vocal fold polyps and chronic laryngitis. In addition, acute laryngitis usually occurs after excessive use of the voice. Patients also need to control the use of the voice and speak as little as possible in their daily lives to prevent laryngitis.
