Laryngitis requires an examination by an otolaryngologist. It is an emergency in the field of otolaryngology and is common in infants and young children. It can cause sudden high fever in patients, with body temperature above 38.5℃, severe throat pain, breathing difficulties, and painful swallowing. In severe cases, it may also lead to a barking cough, choking, and even death. If a patient exhibits the above symptoms, an initial test with an electronic laryngoscopy can reveal significant congestion and edema of the vocal cords. In terms of treatment, laryngitis primarily requires symptomatic anti-inflammatory treatment to reduce inflammation. It is also necessary to locally apply corticosteroids to lessen the congestion and swelling of the vocal cords and avoid breathing difficulties. During treatment, the patient's breathing should be closely monitored, and if choking occurs, a tracheotomy may be needed. (Please use medication under the guidance of a professional physician and avoid self-medication.)
