Laryngitis can cause fever and is considered an emergency in otolaryngology, prevalently seen in infants and young children. It can lead to sudden high fever, with temperatures above 38°C, severe throat pain, hoarse voice, bark-like coughing, and in severe cases, it can cause breathing difficulties, and even lead to choking and death. Examination may reveal evident congestion and swelling of the bilateral vocal cords, and incomplete closure of the glottis, resulting in the hoarseness of the voice. In terms of treatment, it is primarily necessary to use anti-inflammatory treatment targeted at symptoms, as laryngitis is generally caused by a bacterial infection, so patients can effectively use oral cephalosporin antibiotics. Additionally, corticosteroids are also used to reduce local congestion and swelling. During treatment, it is essential to closely monitor the patient's temperature and respiratory condition. If the temperature exceeds 38.5°C, antipyretic medication should be administered, and in cases of breathing difficulties, tracheotomy may be necessary. (Medications should be used under the guidance of a doctor.)
