The majority of patients with pharyngitis do not lose their voices. Most of them lose their voices because of the seriousness of pharyngitis, which involves the mucous membrane in the patient’s larynx, resulting in laryngitis and congestion and edema of the vocal cords. In terms of treatment, patients are advised to do nebulization, which can reduce the congestion and edema of the mucous membrane in the larynx and improve the hoarseness of the patient’s voice, and can also take oral hormonal drugs such as dexamethasone and prednisone. If the loss of voice is accompanied by severe sore throat and difficulty in breathing, patients can go to the hospital for further treatment as soon as possible.
