Laryngeal Lesions Due to COVID-19

Laryngeal lesions due to COVID-19 were mainly minor inflammatory symptoms with no specific findings, until the emergence of Omicron variants. After the emergence of Omicron variants, the number of patients complaining of severe sore throat, dysphagia, hoarseness, and dyspnea increased rapidly. In these cases, laryngoscopic findings are characterized by the formation of sticky, mottled white plaque in the laryngeal vestibule and erythema and edema extending below the subglottis and into the trachea. Steroids and antivirals should be considered in cases of airway stenosis and dehydration due to feeding difficulties, even if the disease is classified as "mild" according to the Japanese severity scale.
