Letter to the editor: COVID-19 findings revealed via otolaryngological examination: Findings of a Japan Otorhinolaryngologist Association questionnaire

We conducted a survey on patients diagnosed with COVID-19 in December 2020. However, since the emergence of the omicron (B.1.1.529) variant in early 2022, COVID-19 is mainly characterized by upper respiratory tract inflammatory symptoms rather than those of the lower respiratory tract. There are also high rates of redness and edema of the pharyngolaryngeal mucosa, especially lateral bands, which can be observed through visual examination of the oral cavity and pharyngolarynx. In addition, COVID-19 caused by the omicron variant is characterized by the formation of a sticky, mottled white coat in the laryngeal vestibule, and erythema and swelling extending below the glottis and into the trachea [1].
