Video endoscopic finding of acute laryngitis caused by SARS-CoV-2 during the Omicron variant wave

A 44-year-old male, who was diagnosed with SARS‑CoV‑2/Omicron variant, reported strong sore throat and difficulty swallowing after hospitalization. The rhino-laryngo flexible video endoscopy, which was conducted for excluding acute epiglottis, showed necrotic legion localized to the supraglottic, glottic and subglottic area, and mildly edematous arytenoids. Meanwhile, no findings of acute epiglottitis were found. Based on the endoscopic findings, I considered that acute laryngitis was caused by Omicron variant, and strong sore throat and difficulty swallowing were developed. He received an oral painkiller and no supplemental oxygen were administered. After several days, his symptoms resolved. The Omicron variant is more likely to infect the upper respiratory tract than the lower respiratory system, and main symptoms caused by the Omicron variant consist of upper respiratory tract symptoms, such as sore throat. The diffuse necrotic lesion seen in the larynx in this case could be a characteristic of acute laryngitis caused by the Omicron variant.
