COVID-19 Omicron variant-induced laryngitis

Collaboration between generalist and ENT physicians in COVID-19 Omicron variant-induced laryngitis

“…However, laryngoscopy, an irritant and a risk factor for airway emergencies by itself, is generally required to rule out acute epiglottitis. Additionally, laryngitis and not epiglottitis can result in airway emergencies, as reported by Kimura et al [1] . The limited number of physicians and institutions that can perform fiberoptic laryngoscopy or emergency airway management, which means that most COVID-19 patients visit general outpatient clinics without otolaryngologists.…”

“…We recently read, with great interest, a case report of subglottic laryngitis induced by coronavirus disease (COVID-19) Omicron variant by Kimura et al published in Auris Nasus Larynx, from the perspective of a general internist, engaged in hospital and emergency medicine [1] . Since the Omicron variant, especially the BA.5 variant, has become prevalent in Japan, the number of cases presenting with severe pharyngalgia appears to be increasing, as described by the authors.…”

“…Regarding the treatment, systemic administration of corticosteroids appears effective in the primary care setting. The authors raise concerns regarding administering steroids to patients with COVID-19 without oxygen demand [1] . Certainly, the administration of steroids for mild COVID-19 is not recommended in the treatment guidelines for COVID-19.…”

“…Kimura et al highlighted the risk of asphyxiation among COVID-19 patients with laryngitis [1] . That is, admitting the patient to the hospital would be appropriate for observation until the disease is stabilized.…”

Singing in and out of COVID

“…Since the physical act of voice production relies on integrity and balance between the three key components of power (respiration), source (phonation) and filter (resonance), any compromise to the form and/or function of the vocal tract can hamper the vocal output. Although it seems that some strains may have a propensity for different parts of the airway/vocal tract, with Omicron variant proposed to most affect the larynx/pharynx, 11 , 12 COVID‐19 symptoms can occur across all three voice components.…”
