Conclusion
Prolonged intubation used in severe COVID-19 patients is associated with significant laryngeal disorders including laryngeal edema, posterior glottic stenosis, granuloma, laryngeal necrosis or vocal fold insufficiency. Patients with a history of >2-week intubation have a higher risk of posterior glottic stenosis, which may be managed medically or surgically. Future studies are needed to determine whether COVID-19 infection is associated with a higher risk of laryngeal injuries than other intubation causes.
