Macroglossia secondary to prolonged prone positioning for management of COVID-19 respiratory failure.

We report the case of a 59-year-old woman who developed acute macroglossia following prolonged prone positioning for management of COVID-19. We found that Biotene mixed in glycerin was effective at removing keratinised lingual plaques and better tolerated than Biotene alone. Additionally, uniform tongue compression applied via tubular elastic dressing yielded more efficacious results than uneven tongue compression via Coban.
