ACE2 and infectious otitis media: High levels of ACE2 are expressed in nasal respiratory epithelium goblet, basal and ciliated cells.5 Because of the enriched populations of ciliated cells, glands and goblet cells in the inferior part of the Eustachian tube,6 we suggest that this portion of the tube can be a potential route for SARS-CoV-2, causing infection of the middle ear.
