I’m a little surprised they went to a press release but didn’t say they identified a structure in a cadaver. So, at the moment, this is sort of like a geological feature that’s only ever been seen using a satellite.
"These tubarial glands were seen to exist in the PSMA PET/CT scans of all the 100 patients examined in the study, and physical investigations of two cadavers – one male and one female – also showed the mysterious bilateral structure, revealing macroscopically visible draining duct openings towards the nasopharyngeal wall."
I mean this question with genuine curiosity
