In this article the doctors treat the PET by insufflation of salicylic acid and boric acid into the eustachian tube.

This caused an inflammatory swelling which closed the tube. Sodium chloride seems to have the same effect.

But I suppose the boric acid works in a different way. Boric acid is known to be antifungal.

So what if we have a chronic fungal/yeast infection in the nasopharyngeal space? Maybe Candida auris?
