Hi,

I have heard or read of the word “shrinking” or “shrinkage” in relation to the Eustachian tube . It was used when the tube was congested or clogged and it meant that the inner lining of the tube had shrunk or returned to normal with either yawning, decongestants etc, or a Doctors intervention. It doesn’t actually shrink from its normal “healthy” size. I liken it to a swollen ankle that will shrink to it’s normal size when elevated or iced. The word can be misleading when thrown around.

That’s about it for what I learned.
