Apr 29, · The Eustachian tube is the tunnel or channel connecting the middle area of the ear with the area at the back of your throat. Its main function is to drain the fluid as well as keeping the air pressure just right inside the ear.

Oct 03, · The eustachian tubes help regulate ear pressure and drain excess fluid from the middle ear, moving it to the throat to be eliminated. The canals in these tubes are tiny so blockages can happen for. Fluid collects in the middle ear when the eustachian tubes that help drain fluids from the inside of the ear to the back of the throat are partly or completely blocked.
