The effects of Eustachian Tube Dysfunction range from mild to severe and can be temporary or permanent. A retracted or sucked-in, often thinned ear drum, gives a sensation of being blocked, having pressure, ringing in the ears and even imbalance. Fluid in the middle ear can either be thin fluid (serous) or thick fluid (mucoid). This fluid can also be infected and result in pus. The symptoms obviously here will be deafness and pain. Thinning or ingrowth due to negative pressure can result in a cholesteatoma where the skin of the outer ear and drum migrate inwards to the middle ear or mastoid. There are symptoms similar to of those above and may include a discharge. In severe problems the facial nerve can be affected together with inner ear deafness, vertigo and even a brain abscess.
