Ear tubes are small plastic tubes which are inserted through the eardrum to provide ventilation of the middle ear space. They are usually shaped like a small grommet or rivet with a hole in the center.
Ear tubes function as an artificial eustachian tube.
The eustachian tube runs from the middle ear to the upper part of the throat. Normally, it allows air into the middle ear and fluid out of the middle ear. However, when the eustachian tube does not function properly, the middle ear can fill with fluid and the eardrum can become retracted. Although middle ear infections are a common problem, especially in children, they can become excessive or recur despite antibiotics. When this happens, they can cause prolonged discomfort or even lead to more serious complications.
