Updated June 14, 2016. Fluid in the ear, also called serous otitis media (SOM) or otitis media with effusion (OME), is usually the result of an ear infection, but it can occur under any condition in which the auditory tube (eustachian tube) is impaired. The auditory tube allows fluid to drain from the ear into the back of the throat. If the auditory tube becomes clogged, fluid will become trapped in the middle ear space. This fluid is called an effusion by your healthcare providers. In addition to ear infections, the common cold and allergies can often lead to fluid in the ear.
Otitis media with effusion (OME) is thick or sticky fluid behind the eardrum in the middle ear. It occurs without an ear infection. The Eustachian tube connects the inside of the ear to the back of the throat. This tube helps drain fluid to prevent it from building up in the ear. The fluid drains from the tube and is swallowed. Otitis media with effusion (OME) and ear infections are connected in two ways: After most ear infections have been treated, fluid (an effusion) remains in the middle ear for a few days or weeks.
