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.
Fluid behind the eardrum is called serous otitis media. It can create pain and hearing difficulty similar to a middle ear infection. The eardrum can rupture (break) in severe cases of ear barotrauma, causing bleeding or leaking of fluid from the ear. A ruptured eardrum can result in hearing loss. In severe cases, it is possible for the pressure to create a leak between the deepest structures of the ear (the fluid-filled bony canals called the cochlea and semicircular canals) and the inner ear space.
