[Presence or absence of bacteria in otitis media with effusion?].

Otitis media with effusion (OME) is an inflammation of the middle ear containing serous or mucoid secretion, an intact tympanic membrane, and no clinical signs of acute infection, which results in mild to moderate hearing loss. Consequently, a child with OME may have a poor school performance, being regarded as inattentive, in addition to asking others to repeat what they have just said and listening to television at a loud volume.
