Otitis media with effusion (OME) is defined as the presence of fluid in the middle ear in the absence of signs or symptoms of acute ear infection. The condition is very common, with one study reporting that about 90% of children will have an episode of OME before reaching school age.1 Children develop, on average, 4 episodes of OME every year. Synonyms for OME include ear fluid and serous, secretory, or nonsuppurative otitis media (OM). OME is largely asymptomatic, and many episodes are therefore undetected, including those in children with hearing difficulties or school performance issues. In contrast, acute OM (AOM) is the rapid onset of signs and symptoms of inflammation in the middle ear  with the accumulation of middle ear fluid, known as a middle ear effusion (MEE). Signs of middle ear inflammation include bulging or fullness of the tympanic membrane (TM), erythema of the TM, and possibly acute perforation of the TM with otorrhea. Symptoms of middle ear inflammation include otalgia, irritability, and fever. OME is most often asymptomatic.
