PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - Acute otitis media (AOM) is defined as an acute illness marked by the presence of middle ear fluid and inflammation of the mucosa that lines the middle ear space. Otitis media with effusion (OME) is defined by the presence of middle ear fluid without acute signs of illness and usually follows AOM but may also occur as a result of barotrauma or allergy. Synonyms for OME include serous otitis, secretory otitis, glue ear, and middle ear catarrh. Less common chronic variations of otitis media include permanent perforation of the tympanic membrane, and perforation or retraction of the tympanic membrane with trapped epithelium that is unable to spontaneously clear desquamated debris, forming a cholesteatoma. This may occur in the presence of an intact tympanic membrane. Both perforations and cholesteatoma may be associated with recurrent foul-smelling otorrhea, termed chronic suppurative otitis media.
