- Effusion of the middle ear (MEE).
OM with effusion (OME), formerly termed serous OM or secretory OM, is MEE of any duration that lacks the associated signs and symptoms of infection (eg, fever, otalgia, irritability). OME usually follows an episode of AOM.
Chronic suppurative OM is a chronic inflammation of the middle ear that persists at least 6 weeks and is associated with otorrhea through a perforated TM, an indwelling tympanostomy tube (TT; see image below), or a surgical myringotomy.
