Chronic suppurative otitis media (CSOM) is a stage of ear disease in which there is chronic infection of the middle-ear cleft, i.e. the eustachian tube, middle ear and mastoid, and in which a non-intact tympanic membrane (e.g. perforation or tympanostomy tube) and discharge (otorrhoea) are present. The perforation can result as a complication or as sequelae of acute otitis media, trauma or extrusion or removal of a tympanostomy tube. Prevalence surveys, which vary widely in disease definition, sampling methods and methodological quality, show that the global burden of illness from CSOM involves 65 - 330 million individuals with draining ears, 60% of whom (39 - 200 million) suffer from significant hearing impairment.
