 Chronic Suppurative Otitis media is a chronic inflammation of the middle ear cleft characterized by ear discharge from a permanent perforation in the tympanic membrane. It has been classified into two types tubo–tympanic and attico–antral type depending upon whether the pars tensa is involved (former) or pars flaccida is involved (later). The perforations of pars tensa are again of two types – 1. Central and 2. Marginal. The Central tubo–tympanic perforations are considered as safe as they are usually not encountered with life threatening complications where as marginal perforations of pars tensa and attic perforations are considered as dangerous as they are often associated with life threatening complications.  The disease is more common in developing countries especially among low socio‑economic society because of malnutrition, overcrowding, poor hygiene, inadequate health care, and recurrent upper respiratory tract infection.
