Introduction Chronic otitis media (COM) is an inflammation of part or all of the mucoperiosteal lining of middle ear cleft. The disease has two types; mucosal and squamous (cholesteatoma). Most perforations of pars tensa are central indicative of mucosal disease. All attic disease and marginal perforations are indicative of squamous disease. The typical feature of squamous disease is the presence of a cholesteatoma (Keratinizing squamous epithelium) in the middle ear cleft.1 The bony involvement by the disease may give rise to granulation or polyp. Round window membrane is the only soft tissue barrier separating the middle ear from the inner ear. This semipermeable membrane appears to be the main portal for the passage of noxious substances…show more content…
