Tubotympanic cholesteatoma

Chronic suppurative otitis media is defined as a chronic inflammation of the mucoperiosteal lining of the middle ear cleft. It is described as a persistent disease that is insidious in onset, often capable of causing severe destruction with irreversible sequelae, and clinically present with hearing loss and discharge. It has been classified into tubotympanic (safe) and atticoantral (unsafe) perforation. Cholesteatoma always occur in the atticoantral type and in marginal perforation. We report a case of cholesteatoma that occurred as a tubotympanic type of perforation.
