Intraoperative Finding of Cholesteatoma in Central Tympanic Perforation

Abstract

On the other hand, when we talk about the chronic cholesteatomatous otitis media, we refer to the accumulation of desquamative keratinized epithelium, either in the tympanic cavity or in the mastoid bone, which may be secondary to an eardrum perforation but may also occur as a primary lesion [1]. Marginal perforations are considered to be more dangerous because they are usually associated with the development of a cholesteatoma [2]. In this type of perforations, the stratified squamous epithelium of the external auditory canal can grow into the middle ear and form a cholesteatoma [3].
