Cholesteatoma is a destructive lesion that progressively expands in the middle ear, mastoid or petrous bone and leads to destruction of the nearby structures. Erosion, which is caused by bone resorption of the ossicular chain and otic capsule, may cause hearing loss, vestibular dysfunction, facial paralysis and intracranial manifestations
Cholesteatoma has three Classical forms: (1) Congenital, primary or genuine cholesteatoma: occurs behind an intact tympanic membrane. Primary acquired cholesteatoma: looks like a limited diverticulum of the pars flaccida with little or no history of otorrhea. Secondary acquired cholesteatoma: develops with posterosuperior perforations in eardrum and expansion of the disease process into the antrum, mastoid, attic and middle ear. Granulation tissue, polyps and foul- smelling otorrhea are common findings in this type
