Abstract
• Cholesteatoma may be acquired or congenital.
• Acquired cholesteatoma is the result of retraction pocket extension, invasion through a perforation, or trapped epithelium from a temporal bone fracture.
• Congenital cholesteatoma represents the isolation of squamous epithelial elements in the temporal bone during development. These are located in the middle ear, petrous apex, or mastoid compartment.
• As a rule, the cholesteatoma epithelial lining should be surgically removed although instances exist where marsupialization may prevent enlargement.
