Can a cholesteatoma be from an ear infection or injury?

ANSWER

A cholesteatoma can happen for several reasons, including following an ear infection or injury. Sometimes after an operation on your ear, or because of a cold or allergy, your Eustachian tubes get weak and create a vacuum in your ear. This condition sucks in your eardrum, making it a sac -- the perfect place for skin cells to collect. Cholesteatomas caused by ear infections are the most common kind.
