What causes a cholesteatoma?

ANSWER

The most common cause of cholesteatomas are ear infections. Sometimes an operation on your ear, or a cold or allergy can make your Eustachian tubes 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.
