Cholesteatoma is an abnormal skin growth or skin cyst trapped behind the eardrum, or the bone behind the ear. Cholesteatomas begin as a build-up of ear wax and skin, which causes either a lump on the eardrum or an eardrum retraction pocket. Over time, the skin collects and eventually causes problems like infection, drainage, and hearing loss. The skin may take a long time to accumulate and can spread to the area behind the eardrum (the middle ear space) or to the bone behind the ear, called the mastoid bone.
