Cholesteatoma is an abnormal skin growth in the\nmiddle ear behind the eardrum that may also affect the mastoid (skull bone). It\nbegins as a cyst that gradually increases in size, destroying the bones of the\nmiddle ear and causing hearing loss. <\/p>\n\n\n\n

When the Eustachian tube is functioning\nnormally, it equalizes ear pressure by moving air from the back of the nose\ninto the middle ear. Allergies and viruses can affect performance, leading to a\npartial vacuum in the ear. <\/p>\n\n\n\n

This negative pressure stretches the eardrum,\ncreating a pocket or cyst that fills with old skin cells and waste material,\nwhich can become easily infected. In rare cases, cholesteatoma can be\ncongenital (present at birth). <\/p>\n\n\n\n
