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

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