Ear Cholesteatoma
   Cholesteatoma is an abnormal skin growth that can develop in the middle section of ear, behind the eardrum. Cholesteatoma is usually caused by frequent infections of the ear that can develop inward the skin of the eardrum. Cholesteatoma is often like a sack that emits the old skin layers which are formed in the inner ear. Cholesteatoma can be enlarged as a pile and damage the ossicles of the middle ear. Prolonged growth of cholesteatoma can cause hearing loss, dizziness, and paralysis of face muscles. 


   Cholesteatoma Etiology 
    Cholesteatoma is often formed by dysfunction of eustachian tube and infection of the middle ear. Eustachian tube balances the air between the middle ear and environment. When eustachian tube is not functioning properly, (probably because of allergy, cold or sinusitis) the air of the middle ear is absorbed by the body and a relative vacuum is formed in the ear. The pressure caused by the vacuum sucks the sack (especially in areas of the eardrum which have already been weakened by infection) inside which is often changed into cholesteatoma.
   Congenital cholesteatoma is rare. It has already been from the birth. It can be occurred in basal skull bones and around the ear. Congenital cholesteatoma can be seen beyond the eardrum. 

    Cholesteatoma Symptoms 
    Infection which is sometimes smelly might be seen at first. As Cholesteatoma sack is developing, hearing decrease or pressure might be felt in the ear simultaneously. A pain behind the ear, especially at night, might severely bother the patient. Dizziness or muscle weakness might occur at the same side. All or one the above symptoms is a good reason for more examination. 

   Is cholesteatoma dangerous?
   Ear cholesteatoma can be dangerous and should never be ignored. Erosion of the bone can cause the infection to develop to the areas (like inner ear and brain). If treatment is not on time, deafness, abscess, meningitis, and rarely death may occur.
