Benign tumor usually found in middle ear and mastoid region.EarEncyclopedia Entry for Cholesteatoma :Cholesteatoma. Cholesteatoma can be a birth defect (congenital). It more commonly occurs as a result of chronic ear infection. The eustachian tube helps equalize pressure in the middle ear. When it is not working well, negative pressure can build up and pull part of the eardrum (tympanic membrane) inward. This creates a pocket or cyst that fills with old skin cells and other waste material. The cyst may become infected or get bigger. This can cause the breakdown of some of the middle ear bones or other structures of the ear. This can affect hearing, balance, and possibly the function of the facial muscles.Symptoms include: Dizziness Drainage from the ear , which can be chronic Hearing loss in one ear Sensation of ear fullness or pressure.An ear exam may show a pocket or opening (perforation) in the eardrum, often with drainage.
