Cholesteatoma

Cholesteatoma is a type of skin cyst that is located in the middle ear and mastoid bone in the skull.

Cholesteatoma can be a birth defect (congenital). It more commonly occurs as a complication 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:

An ear exam may show a pocket or opening (perforation) in the eardrum, often with drainage. A deposit of old skin cells may be seen with a microscope or an otoscope -- a special instrument to view the ear. Sometimes a group of blood vessels may be seen in the ear.

The following tests may be performed to rule out other causes of dizziness:

Cholesteatomas very often continue to grow if they are not removed. Surgery is most often successful. However, you may need the ear cleaned by a health care provider from time to time. Another surgery may be needed if the cholesteatoma comes back. If you think you may have a Cholesteatoma, call to make an appointment to see one of our physicians - 361-573-4331.
