A cholesteatoma is a type of cyst found in the middle ear behind the eardrum. It's a noncancerous tumor that forms when the skin grows through the hole in the middle of the ear. It can occur due to a damaged eardrum or a defect at birth.

Are You at Risk?
Factors that increase your risk of a cholesteatoma include:
- Chronic ear infections
- A poorly functioning eustachian tube
- Down syndrome
- Turner syndrome
- Cleft palate
- Abnormalities of the bones of the skull and face
- A family history of chronic middle ear disease or cholesteatoma
Symptoms of Cholesteatoma
- Hearing loss
- Discharge from the ear, sometimes foul-smelling
- Pressure in the ear
- Numbness of the ear
- A sensation of spinning
- Muscle weakness in the face on the affected side
Your doctor will ask about your symptoms and medical history and perform a physical exam. Images may be taken of your middle ear and surrounding structures. This can be done with:
- CT scan
Your doctor may test your nerve function through:
- Hearing tests and balance tests
- Caloric stimulation
Treatment for Cholesteatoma
If the tumor goes untreated, serious complications may occur that include:
- Hearing loss
- Muscle weakness
- A spinning sensation known as vertigo
Your doctor uses a scalpel or a needle and a syringe to thoroughly clean the ear and remove fluid and bacteria. You'll be given eardrops to prevent the infection from returning.
You're likely to recover fully without complications if the tumor is caught and treated early with surgery.
Medications are necessary to dry the fluid in the ear if allergies or other causes are producing excess fluid.
