Cholesteatoma is a serious medical problem. Early treatment is vital for the best outcome. Serious complications may occur if the tumor goes untreated, including
vertigo. Spreading of infection to the brain can lead to meningitis
and brain abscess.
Cholesteatoma responds well to treatments. Patients are likely to recover fully without complications if the tumor is caught and treated early. Talk with your doctor about the best treatment plan for you. Treatment options include:
Thorough cleaning of the ear is necessary to remove fluid and bacteria. Eardrops are also usually administered.
Surgery may be necessary if the tumor is threatening hearing or balance.
Medications are necessary to dry the fluid in the ear. Ear drops and oral antibiotics are often prescribed. Antibiotics will eliminate any infection in the ear.
Cholesteatomas caused by congenital defects cannot be prevented. However, proper treatment of ear infections can prevent cholesteatoma.
