Surgery is needed to remove the cyst.
Cholesteatomas usually continue to grow if not removed. Surgery usually works, but you may occasionally need the ear cleaned by a health care provider. Additional surgery may be needed if the cholesteatoma comes back.
Call your health care provider if ear pain, drainage from the ear, or other symptoms occur or worsen, or if hearing loss occurs.
