How is a CT scan (computerized tomography) used to diagnose a cholesteatoma?

ANSWER

A CT scan is a series of X-ray images that show your doctor a detailed picture of the bones, blood vessels, and soft tissue inside your ear. This can tell your doctor if your cholesteatoma has grown into the bones of your ear, which can mess with your hearing and balance. Your doctor may especially want to do this scan if surgery might be a treatment option for you. It can give him a better picture of what's going on before the procedure.
