High-resolution CT scanning accurately depicts the status of the structures of the temporal bone, allowing delineation of pathology prior to surgical exploration of ears with cholesteatoma. It provides information concerning location and extent of disease as well as possible anatomic variations and complications that may be encountered. The main advantages of CT scanning over polytomography are superior soft-tissue contrast resolution and improved spatial detail at a reduced radiation dose for the patient.
