Abstract
Inflammation of the middle ear cleft is a disease of great interest both from clinical and radiological points of view. The attic floor (tympanic diaphragm), tympanic isthmus, and the aditus ad antrum play an important role in inflammatory processes of the middle ear cleft. The computed tomographic (CT) appearances of chronic otomastoiditis, tympanosclerosis, cholesterol granuloma, attic retraction pocket, and acquired cholesteatoma are reviewed and illustrated. The role of magnetic resonance imaging (MRI) in the evaluation of chronic ear disease and cholesteatoma will be discussed.
