Abstract
Otosclerosis is a disorder of the bony labyrinth with usual onset in the third decade. The disease is bilateral in a majority of cases and such patients have conductive hearing loss. In case of fenestral otosclerosis hypodense foci are seen on CT/CBCT just anterior to the oval window, at the so-called fissula ante fenestram region. In case of retrofenestral otosclerosis additional foci are seen in the otic capsule around the cochlea.
