Overview

Conductive hearing loss is very common and the incidence increases with age. Until now, the scanner was the reference examination in the etiological diagnosis of deafness.

When performing a CT scan of temporal bones for the etiological diagnosis of conductive hearing loss, the quality of the image depends on the scanner brand and the acquisition parameters.

The investigators wish to show the usefulness of the cone beam in the diagnosis of conductive hearing loss
