Interest of the Cone Beam Scanner of Temporal Bones in the Analysis of Conductive Hearing Loss (Cone-Beam)

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

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Show retrospectively that the superiority of the cone beam over the scanner in the diagnosis of conductive hearing loss	This superiority is based on the quality of the images allowing the visualization of the different elements of the middle and inner ears: Ossicles, windows, nerves (VII and VIII), cochlea, labyrinth	Files analysed retrospectively from January 01, 2018 to December 31, 2020 will be examined
