Brief summary
The aim of this study is to compare the thickness of the stapes footplate measured with ultra high resolution CT in control patients, otosclerosis patients and chronic otitis media patients.
Detailed description
Stapes footplate thickness will be measured under its anterior crus, its posterior crus and at its midpoint, in both the stapes axial plane and the laletral semi-circular canal planes.

|---|---|---|
| stapes footplate thickness in mm in the stapes axial plane | october 2020-october 2022 | stapes footplate thickness measured with a digital caliper on our PACS system with the accuracy of a tenth of a millimetre, under the anterior crus of the stapes, under the posterior crus of the stapes, and at its midpoint, in the stapes axial plane and in the lateral semi circular canal plane, to compare both values and find out wich one is the most pertinent |
