stapes footplate thickness in mm in the stapes axial plane
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
