[Cochlear assessment before cochlear implantation by computer tomography with a modified Stenvers projection]

In the study protocol of candidates for cochlear implantation, the patency of the cochlea should be assessed. Therefore we systematically add the Stenvers modified projection to the routine coronal and axial sections which permits the visualization in a single sation of practically all the coils of the cochlea. This projection also is useful in postoperative controls, to confirm the correct intracochlear position of the electrode.
