Case 3. A, Oblique multiplanar reformatting of high-resolution MSCT of a HiFocus I electrode array without positioner. The reference electrode (R) projects proximal to the cochleostomy. All 16 electrode contacts are positioned within the cochlea. The electrode array courses along the lateral wall of the cochlear lumen over its entire length, leading to a less deep insertion than with the positioner (compare Fig 3). B, On a VR image, a rather shallow insertion of the electrode can be seen. M, modiolus.
