Fig 1. Scoring of the visibility of electrode contacts and anatomic structures: on a MPR perpendicular to the modiolus of an MSCT image of the implanted human cadaver temporal bone, the cochlea is divided in 4 quadrants (white crosslines). The quadrants are numbered counterclockwise, and the round window niche is located in the first quadrant (I-IV). A quantitative score from 0 to 2 was given to each electrode contact according to its visibility. Cochlear structures, such as the inner and outer wall, were scored per quadrant. The kinking of the electrode is localized in the third quadrant (arrow). b indicates basal turn of the cochlea at the level of the round window; v, vestibule, *horizontal semicircular canal (SCC); **superior SCC.
