Regular position of the electrode array. A, One-millimeter MIP reconstruction of the cochlea shows the basal turn (bt), medial turn (mt), and apical turn (at). The position of the electrode array is clearly identified in the scala tympani (the scala tympani is basal; the scala vestibuli is apical). B, The insertion depth by using 5-mm MIP reconstruction in the horizontal reference plane reaches position 11, which refers to 451°–495° (Fig 1). All 12 electrodes (dots) can be identified on the electrode array.
