SECTION TWO | CLINICAL GUIDANCE

To ascertain electrode location (base or apex):

1. Select one active electrode mid-way along each array (e.g. 6 and 17 with

a full insertion of both arrays) using the channel check tick boxes. Use

the ‘Balance’ function to stimulate the two electrodes and deactivate all

remaining electrodes. If the electrode array is inserted as recommended,

pitch should decrease with increasing electrode number. Electrode arrays

that have been switched (i.e. basal array in the apex) will have the opposite

pitch order.

2. Repeat this test on different electrode pairs in the base and apex to conﬁrm

tonotopicity. If results are not repeatable, an x-ray should be performed.

Test the MAP in live-voice mode and make any necessary adjustments.

For more detailed information on the various surgical approaches and how

these will affect programming the implant, please refer to the Programming

Guide for the Nucleus 24 Double Array provided by Cochlear.
