Evaluation of a bone groove geometry for fixation of a cochlear implant electrode.

Purpose: Electrode migration is a rare, but relevant complication in cochlear implant (CI) surgery. An effective countermeasure is to create a bone groove in the facial recess to secure the electrode lead. We use this method routinely since 2013, but still experienced sporadic electrode migration events most likely due to an improper surgical execution.

The Effect of a Bone Groove Against Cochlear Implant Electrode Migration.

Hypothesis: The risk of electrode migration in cochlear implant (CI) surgery can be reduced by securing the electrode lead in a bone groove in the chorda-facial angle.

Background: Electrode migration is an important complication in CI surgery, which affects hearing performance, may induce pain and facial nerve stimulation, and requires surgical revision. A potential method to secure the electrode is to use a bone groove created in the facial recess to fixate the electrode lead.
