Postoperative positional verification of the electrode array using measurements of the local evoked potential in patients with auditory brainstem implants

Introduction Electrode migration in patients with auditory brainstem implant (ABI) can lead to refusal to use the speech processor, especially in children. Imaging verification of electrode location is costly and also represents radiation exposure. For regular follow-up examinations, measurement of the local evoked potential (LEP) (Gärtner et al. 2021, DOI: 10.1371/journal.pone.0249535) is an alternative.
