This study examined how intracochlear voltage distributions obtained from impedance field telemetry (IFT) in cochlear implant (CI) users with straight lateral wall electrodes related to electrically evoked cervical and ocular vestibular myogenic responses (e-cVEMPs and e-oVEMPs).
Findings are preliminary; if replicated, intracochlear voltage mapping via impedance field telemetry may help clinicians identify CI users at risk for electrically evoked vestibular (balance) side effects, but no programming or fitting change is warranted yet.
Electrically evoked vestibular responses are a known but poorly understood side effect of cochlear implantation; a reliable predictive measure could improve patient counseling and electrode programming to reduce dizziness.
