Anodic Polarity Minimizes Facial Nerve Stimulation as a Side Effect of Cochlear Implantation

alexandrossfakianakis shared this article with you from Inoreader Anodic Polarity Minimizes Facial Nerve Stimulation as a Side Effect of Cochlear Implantation via JARO - Journal of the Association for Research in Otolaryngology via MedWorm.com AbstractOne severe side effect of the use of cochlear implants (CI) is coincidental facial nerve stimulation (FNS). Clinical methods to alleviate FNS range from the reprogramming of processor settings to revision surgery. We systematically assessed different changes in CI stimulation modes that have been discussed in the literature as "rescue factors" from FNS: electrode configuration (broad to focused), pulse shape (symmetric biphasic to pseudo-monophasic), and pulse polarity (cathodic to anodic). An FNS was assessed, based on electrophysiological thresholds, in 204 electrically evoked compound action potential (eCAP) input/ output functions recorded from 33 ears of 26 guinea pigs. The stimulation level difference between auditory nerve eCAP threshold and FNS threshold was expressed a... View on Web
