For adults and children who experience aberrant facial nerve stimulation (AFNS) after undergoing unilateral or bilateral cochlear implantation (CI), reprogramming the CI device was found to decrease stimulation to the facial nerve. Reprogramming strategies included raising the pulse width or increasing the interphase gaps. For individuals whose AFNS did not resolve with these strategies, decreasing the current of offending electrodes was programmed just below the facial nerve stimulus level. Individuals with single channel arrays who required a decrease in current experienced significantly affected auditory outcomes.
