An increase in auditory stimulation levels may stem from a decrease in auditory-nerve excitability due to overstimulation. A break would allow recovery of excitability, leading to lower current use and less cross-stimulation of the facial nerve. Break duration ranged between 1 week to several months.  \nMain outcome measures: Lower and upper electrical stimulation levels required for hearing (N = 3), reported or observed FNS (N = 4), and FNS thresholds (N = 1) before and after the break.  \nResults: In all cases for whom stimulation levels for hearing were measured both before and after a break (Patients 1 to 3), these decreased after the break. In 2 of these cases, the decreased stimulation levels helped to manage persistent FNS. In one other case (Patient 4), FNS thresholds decreased slightly or remained unchanged after the break and the stimulation of most electrodes continued to lead to FNS with no change in auditory perception.  \nConclusions: A break from CI stimulation could be considered to manage persistent FNS when auditory stimulation levels increase over time. In some cases, a break may reduce the stimulation levels required for hearing, minimizing or eliminating the occurrence of FNS. Further research is needed to determine the biological mechanisms involved, optimize the duration of the break, as well as determine its long-term effectiveness.  \nKeywords: Cochlear implants, Facial nerve stimulation, Nonauditory stimulation, Overstimulation  \nIntroduction  \nElectrical stimulation may induce facial movements (usually eyelid and/or lip) due to the spread of the intracochlear current injected by  \naCambridge University Hospitals, Emmeline Centre for Hearing Implants, Cambridge, UK, bCambridge Hearing Group, Cambridge, UK, cSOUND Lab, Department of Clinical Neurosciences, University of Cambridge, Cambridge, UK, dMRC Cognition & Brain Sciences Unit, University of Cambridge, Cambridge, UK and eSENSE Lab, Department of Clinical Neurosciences, University of Cambridge, Cambridge, UK  \nThe authors disclose no conflicts of interest.  \n*Corresponding author.
