Cochlear implants are used worldwide for the treatment of severe to profound bilateral sensorineural hearing loss in both adults and children. A number of implantees are likely to be treated with radiosurgery later in life, but very little is known about the effects of radiosurgery on cochlear implants. We report a cochlear-implanted patient who underwent radiosurgery due to a recurrent meningioma. After radiosurgery, the impedance of the implant maintained a normal range, and auditory performance tests were unchanged as compared to before radiosurgery. This is the first report addressing the effects of radiosurgery in a patient with a cochlear implant.
