Cochlear Implant Electrode Misplacement

Abstract

ochlear Implantation (CI) is an effective and doable alternative to restore hearing in cases of bilateral severe to profound hearing loss in patients who do not benefit from using an individual sound amplification device. 1,2 According to various authors by far the most common causes of recurrent CI is the migration of the implant and/or extrusion, technical failure and implant misplacement of the electrode array in the spiral canal of the cochlea. In general, the rate of complications is low. In the presence of abnormalities of the inner ear the risk of improper administration of the active electrode into the cochlea increases. 3 This complication according to some authors is 0.17-2.12%. 4
