Cochlear implant has become the standard therapy to rehabilitate patients with severe to profound bilateral sensorineural hearing loss. The position of the electrode in the scala and the depth of its insertion have been shown to be predicting factors of hearing outcomes. This article serves to review the multi-slice computed tomography imaging characteristics and appearance of cochlear implant, their exact position and the depth of insertion in children who underwent cochlear implant surgery. Moreover, in order to evaluate the impact of electrode position on clinical results following the cochlear implant surgery, in this study we also compared the findings about the electrode location with the results of audiometry of children after one year of follow up to find the best location of the electrode, which results in better audiometric outcomes.
