Evaluation of Multi-Slice Computed Tomography in Assessment of Cochlear Implant Electrode Position: A Pictorial Essay

Fatemeh Nasri, Hashem Sharifian, Mehrzad Mehdizadeh and Mohammad Pir Hayati

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 the electrode position on clinical results following cochlear implant surgery, in this study we also compared the findings on the electrode location with the results of audiometry of children after one year of follow up. Finding the best location for the electrode results in better audiometric outcomes.
