Electrode selection for hearing preservation in cochlear implantation: A review of the evidence

Although there is some evidence that indicates that shorter electrodes may improve both short and long-term hearing preservation rates in cochlear implant patients, no study has directly compared implant length on hearing preservation in a similar patient population. A randomized trial of short and standard length electrodes for hearing preservation is warranted. In the interim, utilization of current electrodes measuring 20-25 mm could seem to be a prudent approach when seeking to preserve residual hearing without unduly compromising cochlear coverage.
