Iowa Cochlear Implant Clinical Research Center Study on Robotic-Assisted Versus Manual Electrode Array Insertion
Robotics-assisted electrode insertion overcomes many surgeon-related kinetic limitations such as insertion speed, tremor, drift, and lack of accurate force control. In human cadaveric cochleae, robotics-assisted electrode insertion causes less intracochlear trauma compared to manual insertion. Whether this technical advance results in functional benefits in CI patients remains unknown. To address this critical knowledge gap, the investigators will compare cochlear trauma assessed using CT scans, cochlear and AN function assessed using ECochG and/or the eCAP, and clinical outcomes quantified by postoperative residual acoustic hearing and speech perception scores between participants randomized to either manual or robotics-assisted electrode array insertion.
