Preservation of residual hearing and improvement of speech performance through individualized placement of the Cochlea Implant electrode array

Introduction The goal of this prospective study is to safeguard remaining hearing capabilities and enhance speech outcomes through the personalized positioning of a cochlear implant (CI) electrode array. Preoperative computer tomography (CT) imaging and intraoperative ECochG monitoring determine this positioning. The study focuses on cochlear implant candidates who have pronounced hearing in the low frequency range. These individuals are implanted with a "SlimJ"-Electrode (Advanced Bionics), which is only partially inserted. This approach aims to mitigate insertion-related trauma and maintain the integrity of residual low-frequency hearing.
