[Early experiences with the Advanced Bionics cochlear implant].

Abstract

Introduction: The first cochlear implantation was performed in 1995 at the Department of Otorhinolaryngology and Head and Neck Surgery of the Albert Szent-Györgyi Medical School at the University of Szeged. On August 11, 2022, our clinic had the opportunity to insert the HiRes Ultra 3D implant, distributed by Advanced Bionics, a company that is less known in Hungary but internationally well-recognized. Objective: Currently, patients at our clinic are rehabilitated with devices from Cochlear Ltd. and MED-EL GmbH. To broaden this range of services, the first Advanced Bionics cochlear implantation surgery was performed at our clinic. Method: In our study, a HiRes Ultra 3D implant was implanted. During the operation, electrophysiological measurements (electrically evoked stapedius reflex threshold [ESRT], neural response telemetry [NRT], and impedance) were performed. The results were recorded using the Active Insertion Monitoring system. Hereinafter, we would like to review our initial experience. Results: The impedance thresholds were adequate, and both the neural response and the electrical stapedius reflex were responsible included . In accordance with the clinical protocol, after the immediate wound closure, the position of the electrode within the cochlea was also checked with low-dose fluoroscopic imaging. Discussion: Our short-term experience indicates that Advanced Bionics implant is fully suitable for serve sensorineural hearing loss. Conclusion: Based on our results, the implant offers the possibility of preserving residual hearing. From a surgical technique perspective, it provides a construction similar to the other two manufacturers’ current devices in the clinical portfolio. Orv Hetil. 2024; 165(45): 1772–1778.
