Several approaches have been undertaken over the last decade to preserve residual hearing. In
addition to surgical approaches (e.g., round window insertion, speed-of-insertion), device
modifications (electrode, e.g., shape/diameter of the electrode) and others (e.g., drugs, IOM) have
While the application of steroids in cochlear implantatology (e.g., Bento et al 2016, Skarczynski et al.
2018) has proven success, new, neuromodulatory approaches faile das yet in controlled, clinical
We therefore have investigated over the last few years in detail which surgical modification can
achieve the best result for preserving residual hearing.
Our model/animal/TB and live experiments looked deeply into the insertion of the CI electrode with
respect to atraumaticity (round window vs. cochleostomy approach), reducing intracochlear pressure
waves (opening technique for the RW, speed-of-insertion), sealing the cochlear opening and cable
positioning (e.g., artificial material, glue).
These results of different series will be summarized to guide the surgeon in their approaches of
improving cochlear implant service and actively promoting the preservation of residual hearing.
Bio: Arne Ernst, MD, PhD
Professor Arne Ernst is chairman of the Department of Otorhinolaryngology at UKB, Hospital of the University of Berlin, Charite Medical School and a pioneer of the cochlear implant program in Germany.
He specialises in otology, neurotology, vestibular rehab, and age-related audiovestibular disorders.
His clinical experience includes 250 papers in peer-reviews journals, 8 textbooks on audiology, otology, and neurotology. He has been principal investigator in five large multicentre and multinational studies on iinner ear pharmacology related to hearing loss, tinnitus, preservation of residual hearing in CI, and acute vertigo.
