Cochlear implantation (CI) can restore the hearing and improve the speech perception of patients with severe and profound hearing loss, but there are other important aspects of hearing to restore. Music, among these, is a very important art form that can evoke strong emotions and has a considerable impact on the quality of life of CI recipients . However, it is well known that music perception is limited in CI with totally electric hearing as a result of limited spectral sensitivity and slow varying temporal envelopes.
this presentation will be about the music perception abilities in CI users comparing prelingual recipients with postlinguals, CI users with normals on different aspects of music appreciation
Research and clinical interest in cochlear implant (CI) electrode impedance have evolved significantly throughout 2024 and 2025. The current focus has shifted from simple "functionality checks" to using impedance as a sophisticated biomarker for the internal environment of the cochlea. In cis, electrode impedance measurement plays a role in optimizing power requirements, establishing electrode integrity, and determining electrical stimulation parameters such as the pulse duration, pulse amplitude, and stimulation rate. any changes in impedance levels may indicate issues with the electrodes and/or cochlear implants, such as short circuits, open circuits, or damaged devices. Long-term use of the device may lead to a reduction in its efficiency in delivering electrical current to the surrounding cochlear tissues, resulting in an increase in impedance and decreased implant effectiveness. Therefore, it is saliently important to perform follow-up examinations post-implantation to investigate potential changes in the electrical impedance of cochlear implants over time. On the other hand, early activation results in decrease of impedance and better voltage transmission across electrodes. This of course will improve the outcome performance of CI. Impedance voltage matrix an emerging tool provide a deeper insight on the electrode neural interface at each electrode. Different electrode impedance models are developing to be integrated into clinical practice using the standard software. All detailed related updates will be highlighted in the roundtable.
