MED-EL Podcast

In this episode, Dr. Peter Nopp is joined by Prof. Griet Mertens and Dr. Masoud Zoka Assadi to explore individualized cochlear implantation, from anatomy-based electrode selection to anatomy-based fitting. They also explain how OTOPLAN supports clinicians before and after surgery by visualizing the patient's unique cochlea, guiding electrode selection, and calculating frequencies tonotopically for a precise postoperative fitting.

In this episode, Marcus Schmidt is joined by Prof. Sumit Agrawal and Dr. Peter Nopp to explore how cochlear anatomy shapes cochlear implant design and performance. They discuss breakthrough synchrotron imaging, the variability in cochlear size and structure, and why deep insertion and full cochlear coverage matter for natural, rich sound.

In this first episode, Marcus Schmidt and Jennifer Robinson unpack what closest to natural hearing means, why it matters for cochlear implant users, and how MED-EL's unique technology is designed to replicate the way we naturally hear. Together, they explore the three pillars of closest to natural hearing that make this concept so powerful—and set our technology apart.
