OBJECTIVES: Cochlear implants (CIs) can restore hearing to individuals with severe deafness, yet clinical outcomes vary widely because it remains difficult to predict how electrical currents interact with the unique anatomy of each cochlea. A central challenge in auditory rehabilitation is the lack of experimental systems that capture both the anatomical fidelity and the electrical properties of the human cochlea....
3D-printed cochlear twins are a pre-competitive research tool at this stage; audiologists and CI surgeons should monitor this line of research as it may eventually support patient-specific electrode selection and surgical planning.
Patient-specific electrode placement is a key determinant of cochlear implant outcomes, and a validated physical simulation platform could reduce outcome variability and inform pre-surgical planning.
