Creation of a Cochlea Model with Integrated Electronics for Cochlear Implantation Training

Cochlear implantation is a vital procedure for patients with profound neurosensory hearing loss, offering the possibility of restored auditory perception and substantially improving their quality of life. However, the complexity of the surgery necessitates rigorous training for future otologic surgeons. This paper presents a novel, low-cost cochlea simulator that realistically emulates inner-ear anatomy and integrates reflective sensors, an Arduino Nano microcontroller, and an interactive display. The system allows trainees to practice electrode insertion techniques, measure insertion depth and speed, and receive immediate feedback on their performance. Our experimental results highlight the simulator’s reliability in monitoring electrode motion, accuracy in detecting backward movements, and ability to reinforce consistent insertion speeds. Furthermore, we provide an expanded analysis on the anatomy of the cochlea, the hearing process, and how these aspects informed our design. By bridging the gap between theoretical instruction and hands-on practice, this system supports a safer, more efficient training process for cochlear implantation. The study also discusses future directions, including enhancing the anatomical fidelity of the model and integrating advanced haptic feedback mechanisms to better emulate real surgical environments.
