Pupil dilation may reveal secrets of hearing nerve
NCT ID NCT05870527
First seen Feb 01, 2026 · Last updated Jun 23, 2026 · Updated 27 times
Summary
This study looks at how stimulating a nerve in the ear affects pupil size during cochlear implant surgery. Researchers will measure pupil dilation in 30 adults to learn more about the vagus nerve's role in hearing. The goal is to gather knowledge, not to treat hearing loss directly.

What this could lead to
If successful, this could help doctors better understand how the vagus nerve affects hearing, potentially improving cochlear implant outcomes.
What could go wrong
This is a very small, early study with only 30 participants, focused on measuring pupil size rather than treating hearing loss. It may not lead to any direct benefit for patients.
