Trial Summary
What is the purpose of this trial?This trial is testing if stimulating a nerve in the ear with electricity during ear surgery can make the pupils get bigger.
Eligibility Criteria
This trial is for adults over 18 years old who are undergoing cochlear implantation or vagal nerve stimulator implantation and are willing to participate. It's not for those with a history of ear surgery, congenital malformations, pregnant/breastfeeding individuals, or anyone with certain medical conditions like heart arrhythmias, lung diseases, ulcers, dysautonomias, vasovagal syncope, or pre-existing hoarseness.Inclusion Criteria
I am over 18 and getting a vagal nerve stimulator implant.
I am over 18 and getting a cochlear implant.
I am scheduled for cochlear implant surgery.

Participant Groups
The study tests how the pupil dilates when Arnold's Nerve (part of the vagus nerve) is stimulated with an electrical device during routine cochlear implant surgery. The aim is to understand the connection between this stimulation and changes in pupil size.
