Pupil changes during vagus nerve stimulation during ear surgery
Part of Brain & nervous system, Ear, nose & throat clinical trials.
This study looks at how your pupils (the black center of the eye) respond while a vagus nerve device is turned on during surgery for either a cochlear implant or a vagus nerve stimulator. It aims to better understand the eye/nerve effects of this stimulation, which may improve how such procedures are done safely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 18 or older and can agree to join the study
- You are scheduled for cochlear implant surgery or an implantable vagus nerve stimulator surgery
- You do not have a past ear surgery that would count as prior ear surgery for the study (and no prior cochlear implant)
- You are not pregnant or breastfeeding
- You do not have certain health issues that affect the vagus nerve or safety of stimulation, like heart rhythm problems or lung disease

This study records how the hearing nerve responds to speech sounds during planned brain surgery. It aims to understand hearing loss better and may help improve future treatments.
This trial tests if stimulating a nerve in your ear (vagus nerve) before and after noncardiac surgery can improve your recovery. It's for adults aged 18 to 84 having planned or time-sensitive surgery lasting at least 2 hours.
This study tests a gentle ear nerve stimulation to see if it can help manage pain after minimally invasive chest surgery (VATS). It might reduce the need for pain medicine and improve your recovery.
This study tests a new way to stimulate your hearing nerve during ear surgery while you are awake. It might help doctors better understand hearing loss and improve future treatments.
This study tests a gentle ear stimulation device that may help prevent confusion and improve mood after heart surgery. It is a safe, non-drug approach that could help you recover more smoothly.
This trial tests if a gentle electrical stimulation on the ear can help prevent postoperative delirium (sudden confusion) in older patients after surgery. It focuses on people 65 and older who will have longer operations.
