Pupillary Dilation During Post-Auricular Vagal Nerve Stimulation

Single-Center Study of Pupillary Dilation During Post-Auricular Vagal Nerve Stimulation

• Status: Enrolling By Invitation
• Phase: N/A
• Study type: Interventional
• Enrollment: 30 (estimated)
• Sponsor: NYU Langone Health · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Not accepted

Summary

The research team will evaluate pupillary dilation from vagal nerve stimulation of Arnold's Nerve, a branch of the vagus nerve, during routine cochlear implantation surgery.

Detailed description

The objective of this study is to determine if electrical stimulation of Arnold's Nerve, a branch of the vagus nerve, can result in vagal nerve response through the measurement of pupillary dilation

Conditions

• Hearing Loss

Interventions

Type	Name	Description
DEVICE	Electrical stimulator	Electrical stimulation will be used to stimulate the Arnold's nerve and measure pupil dilation. The electrical stimulator is part of the standard facial nerve monitoring unit that we utilize in cochlear implantation and will be setup prior to surgery in standard fashion. The device allows for constant current stimulation, with stimulus range between 0-30 mA.
