Laryngopharyngeal Dysfunction From the Implant Vagal Nerve Stimulator

Abstract

Patients in whom a vagal nerve stimulator is placed can have adverse side effects. These can be related to the surgical manipulation of the vagus nerve, resulting in a temporary paresis of the vocal folds. A second set of side effects is related to the actual electrical stimulation of the device, and these side effects can directly affect the laryngeal musculature.
