title: Vocal cord adduction causing obstructive sleep apnea from vagal nerve stimulation: case report.
abstract: A recognized complication of vagal nerve stimulation is new or worsening sleep apnea. Its pathophysiology is not clearly understood. We report a patient with obstructive sleep apnea that was directly associated with vagal nerve stimulation causing recurring vocal cord adduction. Adjusting the stimulator settings resolved the problem.
