	*Used to treat refractory [[epilepsy]]
	*Pulse generator implanted in chest, electric lead attached to vagus nerve in neck
	*Generator stimulates vagal nerve at regular intervals
	**Usually does NOT stimulate right vagus nerve (which innervates heart)
	*Magnet over VNS leads to extra stimulation
	**Patients/caregivers may use magnet in case of aura or breakthrough seizure

	~~==Complications==~~

	*Hoarseness, [[cough]], [[sore throat]]
	*Drooling, dysphagia
	*Torticolis/neck spasms
	*Anorexia
	*Shoulder abduction
	*[[Urinary retention]]
	*Outbursts of laughter

	*Superficial [[skin infection]]
	*Deep space infection (e.g. [[retropharyngeal abscess]], [[Ludwig's angina]]
	*Vocal cord paralysis
	*Contraction of supraglottic structures--> [[stridor]], sleep apnea
	*Facial muscle paresis
	*Cardiac [[arrhythmia]] (rare, as usually left vagus is stimulated)
	*Lead fracture
	**[[Twiddler's syndrome]]: repeated (often subconscious) manipulation of device, can lead to lead fracture or other device malfunction
