Hypoglossal Nerve Stimulation in Patients With Obstructive Sleep Apnea

Hypoglossal nerve stimulation, or HGNS, emerges as an alternative therapy for patients with obstructive sleep apnea (OSA). It is a relatively new treatment option that can be used in patients who cannot tolerate continuous positive airway pressure (CPAP), or who have concentric collapse of the palate.

What Is HGNS?

HGNS is a sleep apnea treatment involving an implanted medical device developed by Inspire Medical Systems. As approved by the Food and Drug Administration (FDA) in 2014, HGNS stimulates the hypoglossal nerve in a rhythm synchronized with the breathing of patients with OSA.

HGNS electrical device implanted in the upper right chest that delivers pulses to the hypoglossal nerve. These pulses provide electrical stimulation to key muscles that assist with swallowing and breathing while sleeping.

Sleep Therapy Alternative

HGNS is recommended for sleepers who have failed or cannot tolerate treatment with positive airway pressure therapies, according to the FDA.
