What is the Hypoglossal Nerve?
The hypoglossal nerve, also known as cranial nerve XII or the 12th cranial nerve, is a motor nerve primarily responsible for controlling most tongue muscles, which is essential for tongue movements. This nerve is vital for functions like speech, swallowing, and chewing.
Key Characteristics:
- Origin: The hypoglossal nerve originates in the medulla oblongata, a section of the brainstem.
- Pathway: It exits the skull via the hypoglossal canal and extends to the tongue, innervating intrinsic and extrinsic tongue muscles.
-
Functions:
- Regulates tongue movements, including protrusion, retraction, and lateral motions.
- This is essential for clear speech and effective swallowing.
What Is Hypoglossal Nerve Stimulation?
Hypoglossal Nerve Stimulation (HGNS) is a treatment for obstructive sleep apnoea (OSA). It uses a surgically
implanted device that applies mild electrical stimulation to the hypoglossal nerve, which controls tongue movements,
to prevent the tongue from blocking the airway. This upper airway stimulation is synchronised with the patient's breathing
patterns to ensure uninterrupted airflow during sleep.
What Is Inspire Sleep Therapy?
Inspire Sleep Therapy is an FDA-approved treatment for obstructive sleep apnoea, offering a mask-free alternative to
traditional CPAP devices. This upper airway stimulation therapy involves a surgically implanted device that stimulates the hypoglossal nerve
to keep the airway open during sleep. It provides a more comfortable and discreet solution for those struggling with
CPAP machines, enhancing sleep quality without needing masks or hoses.
How Inspire Sleep Therapy Works
The Inspire Sleep implant consists of a small generator, a sensing lead, and a stimulation lead. Once implanted, the
device monitors breathing patterns during sleep. When it detects potential airway blockages, it delivers mild
stimulation to the hypoglossal nerves that control tongue and airway muscles. This stimulation keeps the airway
open, allowing for uninterrupted breathing and significantly reducing the occurrence of sleep apnoea episodes.
Is Inspire Sleep Therapy Right for You?
Based on FDA indications and insurance requirements, an Inspire-trained sleep doctor will determine if you meet the four criteria below:
- Diagnosed with moderate to severe obstructive sleep apnoea
- Struggle with or unable to get consistent benefit from CPAP
- Not significantly obese
- Over the age of 18
