Interventional procedure overview of daytime intraoral neuromuscular electrical tongue stimulation using a removable device for obstructive sleep apnoea

What the procedure involves
In this procedure, an intraoral removable device is used to deliver electrical stimulation to the intrinsic and extrinsic (genioglossus) muscles of the tongue. The aim is to improve tongue endurance and reduce airway obstruction during sleep.
A mouthpiece with an electrode array that fits onto the tongue is placed in the mouth by the patient during the daytime while they are awake. Bipolar biphasic current is then delivered for about 20 minutes with predetermined low frequency stimulation and rest periods. The mouthpiece is removed once the session is complete. The intensity of the stimulation is controlled by the patient, for example by using a smartphone app. An entire therapy usually lasts about 6 weeks, with a 20-minute daytime session each day while awake.
