In this MRI image, the tongue is being sucked into the back of the throat as the person sleeps. This partially blocks the airway, creating obstructive sleep apnoea (OSA), which also causes snoring.		This MRI image shows the aveoTSD holding the tongue gently forward, preventing it falling back. Note how the airway is now open & clear. This stops, or greatly reduces snoring, and also treats obstructive sleep apnoea (OSA).
