The Narval Appliance

The Narval CC™ retains the mandible – lower jaw – in a forward position which brings forward the base of the tongue and increases the space behind the tongue.

This has a double impact:

 

  • It reduces the risk of obstruction or collapse of the airway, and decreases the frequency of apnoeas or hypopnoea which lead to sleep fragmentation.
  • The speed at which the air is inhaled decreases, reducing the snoring that is caused by the vibration of soft tissues in the throat.
