The Mallampati Scale is a simple but effective test to assess your patient’s (or your own) airway .

The subject should be sitting or standing with their head on a 90 degree axis to the floor. They protrude their tongue (not necessary to say “ahh”) and with a direct light into the  mouth, look in and/ or take a picture.
Class III or IV conditions are certain candidates for further testing and possible therapy.
The tongue is the most common factor in Obstructive Sleep Apnea.
Now that you learned this you will probably be heading for a mirror. How did you rate?
