In anesthesiology, the<unk> , also<unk>  classification, is used to predict the ease of intubation.  It is determined by looking at the anatomy of the oral cavity; specifically, it is based on the visibility of the base of uvula, faucial pillars (the arches in front of and behind the tonsils) and soft palate. Scoring may be done with or without phonation. Higher<unk>  (Class 4) is associated with more difficult intubation as well as a higher incidence of Sleep Apnea.
Scoring is as follows:
Class 1: Full visibility of tonsils, uvula and soft palate
Class 2: Visibility of hard and soft palate, upper portion of tonsils and uvula
Class 3: Soft and hard palate and base of the uvula are visible
Class 4: Only Hard Palate visible
