The '''Mallampati score''' is a classification system used to predict the ease of [[endotracheal intubation]] based upon the anatomical structures visible during examination. A Mallampati score of 3 or 4 is associated with increased risk for difficult intubation.<ref name=":0">{{Cite journal|last=Mallampati|first=S. R.|last2=Gatt|first2=S. P.|last3=Gugino|first3=L.

==Technique==
The Mallampati score is assessed while the patient is sitting in an upright position with an open mouth and attempting to protrude the tongue as much as possible without phonation.<ref name=":0" /> The score may vary considerably if the patient is not attempting maximal tongue extrusion or is phonating.
