In anesthesia, the Mallampati score or Mallampati classification, named after the Indian anaesthesiologist Seshagiri Mallampati, is used to predict the ease of endotracheal intubation. [1] The test comprises a visual assessment of the distance from the tongue base to the roof of the mouth, and therefore the amount of space in which there is to ...
Mallampati score: Class I and II of the modified mallampati scoring results in 0 points whereas a class III is given 1 point and a class IV 2 points. Movement of the neck: The ability to move the neck more than 90 degrees results in 0 points whereas a movement range of 80-90 degrees results in 1 point and a movement range below 80 degrees ...
In 1983, Mallampati published a letter describing a difficult intubation in a female patient whose mouth could open widely but whose tongue obstructed view of the faucial pillars and uvula. [2] He hypothesised that the size of the tongue was a significant factor in predicting difficult laryngoscope usage since a large tongue would likely ...

Common methods of assessing difficult airways include a Mallampati score, Cormack-Lehane classification, thyromental distance, degree of mouth opening, neck range of motion, body habitus, and malocclusion (underbite or overbite). A recent Cochrane systematic review examines the sensitivity and specificity of the various bedside tests commonly ...
In statistics, a k-th percentile, also known as percentile score or centile, is a score below which a given percentage k of scores in its frequency distribution falls ("exclusive" definition) or a score at or below which a given percentage falls ("inclusive" definition); i.e. a score in the k-th percentile would be above approximately k% of all scores in its set.
Thyromental distance (TMD) measurement is a method commonly used to predict the difficulty of intubation [1] and is measured from the thyroid notch to the tip of the jaw with the head extended. [2]
The figure illustrates the percentile rank computation and shows how the 0.5 × F term in the formula ensures that the percentile rank reflects a percentage of scores less than the specified score. For example, for the 10 scores shown in the figure, 60% of them are below a score of 4 (five less than 4 and half of the two equal to 4) and 95% are ...
