Mallampati Scale

A clinical instrument used to assess the ease of obtaining an airway
Class I Visualization of the soft palate, fauces, uvula, and both anterior and posterior pillars
Class II Visualization of the soft palate, fauces, and uvula
Class III Visualization of the soft palate and the base of the uvula
Class IV (difficult) The soft palate is not visible at all

The Mallampati scale ranges from class 1, where all oropharyngeal structures are visible to class 4, with the soft palate not visible in a patient sitting upright with mouth maximally open and tongue protruded (14).
Although the Mallampati scale is related to intubation prognosis (p=0.003), it did not seem to respond well to intubation, given that there were cases where the scale recorded was 1-2 and yet intubation was difficult and vice versa.
The intubation condition according to the Mallampati scale was assessed as class 4, and she displayed normal neck mobility.

(6) Classifications of 3 or 4 on the Mallampati scale should be referred out for a polysomnography test.
The Mallampati scale can also be used to quantify degrees of oropharyngeal narrowing.
