Mallampati score
The Mallampati score, or Mallampati classification, named after the Indian anaesthesiologist Seshagiri Mallampati, is used to predict the ease of endotracheal intubation. 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 work. It is an indirect way of assessing how difficult an intubation will be; this is more definitively scored using the Cormack–Lehane classification system, which describes what is actually seen using direct laryngoscopy during the intubation process itself. A high Mallampati score (class 3 or 4) is associated with more difficult intubation as well as a higher incidence of sleep apnea.
The score is assessed by asking the patient, in a sitting posture, to open their mouth and to protrude the tongue as much as possible. The anatomy of the oral cavity is visualized; specifically, the assessor notes whether the base of the uvula, faucial pillars (the arches in front of and behind the tonsils) and soft palate are visible. Scoring is generally done without phonation. Depending on whether the tongue is maximally protruded and/or the patient asked to phonate, the scoring may vary.
Modified Mallampati Scoring:
Original Mallampati Scoring:
Posture
The assessment can be performed with the patient in both a sitting or supine position. With tongue maximally protruded, assessment in the either position has not been found to significantly change the provider's view and has been shown to change the predictive value of the Mallampati Scoring. It is, however, important to standardize the approach for airway trainees to limit any possible variation.
Phonation
Phonation during the assessment includes the patient making an "Ah" sound with mouth open and tongue maximally protruded in either sitting or supine position. This action leads elevation of the soft palate, therefore, improving the Mallampati classification grade. Phonation has been shown to improve Mallampati classes III and IV to I and II in majority of assessments. Studies found that these improvements identified falsely classified difficult airways in most cases but have also falsely masked difficult airways in minority of cases. Given the morbidity and mortality associated with difficult airways, it is important to standardize the approach for airway trainees, and larger studies are needed to conclude whether phonation improves the predictive value of Mallampati scoring.
