While Mallampati classes I and II are associated with relatively easy intubation, classes III and IV are associated with increased difficulty. A systematic review of 42 studies, with 34,513 participants, found that the modified Mallampati score is a good predictor of difficult direct laryngoscopy and intubation, but poor at predicting difficult ...
The Cormack–Lehane system classifies views obtained by direct laryngoscopy based on the structures seen. It was initially described by R.S. Cormack and J. Lehane in 1984 as a way of simulating potential scenarios that trainee anaesthetists might face. [1] A modified version that subdivided Grade 2 was initially described in 1998. [2]
The Mallampati score is drawn from the observation that the size of the base of the tongue influences the difficulty of intubation. It is determined by looking at the anatomy of the mouth, and in particular the visibility of the base of palatine uvula, faucial pillars and the soft palate. Although such medical scoring systems may aid in the ...
Mallampati score. One of seven parameters used to calculate a SARI score. The Simplified Airway Risk Index (SARI), or El-Ganzouri Risk Index (EGRI), is a multivariate risk score thought to estimate the risk of difficult tracheal intubation. The SARI score ranges from 0 to 12 points, where a higher number of points indicates a more difficult airway.
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 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 ...
