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 score is assessed by asking the patient, in a sitting posture, to open their mouth and to protrude the tongue as much as possible. [1] 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.
Anatomical parts seen during laryngoscopy. Direct laryngoscopy is carried out (usually) with the patient lying on their back; the laryngoscope is inserted into the mouth on the right side and flipped to the left to trap and move the tongue out of the line of sight, and, depending on the type of blade used, inserted either anterior or posterior to the epiglottis and then lifted with an upwards ...
"The most useful modification is a subclassification of grade 3 into 3a when the epiglottis can be lifted from the posterior pharyngeal wall and 3b when it cannot be lifted." Indeed this is true, and in fact, it is more important whether the epiglottis can be lifted or not, rather than the vocal cords or arithenoids are fully seen (2a/2b)
Cormack shared the Nobel Prize in Physiology or Medicine in 1979 with Godfrey Hounsfield “for the development of computer assisted tomography.” [4] The book's title is inspired by the parable of six blind men and an elephant, in which the men, by approaching the animal from different angles, imagine it to be an elephant.
[77] [78] Furthermore, one study of experienced anesthesiologists, on the widely used Cormack–Lehane classification system, found they did not score the same patients consistently over time, and that only 25% could correctly define all four grades of the widely used Cormack–Lehane classification system.
