Cormack–Lehane classification system

The Cormack–Lehane classification system is a method used in anesthesiology to categorize the view obtained during direct laryngoscopy, primarily assessing the visibility of the glottis and surrounding laryngeal structures. Introduced in 1984 by British anesthetists R.S. Cormack and J. Lehane, this system aids in predicting the difficulty of tracheal intubation.[1] In 1998, a modified version subdivided Grade 2 to enhance its predictive accuracy.[2]
