What is cormack-lehane?

The Cormack-Lehane classification is a system used to grade the view of the larynx during direct laryngoscopy. The classification was developed by Drs. Robert Cormack and John Lehane in 1984 to provide a standardized way to describe the quality of the view of the vocal cords during intubation. The classification ranges from grade 1 to grade 4, with grade 1 indicating an unobstructed view of the vocal cords and grade 4 indicating complete obstruction of the airway. This classification system is widely used by anesthesiologists to assess the difficulty of intubation and plan for appropriate airway management.
