What is cormack lehane grading?

Cormack-Lehane grading is a system used to classify the view during laryngoscopy or intubation. It was first described in 1984 by Drs. Cormack and Lehane. The grading system is based on the visualization of the vocal cords during direct laryngoscopy.

There are four grades:

Grade I: Visualization of the vocal cords without any difficulty Grade II: Visualization of the vocal cords is possible after some manipulation of the laryngoscope Grade III: Visualization of only the epiglottis or only the inferior portion of the vocal cords Grade IV: No visibility of the vocal cords

This grading system is commonly used in anesthesia and emergency medicine to assess the likelihood of difficult intubation and to determine the appropriate course of action. A higher grade indicates a more challenging intubation.
