Cormack-Lehane Classification

The Cormack-Lehane Classification is a system used in medicine, specifically during intubation (placing a tube in the windpipe) to assess the visibility of the vocal cords. It has four grades: Grade 1 indicates full visibility of the cords, Grade 2 shows partial visibility, Grade 3 means only the epiglottis is visible, and Grade 4 means nothing is visible. This classification helps healthcare providers determine the difficulty of the intubation procedure, guiding their approach and ensuring patient safety during anesthesia or emergencies.
