Cormack-Lehane Grading
The Cormack-Lehane grading system classifies laryngeal view during direct laryngoscopy: Grade I (full glottis view), Grade II (partial view, subdivided into IIa and IIb), Grade III (only epiglottis visible), and Grade IV (no laryngeal structures visible). It guides real-time intubation decisions and future anaesthetic planning for trainees.
