Two curves and three columns –A reappraisal of direct laryngoscopy

Airway management requires an assessment of the 2 curves of the airway and how these are affected by pathology within the head and neck region. The changes in airway curvature due to head and neck positioning as well as regional pathology are correlated with the effects of different airway devices to enable the operator to predict the success or failure of airway management. Airway device groups are not mutually exclusive to specific airway pathologies but may function successfully in a variety of scenarios.
