We aim to identify anatomical factors that affect upper esophageal occlusion during the application of paratracheal pressure.
Measure the sternomental distance, thyromental distance, neck length, neck circumference, Mallampati score, BMI, Neck motion, inter-incisor gap, thyrosternal distance. And analysis these factors are associated with upper esophageal occlusion or not.
