In the pre-operative room, upper airway ultrasound measurements of the neck were obtained, namely, distance from skin to the hyoid bone, distance from skin to the thyroid isthmus and thickness of the base of the tongue. Clinical airway assessment details were noted from the pre-anaesthetic evaluation form. The airway management technique was noted. Receiver operating characteristic curves were used to assess the diagnostic value of these upper airway ultrasound measurements in predicting difficult airways.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The distance from the skin to the thyroid isthmus in the difficult airway group (0.37 \u00b1 0.133 cm) was significantly higher than in the non-difficult group (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.007).
