Data are presented as means ± standard deviations (range) or the numbers of patients. Group A: the patients were intubated with the Airtraq laryngoscope; Group G: the patients were intubated with the GlideScope. TMD = thyromental distance; A-OJM = atlanto-occipital joint movement; ULBT = upper lip bite test, A: lower incisors can bite the upper lip above the vermilion line; B: lower incisors can bite the upper lip below the vermillion line; C: lower incisors cannot bite the upper lip [16].
