episodes and daytime
somnolence, as well
as physical character-
istics such as BMI and
neck circumference,

Because there is "no single reliable predictor of difficult airway,"
you also should take into account other "routinely used indicators of

neck movement and limited thyromental distance," says Girish P.
Joshi, MBBS, MD, FFARCSI, a professor of anesthesiology and pain
