Group	Intervention	Description
obese patient	obese patients	BMI\>30 kg/m2 and underwent bariatric surgery

Primary Outcome Measures

Name	Time	Method
airway evaluation for menagement in obese patient	3 year	preoperative airway measurements routinely performed (mallampati score, thyromental distance, neck circumference ..)for each patient will be evaluated
thyromental distance	3 year	TMD was measured as straight distance between thyroid notch and lower border of mental prominence.(cm)
neck circumference	3 year	Neck Circumference was measured in the midway of the neck, between mid-cervical spine and mid anterior neck, to within 1 mm, using non-stretchable plastic tape with the subjects standing upright.
mallampati score	3 year	Class I : Visualization of the soft palate, fauces; uvula, anterior and the posterior pillars. Class II : Visualization of the soft palate, fauces and uvula. Class III : Visualization of soft palate and base of uvula. Class IV: Only hard palate is visible. Soft palate is not visible at all.
