Evaluation and comparison of conventional difficult airway parameters and ultrasound guided parameters in obese patients undergoing general anesthesia; a prospective observational study

Airway assessment using ultrasound has recently been proposed as simply, non invasive, bedside method as an  adjunct to clinical evaluation.

Our study is to evaluate and compare known conventional difficult airway parameters and ultrasound guided parameters in obese patients and obtaining best predictive method of difficult airway assessment.
