the aim of this study was to evaluate the accuracy of different ultrasonographic parameters and clinical tests to predict difficult airway assessment. Ultrasonographic parameters were: hyo-mental distence, tongue width, skin to epiglottis distence and skin to hyoid bone distence. these parameters were recorded and their predictive acurracy was studied.

This study analyzed a sample size of 200 patients undergoing elective or urgent surgery under general anesthesia and recieving neuromuscular blocking agent before laryngoscopy. the correlation between ultrasonographic parameters and difficult laryngoscopy was studied
