Comparison of Different Scales for The Prediction of Difficult Airway

Although many tests exist for predicting a difficult airway, the search for a test with substantially higher specificity and sensitivity is still ongoing. The aim of this study is to evaluate the specificity and sensitivity of modified thyromental distance and modified sternomental distance measurements, scaled according to the patient's own three-finger breadth, in predicting difficult laryngoscopy and difficult tracheal intubation.
