This prospective observational study aims to evaluate the predictive value of thyromental height (TMH) and ultrasonographic airway measurements in predicting difficult airway in adult patients undergoing elective surgery under general anesthesia.
Preoperative airway assessment will include standard clinical evaluation, TMH measurement, and ultrasonographic measurements of anterior neck soft tissue. Perioperative airway management data, including intubation difficulty, number of attempts, and Cormack-Lehane classification, will be recorded.
The relationship between preoperative measurements and difficult airway will be analyzed to determine their predictive accuracy and clinical usefulness.
