Brief Summary
This prospective observational study aims to evaluate the relationship between preoperative ultrasonographic airway measurements and the Video-Intubation Difficulty Assessment Classification (VIDIAC) score in adult patients undergoing endotracheal intubation under general anesthesia. The study will investigate whether airway ultrasound parameters can predict difficult videolaryngoscopic intubation and assess their association with the Cormack-Lehane classification, intubation time, and other airway management outcomes.

Outcome Measures
Primary Outcomes (1)
To evaluate the relationship between preoperative ultrasonographic airway measurements and the VIDIAC score.
The relationship between preoperative ultrasonographic airway measurements and the Videolaryngoscopic Intubation and Difficult Airway Classification (VIDIAC) score will be evaluated in adult patients undergoing videolaryngoscopic intubation. The simplified VIDIAC score classifies patients as easy (-1 or 0), moderate (1), hard (2), or severe (≥3), with higher scores indicating greater videolaryngoscopic intubation difficulty. Correlations between ultrasonographic airway measurements and the VIDIAC score will be analyzed.
