Study Overview
Brief Summary
This study aims to evaluate the utility of preoperative airway ultrasonography in predicting difficult airway in adult patients undergoing elective surgery under general anesthesia. Ultrasound measurements of airway structures—including tongue thickness, anterior neck soft tissue, and distance from skin to epiglottis—will be performed preoperatively and correlated with conventional airway assessment scores and laryngoscopic view during intubation. The study seeks to determine whether ultrasound parameters improve the accuracy of difficult airway prediction compared to standard clinical assessment.

- Observational
Eligibility Criteria
- Ages
- 18.00 Year(s) to 70.00 Year(s) (—)
- Sex
- All
Inclusion Criteria
- •All adult patients aged 18 years and above, classified as ASA physical status I–III, scheduled for elective surgeries under general anesthesia, will be evaluated preoperatively.
- •Written informed consent will be obtained from all participants.
- •Exclusion criteria include known difficult airway requiring awake intubation, facial or neck deformities, emergency surgeries, or refusal to consent.
- •Standard demographic and clinical data, including age, sex, BMI, comorbidities, and previous anesthesia history, will be recorded.
- •In addition, preoperative airway ultrasonography will measure key anatomical parameters such as tongue thickness, anterior neck soft tissue, and distance from skin to epiglottis.
- •These ultrasound findings will be correlated with laryngoscopic view and intubation difficulty (Cormack-Lehane grade) to assess whether ultrasonography improves prediction of difficult airway compared to standard clinical assessment.
Exclusion Criteria
- •Patients with expected difficult airway Previously confirmed difficult airway MPG 3 & 4 ASA 4 Pregnancy.
