Summary

The aim of this observational study is to evaluate the accuracy of the HMDR combined with the ULBT as a predictor of difficult laryngoscopy in obese patients undergoing elective surgery under general anesthesia, regarding:

* Correlation of HMDR-ULBT values with Cormack-Lehane grades during laryngoscopy.
* Comparison of HMDR-ULBT with standard HMDR in predicting difficult laryngoscopy.

Conditions

  • Airway Assessment

Interventions

DIAGNOSTIC_TEST

Hyomental distance measured using ultrasound in neutral head position, maximum head extension and during upper lip bite test

Hyomental distance will be measured using ultrasound in three positions: neutral head position, maximum head extension, and during the upper lip bite test (ULBT).
