Summary

This study was designed to assess the success of indirect laryngoscopy and ultrasonographic measurements in the prediction of difficult airway. All patients were examined by indirect laryngoscopy and ultrasonography preoperatively and the predictive values for difficult airway of these methods were compared.

Detailed description

Difficult airway is a condition that increases the patient's vital risk and leaves the anesthesia and surgical team in a difficult position. Failure to perform an adequate preoperative evaluation may result in the team being unprepared. Therefore, various methods have been investigated in the prediction of difficult airway from past to present. With the development of technology, imaging methods have become routine applications in clinical use. Ultrasonography and indirect laryngoscopy have been shown to be used in predicting difficult airway in the literature, but there is no study showing which is a better predictor.

Conditions

• Difficult Intubation

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Ultrasonographic upper airway measurements	Ultrasonographic upper airway measurements: Epiglottis-skin distance, Hyoid bone-skin distance, Anterior commissure-skin distance and Thickness of tounge root. Indirect Laryngoscopy: Grading of laryngoscopic view (I=Visible anterior commissure and vocal cords, II= visible posterior part of vocal cords and posterior commissure, III= Visible posterior commissure and epiglottis, IV= Visible only epiglottis tip and posterior pharyngeal wall)
