Brief Summary
The hypothesis of this study is that ultrasound measurements may improve the preoperative detection of difficult laryngoscopy (DL) in pediatrics. The primary objective of this study will be to evaluate the usefulness for the prediction of a DL of five ultrasound measurements obtained from the neck skin to three structures of the upper airway (hyoid, epiglottis and anterior commissure of the vocal cords). Secondary objectives will include establishing, if possible, a cut-off point in these measurements; to compare these measures against the classic pre-intubation clinical screening tests.

Conditions
Outcome Measures
Primary Outcomes (1)
prediction of a Difficult laryngoscopy of five ultrasound measurements obtained from the neck skin to three structures of the upper airway (hyoid, epiglottis and anterior commissure of the vocal cords).
To evaluate the accuracy of five ultrasound measurements obtained from the neck skin to three structures of the upper airway (hyoid, epiglottis and anterior commissure of the vocal cords). Namely the DSH, DSE, DSG, DSH+DSE, and DSH-DSE in prediction of difficult laryngoscopy.
Preoperative
Secondary Outcomes (3)
The Modified Mallampati Score (MMS).
At Intubation
The thyromental distance (TMD)
preoperative
The upper lip bite test (ULBT)
Preoperative
Interventions
US measurements will be performed in the pre-operating room a , patients are placed in supine position with the head in a sniffing position on a surgical pillow and using the 15 MHz linear array transducer of the SonoSite™ S Series ultrasound in transverse position. A scan is made from the skin surface of the floor of the mouth to the trachea exerting the minimum possible pressure to identify the structures correctly.
