**Airway Assessment** is a procedure done to manage patient airway problems (Failure
to oxygenate, Failure to ventilate, failure to maintain a patent airway…).

 The prediction of difficult mask ventilation (DMV) is a challenging procedure, 
this is why the Ultrasound Scanner is a helpful tool in the prediction of these 
difficulties.

 Airway-related morbidity, as the result of an inability to anticipate difficult
airway, remains the primary concern for anesthesiologist.

 Because of high quality of imaging, non-invasiveness and relatively low cost, ultrasonography
has been utilized as a valuable adjunct to the clinical assessment of the airway

###  **Which ultrasound scanner is used for airway assessment?**

 The [SIFULTRAS-5.42](https://sifsof.com/product/double-head-wifi-color-ultrasound-scanner-sifultras-5-42-fda/)
is a reliable tool for the assessment of the subglottic airway. The advantages that
this Ultrasound offers is that requires minimal training, and doesn’t need patient
immobility or sedation.

 The newer models are compact and can be rapidly moved with ease from the pre-anesthesia
holding area to the operating room. This portability allows point-of-care use of
ultrasound US whenever and wherever it is needed. And practicality as it allows 
anesthesiologists to evaluate complex and varied anatomy.

Since many anesthesia providers had already acquired proficiency in US techniques
in US guided vascular access and regional nerve blocks, using US to evaluate the
airway could be learned and mastered without too much difficulty. Ultrasound of 
the upper airway may prove to become a useful adjunct to conventional clinical assessment
tools, as it has been successful in visualizing the relevant anatomy and critical
structures of the airway

This device allows the doctor to estimate the appropriate tracheostomy the size 
and length and avoid anterior neck structures as well as posterior tracheal wall
injuries.

 In the preoperative holding area sonographic assessment is done with the help of
a high-frequency linear probe. By placing the probe in the submandibular area in
the midline. Without changing the position of the probe, the linear array of the
US probe was rotated in the transverse planes from cephalad to caudal, until simultaneous
visualization of the epiglottis and posterior part of vocal folds with arytenoids
observed on the screen. Thereafter, following measurements are obtained with the
oblique-transverse US view of the airway .

Similarly, curved low-frequency (5 MHz) transducer is used to visualize the tongue
and shadows of the hyoid bone and mandible with the patient in the supine position.
The hyomental distances is measured from the upper border of the hyoid bone to the
lower border of the mentum in the neutral and extended head positions, respectively.

 Using ultrasound to help assess the difficult airway constitutes just yet another
valuable application of this versatile technology.
