Abstract Purpose of Review Clinical application of ultrasound (US) in airway management has continued to expand and evolve over the years. Our narrative aims to provide an updated summary of the role of airway US in current anesthesia practice, based on evidence published in the recent 5 years. Recent Findings Evidence continues to support the use of US in identifying the cricothyroid membrane and tracheal interspace for infraglottic airway access. While US shows potential in improving the accuracy of prediction of difficult airways, no standardized scanning protocol has yet to be created. Other promising clinical applications of airway ultrasound include confirmation of tracheal intubation, choosing of appropriate endotracheal tubes, assessment of vocal cord function, and guiding of upper airway blocks. Summary Ultrasound has numerous advantages: quick, easy to use, accessible, non-invasive, low radiation exposure; and it provides both dynamic and static images with good inter-operator reliability. Improvement in technology has aided the continuous evolution and expansion of the use of US in airway management. Airway US training should be incorporated into the education curriculum of personnel involved in airway management. Keywords Ultrasound . Ultrasonography . Airway . Cricothyroid membrane .

Introduction The ultrasound (US) machine has become ubiquitous thanks to its portability and simplicity. Its use as a bedside imaging tool has found its way into numerous medical fields, and airway management is no exception. A non-invasive, point-ofcare ultrasound (POCUS) assessment of the airway can be rapidly obtained to guide clinical management. Our narrative aims to provide an updated summary of the role of airway

ultrasound in current anesthesia practice, based on evidence published in the recent 5 years.
Basic Principles in Airway Ultrasound A standard high-frequency linear probe (6–13 MHz) with the US machine set to “small parts/musculoskeletal” provides optimal resolution of the upper airway structures in adults. The concept of the tissue-air border is crucial in airway US [1]. The border shows up as a bright white line as the US beams reach air. As air blocks transmission of US beams, structures behind the tissue-air border cannot be interpreted. The clinical significance of this is that we can only visualize th
