Context: The scope of ultrasound is emerging in medical science, particularly outside traditional areas of radiology practice. Aims: We designed this study to evaluate feasibility of bedside sonography as a tool for airway assessment and to describe sonographic anatomy of airway. Settings and Design: A prospective, clinical study. Materials and Methods: We included 100 adult, healthy volunteers of either sex to undergo airway imaging systemically starting from floor of the mouth to the sternal notch in anterior aspect of neck by sonography. Results: We could visualize mandible and hyoid bone as a bright hyperechoic structure with hypoechoic acoustic shadow underneath. Epiglottis, thyroid cartilage, cricoid cartilage, and tracheal rings appeared hypoechoic. Vocal cords were visualized through thyroid cartilage. Interface between air and mucosa lining the airway produced a bright hyperechoic linear appearance. Artifacts created by intraluminal air prevented visualization of posterior pharynx, posterior commissure, and posterior wall of trachea. Conclusions: Ultrasound is safe, quick, noninvasive, repeatable, and bedside tool to assess the airway and can provide real-time dynamic images relevant for several aspects of airway management.
