Many aspects of the pharynx, larynx, and even trachea can be readily evaluated using ultrasound. The superficial nature of upper airway structures often enables precise anatomic visualization and dynamic assessment of physiology, including phonation and deglutition. The Upper Airway: Anatomy & Physiology Module begins with an overview of the role of ultrasound in the evaluation of the upper airway. A brief review of clinically relevant upper airway anatomy and physiology is provided. The sonographic appearance and dynamic physiology of the muscles, bone, cartilage, and mucosal surfaces of the upper airway are described in detail. Optimal transducer selection, patient positioning, and scanning techniques for sonographically evaluating the upper airway are discussed. The course concludes with imaging tips and pitfalls and a summary of salient teaching points.
