Upper airway is a complex anatomic structure. Anticipating, preparing, and managing a difficult airway is crucial in operating rooms and intensive care units (ICU). Difficult airway management is the most essential skill among anesthesiologists and critical care physicians. Airway ultrasound (AWUS) has become an inherent part of the armamentarium for managing difficult airway. AWUS is utilized for understanding sonoanatomy of the upper airway, anticipating difficult airway prior to intubation, helping in real-time monitoring of the intubation process, screening prior to airway procedures, and preextubation airway assessment. AWUS has added a new bedside dimension to difficult airway management, performing airway procedures with great accuracy in detecting and troubleshooting complications promptly.
