Atresia can be diagnosed prenatally based on ultrasound by identifying signs of congenital high airway obstruction syndrome (CHAOS). Patients with an advanced airway obstruction and inspiratory stridor at rest comprise some of the most feared and complicated cases for the anesthesiologist. 33 The incidence of difficult mask ventilation and impossible mask ventilation among patients with severe stridor and upper airway obstruction of more than 75% of the lumen reaches 40% and Advantages associated with subglottic jetting include minimal movement of the vocal cords, expulsion of blood or tissue debris from the trachea during expiration, 2,8,51 and excellent surgical access to the larynx and subglottis.
