Bilateral choanal atresia is a congenital condition in which the back of the nasal passage is blocked, typically by abnormal bony or soft tissue formation. In cases of bilateral choanal atresia, the obstruction can lead to significant airway compromise, particularly in newborns and infants who are obligate nasal breathers. This obstruction prevents adequate airflow through the nasal passages, resulting in severe hypoxia and cyanosis, especially noticeable at rest when the infant is not able to compensate for the lack of airflow through their mouth.

The presence of cyanosis indicates a lack of adequate oxygenation, which is acute in situations where both nasal passages are blocked. Immediate intervention is often required to secure the airway, demonstrating the urgency of diagnosing and addressing this condition. The other options listed may cause respiratory distress or hypoxia but do not typically result in the pronounced cyanosis seen with bilateral choanal atresia.
