Question: 1 / 1185

Foreign body aspiration is more likely to obstruct which main bronchus?

Left main bronchus

Right main bronchus

The right main bronchus is more likely to be obstructed by foreign body aspiration due to its anatomical orientation. It is wider, shorter, and more vertically aligned compared to the left main bronchus. These features make it easier for aspirated objects to enter and lodge in the right bronchus.

In children, the incidence of foreign body aspiration also tends to favor the right bronchus for similar reasons. Objects that are inhaled typically follow the path of least resistance, and the anatomical structure of the right main bronchus facilitates this. Understanding these anatomical differences is crucial for emergency medicine as it influences diagnostic and management strategies in cases of suspected foreign body aspiration.
