ABSTRACT

Solid foreign bodies may be inhaled into the airway, something which is probably commonest in childhood but can occur at any age. Large foreign bodies may impact at the level of the vocal cords to cause severe and potentially fatal obstruction. Slightly smaller foreign bodies may pass between the cords and lodge in the trachea. Even smaller foreign bodies will pass into the lungs, generally down the right main bronchus, and become wedged in one of the smaller airways.
