Foreign bodies may be inhaled.
Infants and young children habitually
put objects into their mouths, and
these may be inhaled. Teeth may be
inhaled after a blow to the mouth or
during dental surgery. Such foreign
bodies may lodge in the larynx,
trachea or bronchi

13. Insertion
Foreign bodies are sometimes
inserted into any of the body orifices.
Infants and young children, for
example, may insert objects into the
nasal passages or an external
auditory meatus.
In these cases, radiography is
required only occasionally, since most
of these objects can be located and
removed without recourse to
radiography.

Many surgical procedures deliberately
introduce foreign bodies either in the
form of hemostatic clips (most
