Hair tourniquet of the circumvallate papillae: a potentially "hairy" situation.

Oral foreign bodies and hair-thread tourniquets are fairly common findings. The combination of the two, however, is rarer.

We discuss methods for removal of hair-thread tourniquets as well as techniques for examining children for oral foreign bodies.
