If you've ever had even a basic checkup at the doctor, you've had an otoscope stuck in your ear — it's what your doctor uses to examine the inside of your ear.
Being examined with an otoscope is completely painless, but it can feel a little strange. This instrument has a magnifying lens and a small light that allows your doctor to see parts of your ear canal that would otherwise be hidden. Occasionally, this tool is also called an auriscope. Otoscope has Greek roots, oto from ous, "ear," and scope, from skopein, "to look at."
