The three tiniest bones in your body are part of your middle ear. They bridge the gap across the top of your eustachian tube from your ear drum to the round window of your cochlea, and they not only transmit but also mechanically amplify the vibrations of your eardrum which represent the sound coming into your ears.

These bones (illustrated at the right) are commonly known as the hammer, anvil and stirrup, but their proper names are malleus, incus and stapes. As a set, they are called ossicles.

Some forms of hearing loss are caused by problems with these bones. When the hearing loss is caused by these bones, it's referred to as a conductive loss

Many times a conductive loss can be fixed or at least improved.
