| The air pressure on either side of the eardrum is normally kept equal for proper functioning of the middle ear structures, namely the malleus, incus and stapes bones. |
| The malleus, or hammer, is the largest of the three ossicles. |
| In anatomy the term anvil is applied to one of the bones of the middle ear, the incus, which is articulated with the malleus. |
| In such cases, the malleus head and the incus body remain fixed together but the entire bloc is displaced. |
| This handpiece is specially recommended for canalplasty, ossiculoplasty and incus and malleus stapedotomy. |
| These are the malleus, or hammer, the incus, or anvil, and the stapes, or stirrup. |
