The tumor was encountered in the mastoid antrum adjacent to the incus. The tiniest mammalian bones--the middle ear's sound-transducing trio of the stapes, incus, and malleus--most distinctively distinguish mammals from other vertebrates. The eardrum vibrates and transmits sound waves to the ossicles (three tiny bones--malleus, incus, and stapes) that amplify the waves, transporting them into the fluid-filled cochlea. |
