The auditory ossicles are composed of the hammer bone, the anvil bone, and the stapes bone. The auditory ossicles are located in the middle ear drum chamber, is the smallest group of bones, mainly by the hammer bone, anvil bone, stirrup bone, these three independent bones are ligaments and joints connected to each other to form the auditory ossicles chain. The auditory ossicles are located between the tympanic membrane and the vestibular window, and their main role is to mediate sound waves to vibrate with each other. The auditory ossicles transmit sound from the outer ear to the inner ear through the principle of leverage, and at the same time amplify the sound waves to enlarge the range of hearing function. The order of these three parts of the auditory ossicles from the outside to the inside is that the hammer bone is connected to the anvil bone, and the anvil bone is connected to the stapes bone. The hammer bone is shaped like a hammer and is located in the middle and outermost part of the tympanic cavity. The stalk of the hammer bone is located between the mucous layer and the fibrous layer of the tympanic membrane. The body of the anvil bone is behind the upper tympanic chamber, connected with the head of the hammer bone to form the hammer-anvil joint, located between the hammer bone and the stapes. The stapes resembles a horseshoe, and the head of the stapes is connected to the long foot of the anvil. The stapes footplate is connected to the vestibular window by means of the annular ligament. The anatomy of the stapes can be visualized by CT or MRI of the temporal bone.
