The mammalian middle ear contains three ossicles (malleus, incus, and stapes), which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear.

Figure 3: X-Ray image of HOD presentation in 4-month-old Weimaraner puppy. Note "moth-eaten" appearance of metaphyses. Diagnosis relies on clinical signs and characteristic changes in radiographic images of the metaphyses. Bone changes can be observed on radiograph, and the disorder may progress to actual angular limb deformity.
The tympanic cavity and auditory tube develop from the first part of the pharyngeal pouch between the first two arches in an area which will also go on to develop the pharynx. This develops as a structure called the tubotympanic recess. [20] The ossicles (malleus, incus and stapes) normally appear during the first half of fetal development.
