Fusion of the ear bones
Fusion of the ear bones is an abnormal joining of the three bones of the middle ear. These are the incus, malleus, and stapes bones. Fusion or fixation of the bones leads to hearing loss, because the bones are not moving and vibrating in reaction to sound waves.

The ear consists of external, middle, and inner structures. The eardrum and the three tiny bones conduct sound from the eardrum to the cochlea.
The external structures of the ear may aid in diagnosing some conditions by the presence or absence of normal landmarks and abnormal features including earlobe creases, preauricular pits, and preauricular tags.
