Fusion of the ear bones

 

Fusion of the ear bones is the joining of the 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.

Related topics include:

  • Chronic ear infection
  • Otosclerosis
  • Middle ear malformations
