The stapedius muscle contracts in response to sound, causing a stiffening of the ossicular chain. The increase in stiffness may be detected by measuring the resistance of the ossicular chain to sound transmission.

The stapedial reflex is absent in:

  • otosclerosis
  • scarring of the middle ear from otitis media
