Nerve to stapedius

The nerve to stapedius arises from the facial nerve to supply the stapedius muscle. The branch is given off in the facial nerve's mastoid segment, as it passes posterior to the pyramidal process.

Damage to this branch with resulting paralysis of stapedius leads to hypersensitivity to loud noises (hyperacusis).
