The stylohyoid ligament is a ligament that extends between the hyoid bone, and the temporal styloid process (of the temporal bone of the skull).

Anatomy

Attachments

It attaches at the lesser horn of hyoid bone^[1]^[2] inferiorly,^{[citation needed]} and (the apex of^[1]) the styloid process of the temporal bone^[1]^[2] superiorly.^{[citation needed]}

The ligament gives attachment to the superior-most fibres of the middle pharyngeal constrictor muscle.^[1]

Relations

The ligament is adjacent to the lateral wall of the oropharynx.^[1]

Inferiorly, it is adjacent to th hyoglossus.^[1]

Clinical significance

The stylohyoid ligament frequently contains a little cartilage in its center, which is sometimes partially ossified in Eagle syndrome.^[3]

Other animals

In many animals, the epihyal is a distinct bone in the centre of the stylohyoid ligament, which is similar to that seen in Eagle syndrome.^{[citation needed]}
