Stylohyoid ligament

Dr Henry Knipe et al.

The stylohyoid ligament forms part of the styloid apparatus. The origin is at the styloid process of the temporal bone and it inserts into lesser horn of the hyoid bone.

The stylohyoid ligament provides part of the origin for the middle pharyngeal constrictor muscle and styloglossus muscle. It develops from the 2nd branchial arch 2, 4.
