Fracture of hyoid bone

The hyoid bone is hoof-shaped, consisting of the hyoid bone body, large horns (2), and small horns (2), and is the main supporter of the tongue. The lower part is immediately adjacent to the thyroid cartilage, and the hyoid bone has a stem hyoid bone ligament connected to the styloid process of the temporal bone. The hyoid bone is mostly subcutaneous. The hyoid bone can be congenital malformations, and the stem hyoid bone ligament can be calcified or ossified to connect with the hyoid bone. Before normal people 20 to 30 years old, more than 50% of patients with hyoid bone and hyoid bone horn without bone connection. The hyoid bone is separated from the small angle of the hyoid bone by cartilage. The calcification of the stem hyoid bone ligament or osseointegration with the hyoid bone, or premature osteosynthesis, are all causes of fracture.
