At what age does the hyoid bone calcify?
At what age does the hyoid bone calcify?
Ossification of the hyoid was seen only after 30 weeks’ gestation. The body of the hyoid was ossified in all infants older than 4 months, and the greater cornua were ossified in all those older than 6 months. Ossification of the lesser cornua did not appear in children less than 15 years of age.
What causes hyoid bone syndrome?
It is thought to result from tendinitis or tendinosis of the muscles that insert onto the hyoid bone. One study found focal degenerative changes of the middle constrictor muscle where it insert on the hyoid bone. There may also be calcification of the stylohyoid ligament that inserts onto the hyoid bone.
What is hyoid syndrome?

Is the hyoid flexible?
In children and adolescents (in whom the hyoid bone is still flexible because ossification is yet to be completed) fracture may not occur even after serious trauma.
What does the hyoid bone look like?
The hyoid bone (hyoid) is a small U-shaped (horseshoe-shaped) solitary bone, situated in the midline of the neck anteriorly at the base of the mandible and posteriorly at the fourth cervical vertebra. Its anatomical position is just superior to the thyroid cartilage.
Why is the hyoid bone important in understanding the development of language in early hominins?
The hyoid bone is crucial for speaking as it supports the root of the tongue. In non-human primates, it is not placed in the right position to vocalise like humans.
Can I feel my hyoid bone?
The hyoid bone is a slender, U-shaped bone. It’s suspended just beneath the mandible. It isn’t directly attached to any other bone. You can feel your own hyoid bone here, and you can move it from side to side.
