The hyoid bone (lingual bone or tongue-bone) (/ ˈ h aɪ ɔɪ d / [2] [3]) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra .
The hyoid bone fracture is a very rare fracture of the hyoid bone, accounting for 0.002% of all fractures in humans. It is commonly associated with strangulation and rarely occurs in isolation. The fracture may be associated with gunshot injury, car accidents or induced vomiting. In 50% of strangulations and 27% of hangings, hyoid fractures occur.
It originates from the hyoid bone; it inserts onto the side of the tongue. It is innervated by the hypoglossal nerve (cranial nerve XII). It acts to depress and ...
The entire superior edge of the thyroid cartilage is attached to the hyoid bone by the thyrohyoid membrane. The thyroid cartilage is found between the levels of the C4 to C5 vertebrae. The oblique line is a line on the thyroid cartilage. It marks the upper lateral borders of the thyroid gland.
The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine.
Thyroglossal cysts are the most common cause of midline neck masses and are generally located caudal to (below) the hyoid bone. These neck masses can occur anywhere along the path of the thyroglossal duct, from the base of the tongue to the suprasternal notch. [2]
Of the fracture to her hyoid bone, he said: “It depends on the setting but in the setting of neck compression, it’s fractured in 25 per cent of cases, the most common type of cases is manual ...
Since the hyoid bone is the most important anatomic structure in the neck that limits the spread of infection, the spaces can be classified according to their relation to the hyoid bone: [5] Suprahyoid (above the hyoid) Infrahyoid (below the hyoid) Fascial spaces traversing the length of the neck
