The hyoid is situated at the front, or anterior, part of the neck between the jaw bone and the thyroid cartilage, and is firmly secured to the thyroid cartilage by ligaments. supports the tongue, providing attachment sites for muscles of the tongue, neck, and pharynx. Hyoid Bone Location. [10] It is necessary to take into consideration the skull base, the mandible and the cervical vertebrae and a cranial reference plane. It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves. [11][12], A large number of muscles attach to the hyoid:[13]. The hyoid bone refers to a bone located in the front middle section of the neck, between the thyroid cartilage and the chin. The hyoid bone (“U-shaped” bone) lies just inferior to the mandible (between the mandible and the thyroid cartilage) in the anterior portion of the neck at the level of the C3 vertebra. The hyoid bone is a ‘U’ shaped structure located in the anterior neck.

The suprahyoid branch of the lingual artery runs along the upper border of the hyoid bone and supplies blood to the attached muscles. Ossification commences in the greater cornua toward the end of fetal development, in the hyoid body shortly afterward, and in the lesser cornua during the first or second year after birth. The hyoid bone is frequently fractured as a result of strangulation. Chris Vincent, MD, is a licensed physician, surgeon, and board-certified doctor of family medicine.

[16][17] Movement of the hyoid bone is also thought to be important in modifying upper airway properties, which was recently demonstrated in computer model simulations. It allows a wider range of tongue, pharyngeal and laryngeal movements by bracing these structures alongside each other in order to produce variation. However, this is not necessarily the case in children and adolescents, where the hyoid bone is still flexible as ossification is yet to be completed. The position of the hyoid bone is influenced by the position of the tongue, thus affecting the pharyngeal airway space. The hyoid provides an attachment site for muscles that control movements of the larynx.. One of the easiest diagnostic criteria for sleep apnoea is cephalometric diagnosis of the hyoid bone. 7 Thurow proposed that the anteroposterior position of the hyoid is maintained by the geniohyoid muscle due to which airway patency was maintained throughout the various movements of the craniofacial complex.

[21] In humans, the single hyoid bone is an equivalent of the hyoid apparatus. The largest of muscles that attach to the upper surface of the greater horns are the hyoglossus and the middle pharyngeal constrictor, which extend along the whole length of the horns; the digastric muscle and stylohyoid muscle have small insertions in front of these near the junction of the body with the horns. The hyoid bone is located in the neck and can be palpated immediately above the thyroid cartilage (the protuberance on the anterior surface of the neck). Irregular bones are those which have unique shapes. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. The hyoid bone is important to a number of physiological functions, including breathing, swallowing and speech. Malignant tumors of the hyoid bone are rare and include sarcomas, plasmacytomas, and distant metastases.
