ANATOMY

Detailed explanation-1: -Famously, the hyoid bone is the only bone in humans that does not articulate with any other bone, but only has muscular, ligamentous, and cartilaginous attachments. Given this peculiarity, it has been described as “free floating” [1].

Detailed explanation-2: -The most common symptom is point tenderness at the lateral aspect of the hyoid or superior cornu of the thyroid cartilage. Other typical symptoms may include neck and facial pain, throat pain, sensation of foreign body in throat, odynophagia, dysphonia, and obstructive sleep apnea.

Detailed explanation-3: -The hyoid bone moves during swallowing as a result of suprahyoid muscle contraction. Hyoid movement is required for adequate opening of the upper esophageal sphincter (UES) and is readily measured from a videofluoroscopic dynamic swallow study.

Detailed explanation-4: -Abstract. The hyoid bone is a small horseshoe-shaped bone located between the mandible and the shoulder girdle. It is classified as a sesamoid bone which means it is a freely floating bone. However, it is anything but freely floating.

Detailed explanation-5: -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.
