The hyoid bone is a U-shaped bone in the neck located above the thyroid cartilage (Adam’s apple). The hyoid bone is attached to important structures, but the bone itself is not held firmly in position. Because the hyoid bone has this ability to move around, the structures attached to it can contribute to obstructive sleep apnea.
The hyoid suspension procedure involves moving the hyoid bone forward and placing sutures to hold it in position, typically by securing it to the thyroid cartilage. Hyoid suspension is performed under general anesthesia.
