ABSTRACT:-
BACKGROUND Hyoid bone is also been called the skeleton of the tongue. Its origin lies within the second and third pharyngeal arch cartilages. Hyoid bone is unusual in that it relates with no other bone, it is suspended by means of muscular, ligamentous and fascial attachments of the mandible, pharynx, and craniospinal complex. By virtue of all these attachments hyoid bone is important in many aspects, such as balancing head on the spinal cord , prevention of regurgitation of bolus, opening of the oral cavity, maintenance of stability and patency of the pharyngeal airway. Hyoid bone position can be studied with the help of lateral cephalogram. Bibby has introduced “HYOID TRIANGLE” to determine the anteroposterior position of hyoid bone with reference to third cervical vertebra and mandible. The relationship between the hyoid bone and mandible is maintained from the age of three years. Thus the anteroposterior position of hyoid bone is used to asses normal physiologic position and functions of the surrounding anatomy in this area, which is important in orthodontic and surgical relapse.
