Physical examination revealed tenderness over right chin and malar region, entire right side of maxilla was mobile with a midline split of maxilla, avulsion of mandibular incisors, tenderness on palpation of left side of hyoid bone with no external wounds noticed on neck except for some blunt traumatic injuries. The patient had no dyspnoea or signs of airway compromise. His symptoms on presentation were a constant and severe neck pain, localized on the left side, with marked odynophagia when opening his mouth, swallowing or speaking. The following paper presents a thorough review of case of hyoid bone fracture associated with panfacial trauma in a 24 year old male.Ī 24 year old man presented to the casualty and emergency care with a complaint of pain over the face and neck region following a road traffic accident. Because of its morphology and its position amongst the other anatomical structures of the neck, it is associated not only with the sound production and the fully articulate human speech, but also with the smooth function of the airway and possibly with the normal swallowing. The primary function of hyoid bone is to provide attachment to the tongue, the larynx and the pharynx. The greater and lesser cornua fuse to body of hyoid bone between 40 and 60 years of age although non-fusion has been found even after the age of 60 years. It is composed of a body, two greater and two lesser horns and is a unique bone which is articulated to other bones by muscles or ligaments. It’s name originated from the Greek word hyoeides, which means “shaped like the letter upsilon” which represents the 20th letter in the Greek alphabets. The hyoid bone is a U-shaped mobile bone situated in the anterior portion of the neck at the level of the C3 vertebra, in the angle between the mandible and the thyroid cartilage. The fracture of this bone is very rare accounting for only 0.002 % of all fractures. In survivors it is more often associated with a trauma other than manual strangulation. ![]() The most commonly reported injury is fracture, yet this is often a post-mortem finding, with an incidence of between 17–76 %, in victims of strangulation and hanging.
