hyoid bone fracture

27 Jan

rare, due to protected location of the larynx (mandible is superior and anterior and spine is posterior)

Hyoid bone fractures from blunt trauma other than strangulation = 0.002%
Respiratory distress can progress rapidly: hematoma formation and soft tissue swelling leads to airway compromise and hypoxia

–Laryngeal injuries occur more commonly in males (77% vs 33%)

–Women have slimmer longer necks so they are more prone to hyoid bone fractures
symptoms: horseness, neck pain, dyspnea, dysphonia, aphonia, dysphasia, odynophonia/phagia, stridor (inspiratory), hemoptysis, subcutaneous emphysema, hematoma, ecchymosis, crepitus, loss of landmarks
Associated injuries w/laryngeal fractures: intracranial injury (13%), open neck injury (9%), C-spine fx (8%), esophageal injury (3%)
hyoid bone fractures are rare
most are from strangulation, few from blunt trauma
respiratory compromise is the big issue (duh)
–associated with other head & neck badness
