Clinical features:

  • bruising and swelling
  • dental trauma
  • pain at the site of the fracture
  • sublingual haematoma (this is characteristic of mandibular fracture)
  • abnormal mobility of jaw
  • crepitus (do not test for this)

Immediate treatment:

  • make sure airway not obstructed
  • immobilise with bandaging to reduce pain during transport to hospital
  • Pethidine 50-100mg with Prochlorperazine 12.5mg i.m. if needed
  • avoid Morphine and Diamorphine in head injury cases as it obscures important signs such as pupil reactions
  • refer to A/E dept
