Face - Tripod fracture - OM view
- A 'tripod' fracture has 4 visible components - not always all visible
- 1 - Orbital floor fracture
- 2 - Fracture of the lateral wall of the maxillary antrum
- 3 - Zygomatic arch fracture
- 4 - Widening of the zygomatico-frontal suture
- Increased density of the maxillary antrum is due to it filling with blood
Face - Tripod fracture - OM30 view
- The fractures are again shown on the Occipito-Mental 30 view
- The zygomatico-frontal suture (asterisk) appears relatively normal on this image and looks similar to the contralateral side
- A slightly wide zygomatico-frontal suture should not be taken as significant unless accompanied by other evidence of injury on the same side
