Methods of stabilisation
- Osteosynthesis
- Antral support
- External pin fixation
- Internal pin fixation
Osteosythesis
- Miniplate fixation at F-Z suture
- Microplate fixation at Infra-Orbital rim
- Miniplate fixation at zygomatic buttress
- Microplate fixation at zygomatic arch
- Transosseous wires less rigid and less stable
Antral Support
- Rarely used
- Gross comminution of zygoma and antral walls
- Antral pack of gauze soaked in Whiteheads Varnish
- Antral balloon
- If comminuted orbital floor ? Risk of displacement of bony fragment and trauma to optic nerve
External Pin Fixation
- Frontal-Zygomatic sutures
- Pin placed in body of zygoma
- Pin placed in supra-orbital ridge
- Pins connected rigidly by vertical rod and universal joints
'
Internal Pin Fixation
- Transnasal K wire—opposite unfractured zygoma used as stable base to rigidly hold fractured zygoma via transversely placed K wire
- Removal at 3—6 weeks
