Guidelines Summary

The AO craniomaxillofacial (CMF) classification identifies 3 levels of mandible fractures/dislocations [40] :

  • Level 1 dentifies the presence of fractures in 4 areas: mandible, midface, skull base, and cranial vault.
  • Level 2 describes the location of the fractures within those defined areas. 
  • Level 3 describes fracture morphology, such as fragmentation, displacement, and dislocation.
