AOCMF Classification System

After about 10 years of development, AOCMF presents the first AO classification system for fractures of the craniomaxillofacial skeleton together with the AOCOIAC (AO Comprehensive Injury Automatic Classifier) software solution.

This new comprehensive AOCMF classification system for fractures in the adult craniomaxillofacial skeleton is organized in anatomic modules in a three precision-level hierarchy with a brief account for increasing complexity and other details:

  • Level-1: Most elementary. It identifies no more than the presence of fractures in 4 separate anatomical units: the mandible (code 91), midface (92), skull base (93) and cranial vault (94)
  • Level-2: This relates the detailed topographic location of the fractures within defined regions of the mandible, central and lateral midface, internal orbit, endo- and exocranial skull base, and the cranial vault
  • Level-3: Based on a more refined topographic assessment. It focuses on the morphology—fragmentation, displacement, and bone defects—within specified sub regions.

For use of the AOCOIAC software, its manuals and all case examples, the AO Foundation terms, conditions, and disclaimers apply.
