AOCMF classification system
New comprehensive AOCMF classification system for fractures in the adult craniomaxillofacial skeleton
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 of increasing complexity and other details:
Most elementary. It identifies no more than the presence of fractures in four separate anatomical units: the mandible (code 91), midface (92), skull base (93) and cranial vault (94).
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.
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.
