Abstract

The AOCMF Classification Group developed a hierarchical three-level craniomaxillofacial (CMF) fracture classification system. The fundamental level 1 distinguishes four major anatomical units including the mandible (code 91), midface (code 92), skull base (code 93) and cranial vault (code 94); level 2 relates to the location of the fractures within defined topographical regions within each units; level 3 relates to fracture morphology in these regions regarding fragmentation, displacement, and bone defects, as well as the involvement of specific anatomical structures. The resulting CMF classification system has been implemented into AO comprehensive injury automatic classifier (AOCOIAC) software allowing for fracture classification as well as clinical documentation of individual cases including a selected sample of diagnostic images. This tutorial highlights the main features of the software. In addition, a series of illustrative case examples is made available electronically for viewing and editing.

Keywords: classification system; coding; craniomaxillofacial fractures; electronic documentation system.

Classification by fracture drawing or mouse click. (A) A fractured region (level 2) is set in blue. (B) At the level 3 classification, lack of fragmentation, minor fragmentation (or simply "fragmentation" in the cranium) and major fragmentation (in the mandible) are show in yellow, (C) orange, and (D) red, respectively. (D) Partial edentulism and mild mandibular atrophy is illustrated.
