Symphysis and parasymphysis - complex

These are complex fractures in the area between the canine teeth of the mandible.

Complex fractures include:

• Comminuted fractures
• Chronically infected simple fractures
• Defect fractures

This image shows an axial CT view of a comminuted symphyseal fracture.

This image shows a coronal CT view of the same case.

3-D reconstructions of comminuted fractures are also useful in understanding the fracture morphology.

This image shows another view of the 3-D reconstruction for the case above.

This is the clinical photograph of the same case.

This more severe type of mandibular symphyseal fracture results from heavy impact during a physical altercation or traffic accidents.
