International classifications of diseases(ICD-9)

• 802.20 - closed fracture of mandible, unspecified site

• 802.25 - closed fracture of mandible, angle of jaw

Objectives:

• The purpose was to analyze mandibular angle fractures (MAFs), looking at

epidemiological trends and mechanisms of injury, and to determine if a

statistically significant relationship existed between certain treatment

modalities and patient outcomes

Results

• Common concomitant fracture - Contralateral Parasymphysis.

• A statistically significant relationship was noted between methods of fixation and healing, as

well as overall patient comfort, with the Reconstruction plate being associated with the

Champy technique highest rates of bony union and patient Comfort

• No statistically significant correlation was found between methods of fixation and rates of

infection.

• There was no statistically significant link between extraction versus retention of healthy teeth

in the line of fracture or use of IMF with patient comfort, post-operative infection, or fracture

healing.

critical appraisal of conclusion

• Despite the fact that the Champy technique and reconstruction plates were associated with

better post-operative outcomes such as patient comfort and fracture healing, these should

not be used interchangeably, operator experience is important and clinical IMF and

extraction versus retention of teeth in the line of fracture did not influence any of the

outcomes.

Champy’s ideal line of osteosynthesis

For angle fractures the ideal line of osteosynthesis is located along the external oblique ridge (A). If it is not possible to plate this area, a miniplate located along the lateral surface of the mandible can also be used (B).
