Rigid Internal Fixation of Fractures in the Angular Region of the Mandible: an Analysis of Factors Contributing to Different Complications

Data relating to 113 patients with 121 mandibular angle fractures treated according to the principles of rigid internal fixation were analyzed to determine which clinical factors are associated with different complications. Certain clinical characteristics were found to be associated with major complications. The use of compression plates seemed to entail disadvantages resulting in some complications. Because of the relatively small cross section of bone surface and particular anatomic features of the angular region, well-adjusted interfragmentary compression is often not possible. A neutral reconstruction plate is considered optimal for rigid osteosynthesis. If a molar tooth in the fracture line has to be extracted, this should be done after fracture stabilization. In most cases, an extraoral approach could not be avoided, but complications associated with this approach were infrequent and well tolerated by patients.
