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.
分析了113例121处下颌角骨折患者依据坚固内固定原则进行治疗的数据，以确定哪些临床因素与不同并发症相关。发现某些临床特征与主要并发症相关。使用加压接骨板似乎存在一些弊端，会导致一些并发症。由于骨表面横截面相对较小以及角部区域特殊的解剖特征，通常无法进行良好调整的骨折块间加压。对于坚固性骨固定，中性重建接骨板被认为是最佳选择。如果骨折线上的磨牙必须拔除，应在骨折稳定后进行。在大多数情况下，无法避免采用口外入路，但与该入路相关的并发症很少见，且患者耐受性良好。
