Murr has provided an excellent discussion of the fundamental concepts of treating fractures of the angle of the mandible as well as discussing arguments in favor of and against several commonly used techniques. His comments are well-founded.
The decision algorithm used in the treatment of craniofacial fractures is quite complex. The first consideration is whether any treatment is required. If so, one must decide whether the reduction should be performed in an open or closed approach. A decision on what type of repair to undertake must be made, considering external vs internal fixation and fracture immobilization vs rigid fixation. If rigid fixation is chosen, one must choose between lag screws and compression and noncompression plating.
