A comparative evaluation of different treatment modalities for parasymphysis fractures: a pilot study.

Maxime Champy advised the use of two miniplates for parasymphysis fractures because of the high torsional forces in the anterior region of the mandible. According to him there is no need for intraoperative or postoperative intermaxillary fixation, but most surgeons use arch bars for intraoperative or postoperative intermaxillary fixation. This study evaluated the role of the lower arch bar as a tension band eliminating the need for an upper miniplate (tension band plate) in cases of parasymphysis fractures. 3 groups underwent treatment. In the first group, two titanium miniplates were placed across the fracture site along with Erich's arch bar for 6 weeks. In the second group, two titanium miniplates were used for osteosynthesis without Erich's arch bar. In the third group, one titanium miniplate was placed along with Erich's arch bar for 6 weeks. The results of third group were statistically non-significant compared with those of the first and second groups.
