Abstract: Objective To explore the clinical application and effect?of the small titanium plate with intermaxillary traction titanium nail in the fixation of Mandibular fracture. Methods Retrospective analysis was achieved from the clinical data of 186 cases of Mandibular fracture treated by the small titanium plate with intermaxillary traction titanium nail. In all cases, titanium nails were used for intermaxillary traction to restore the occlusal relationship. Small titanium plates were used for the internal fixation of the mandibular fracture through the hidden minimally invasive incision or the original open wound. Results All the wounds were healed by first intension. All patients regained normal mouth opening, good facial appearance, mastication function and occlusion recovery. The clinical cure rate was 100%. X-ray showed good fracture healing, no loose, shift, fracture of titanium plate or nail was observed, and no osteoporosis and bone resorption was observed. Conclusion Using the small titanium plate with intermaxillary traction titanium nail for the treatment of Mandibular fracture is proved to be convenient and effective with minimally invasive incision and accurately reduction, and is worthy of wide application.
