Inclusion criteria

Inclusion criteria: Patients with a history of displaced fractures of the mandibular body, angle, or ramus Displacement of fracture segments in panoramic radiograph should delineate complete nerve severance (Sunderland 5) Patients who have received ideal treatment of open reduction and internal fixation At least six months have elapsed since open reduction and internal fixation treatment, and the neurosensory disorder persists. All patients should be systemically healthy.
