Eligibility
Inclusion criteria
Inclusion criteria: 1.Comminuted fractures. Severe open or infected fractures of the mandible caused by traffic accidents or other reasons; patients with mandibular fractures who also have concomitant craniocerebral injury, pneumothorax, or abdominal organ injury that make specialized treatment impossible; or patients whose specialized condition is acceptable but cannot undergo immediate open reduction and internal fixation of the mandible due to reasons such as severe hypertension, acute cerebral infarction, or unstable control of hyperthyroidism; 2.Related diseases such as osteomyelitis. Patients requiring temporary intraoperative fixation during mandibular reconstruction and repair surgery; or patients with severe infection leading to pathological fractures, such as those with destruction of the mandible accompanied by severe infection caused by mandible osteomyelitis, medication-induced osteonecrosis, or radiation-induced osteonecrosis and other inflammatory diseases, who are not suitable for immediate partial mandibulectomy with simultaneous bone grafting or prosthetic repair for mandibular reconstruction, or who require temporary fixation with a reconstruction plate; 3.Mandibular defects caused by tumors or other reasons. Patients requiring temporary intraoperative fixation during mandibular reconstruction and repair surgery due to tumors or other causes; or patients requiring segmental mandibulectomy who are unable to undergo autologous bone grafts such as fibula or iliac bone transplantation, or alternative prosthetic repair at this stage, or patients with existing implants experiencing infection or other issues; 4.Patients who are fully informed of the content, benefits, and possible risks of this research project, and agree to participate in this study; 5.Patients who can communicate and interact normally, and are able to cooperate actively.
Exclusion criteria
Exclusion criteria: 1.Patients who meet the conditions for surgical open reduction and rigid internal fixation treatment; 2.Patients whose mandibular defect range involves both ascending rami, making it impossible to fix with a unilateral external fixation device; 3.Patients with epilepsy or mental disorders who are unable to cooperate with postoperative management; 4.Patients who are unwilling to bear the potential risks of this project, and thus cannot meet the follow-up requirements; 5.Patients without complete and authentic clinical data.
