Summary
Revision surgery after mandibular fractures often indicates severe complications. This study found osteomyelitis and pseudarthrosis were primary reasons for refixation, with risk factors like immune suppression and substance abuse playing a role. Treatment quality also impacts outcomes.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
- Orthognathic Surgery
Background:
- Revision surgery after mandibular fractures signifies significant postoperative complications.
- Characterizing patients requiring revision surgery is crucial for understanding and mitigating complications.
Purpose of the Study:
- To characterize patients needing revision surgery for mandibular fractures.
- To describe management strategies for postoperative complications.
- To evaluate treatment quality as a risk factor for complications.
Main Methods:
- Retrospective, descriptive observational study of patients undergoing refixation after open reduction and internal fixation (ORIF) of mandibular fractures.
- Patient and therapy data collected; postoperative complications assessed.
- Fixation quality evaluated by six specialists; interobserver agreement analyzed using Fleiss' kappa.
Main Results:
- 17 patients (average age 43.3 years) required revision surgery.
- Osteomyelitis (52.9%) and pseudarthrosis (41.2%) were main indications for refixation.
- Risk factors included immune suppression, local infection, and substance abuse; however, 4 of 6 patients without these predictors had treatment not adhering to AO principles. Interrater reliability was 0.239.
Conclusions:
- Patients with risk factors require vigilant perioperative monitoring and tailored treatment after ORIF of mandibular fractures.
- Deviations from treatment guidelines may independently predict failure, even in patients without identified risk factors.
- Re-evaluation of current treatment guidelines is needed to incorporate strategies for patients with specific risk factors.
