Craniomaxillofacial Trauma & Reconstruction

Summary
Trauma mechanisms significantly influence mandibular fracture locations. Understanding these patterns aids in diagnosing and planning surgeries for mandible fractures caused by aggression, falls, or accidents.
Area of Science:
- Maxillofacial Surgery
- Trauma Surgery
- Orthopedic Surgery
Background:
- The mandible is frequently affected by maxillofacial trauma due to its anatomical position and function.
- Fracture patterns are influenced by impact mechanisms and bone characteristics.
- Understanding the relationship between trauma and fracture location is crucial for effective treatment.
Purpose of the Study:
- To analyze the relationship between trauma mechanisms and affected anatomical subsites in isolated mandibular fractures.
- To provide insights for improved diagnostic assessment and surgical planning in maxillofacial trauma.
Main Methods:
- Retrospective cross-sectional observational study.
- Analysis of medical records, surgical reports, and diagnostic imaging (2011-2024).
- Classification of trauma mechanisms: interpersonal aggression, vehicular accidents, falls, sports, blunt objects.
Main Results:
- Interpersonal aggression was the most frequent trauma mechanism.
- The mandibular angle, parasymphysis, and condyle were most commonly fractured.
- Falls and vehicular accidents were associated with higher condylar fracture probability.
- Blunt object trauma correlated with mandibular body fractures.
Conclusions:
- Trauma mechanisms are key determinants of mandibular fracture location.
- Specific mechanisms correlate with distinct fracture patterns, aiding clinical decision-making.
- Findings support tailored diagnostic and surgical approaches for mandibular fractures.
