Occurrence and characteristics of mandibular fractures in Nairobi, Kenya
1Oral Health Research Programme, Medical Research Centre, Nairobi, Kenya.
Abstract:
Analysis of 355 cases with fractures of the mandible indicated that 74.9% of the cases were due to interpersonal violence and 13.8% were caused by road traffic accidents. The men to women ratio was 8.4:1 and 75.5% of the fracture cases had single fractures while 24.5% had multiple fractures. In cases with a single fracture, the most commonly involved mandibular site was the body (42.2%). The angle of mandible was most frequently fractured (50.5%) in cases with multiple fractures.
Insights
Interpersonal violence is the leading cause of mandible fractures, significantly more common in men. Most fractures are single, often affecting the mandibular body, while multiple fractures frequently involve the angle.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
- Public Health
Background:
- Mandible fractures are common facial injuries.
- Understanding the etiology and patterns of these fractures is crucial for effective treatment and prevention strategies.
Purpose of the Study:
- To analyze the causes, demographic distribution, and fracture patterns of mandible fractures.
- To identify the most frequent sites of single and multiple mandibular fractures.
Main Methods:
- Retrospective analysis of 355 patient cases with mandible fractures.
- Data collection included fracture etiology, patient demographics (sex), and fracture characteristics (single vs. multiple, location).
Main Results:
- Interpersonal violence (74.9%) and road traffic accidents (13.8%) were the primary causes.
- A male predominance was observed (8.4:1 ratio).
- Single fractures (75.5%) most commonly involved the mandibular body (42.2%), whereas multiple fractures (24.5%) frequently occurred at the mandibular angle (50.5%).
Conclusions:
- Mandible fractures are predominantly caused by interpersonal violence and affect men more than women.
- Fracture patterns differ based on whether they are single or multiple, highlighting specific anatomical sites for concern.
