Abstract
Objective

This study aimed to evaluate and compare the demographic characteristics of mandibular condylar fractures between children and adolescents.

Methods

The sample was composed of all children (less than 12 years) and adolescents (between 13 and 18 years old) who presented with mandibular condylar fractures within a 5-year period (January 2011 to April 2016). The age, gender, time of injury, mechanism of trauma, location and pattern of fracture, associated injuries and treatment methods were recorded and analysed. Data analysis included chi-square test and Fisher exact test. Differences at p less than 0.05 were considered significant.

Results

A total of 111 children and 39 adolescent patients with condylar fractures were registered and compared. More children than adolescents were involved in falls from a height (p=0.007), but nearly no relationship was observed between the trauma aetiology and type of condylar fracture in the two patient groups. Condylar head fractures occurred most frequently in the children and adolescents, especially in the children (p<0.05). Condylar neck fractures were more frequently observed in the adolescent patients (p<0.001) than in the children. Green-stick fractures occurred only in the child patients (p=0.005). The patients who fractured other sites of the mandible tended to show a decreased frequency of dislocation (condylar head was out of the glenoid fossa) (p=0.024). Symphysis/para-symphysis fractures were highly common in the children who sustained unilateral condylar fractures (p<0.05). The patients with bilateral condylar fractures were more frequently associated with other mandibular fractures (children, p=0.001; adolescents, p=0.011), especially the fracture of the mandibular body or symphysis. The children who sustained extracapsular fractures were more prone to fractures of other mandibular sites (p=0.009), especially fracture of the symphysis/para-symphysis (p=0.014). Intracapsular fractures in children were treated non-surgically more frequently than surgically (p<0.001). The extracapsular fractures (mild and serious fractures) in children were also treated non-surgically more frequently (p<0.05).

Conclusions

The trauma mechanisms, incidence, pattern and treatment of condylar fractures in children substantially differ from those in adolescents. This study was conducted to enable the understanding of the differences in condylar fractures between children and adolescents. Accordingly, preventive measures and treatment plans in children or adolescents should be applied differently.
