Abstract
The condylar fractures were accounted for 18-35.5% of mandibular fractures. They were attempted to classify with various methods in the previous clinical study. This study was based on the clinical charts and X-ray films, were pertained to the 163 patients who had the condylar fractures. And condylar fractures were classified with respect to 1) the level of the fracture 2) dislocation at the fracture level
3) position of the condylar head against the articular fossa. Then, the results were verified in regard to the ages, causes and other mandibular fractures to find the correlating factors.
The results were as follows
1. The most common trauma, associated with condylar fractures was fall injury and it is especially true in children.
While the head and neck fractures showed a tendency to associate with fall injury and to occur in children, the subcondylar fractures were associated with blow injury and occurred in adults.
The head and neck fractures exhibited a tendency that fractured head was dislocated and fracture edge was overrided at the medial side. In the subcondylar fractures many cases were preserved the normal condylar position and had a tendency to override laterally.
The displacement of condyle against the articular fossa was related to the state of override at the fracture level. The override at the fracture level was related to trauma and location of fracture.
Most of the concomitant fractures were occurred at the symphysis, occurred in adults and were related to the subcondylar fractures.
