The stucy based on a series of 112 patients who had treated for the fractures of mandibular condyle on Kyunghee Dental Hospital from January, 1989 to August 1997. We studied the age and sex distributions, causes of fractures, location of fractures and so on. The results as follow : 1.

The most common cause of condylar fractures was fall-down(47.7%), followed in incidence by direct-blow(27.9%) and traffic accidents(20.7%). 3. Subcondylar fracture had highest incidence(50%), and followed by condyle head(27.4%) and condylar neck(22.6%). 4. 9.7% of condylar fractures had occurred bilaterally and in cases of bilateral condylar fractures, condylar head fractures(58.33%) was hightest incidence. 5.
