Twenty-six patients were treated within a week of injury, 22 cases within 2-weeks and 33 cases were treated afler more tham 3 weeks.3. Of the 100 cases, 70 were unilateral fractures and 30 were bilateral. The incidence of the concomitant fractures of the mandible were higher in bilateral than in unilateral condylar fractures.4. On fracture level and formn 130-site in 100 patients were divided according to the classification of Maclennan and Kubo. Dislocated and high condylar fractures were most frquently observed.5.
