A clinico statistical study of 123 condylar fractures of the mandible

123 mandibular condylar fractures treated at our department from January 1986 to December 1991 were reviewed and analysed.Their characteristics were as follows:1. Condylar fractures occurred in 49. 6% of the mandibular fractures and the male: female ratio was 1.5 to 1. The largest age group of patients was from 15 to below 20 years (24. 4%).2. The most frequent cause of condylar fracture was traffic accidents (51.2%).3. Of 123 cases, 99 (80.5%) were unilateral, 24 (19.5%) were bilateral, and 61 (49.6%) were complicated by other mandibular fractures. The overwhelning majority of cases (95.0%) were indirect fractures.4. Fractures with displacement and/or dislocation occurred most frequently in the condylar superior neck region (22.0%).5. Of 147 condyles, closed reduction for mandibular condylar fracture was performed in 122 (83.0%) condyles and open reduction was perfomed in 25 condyles (17.0%).6. As for the clinical results in 106 cases, 91 (86.0%) were completely healed and 15 cases (14.0%) had disorder 1. Results in the patients treated were generally good.
