Abstract

As modern society becomes very complex, there has been steady increase in violence, and automobile and industrial accidents. This has resulted in the increased incidence of facial injuries including mandible fracture. We have analyzed 135 such cases from May, 1972 through May, 1984 at the Department of Plastic and Reconstructive Surgery, Han-yang University Hospital. The result we found includes: 1. Ratio of incidence between male and female was 4 to l. 2. Highest incidence was in the 21 to 30 years age group. 3, Most common cause was the automobile accident (53.3%). 4. Regional frequencies of mandibular fracture were; symphysis (41.9%) angle (21. 5%) condyle (18. 8%) body (13. 3%) ramus (1. 7%) coronoid process (l. 7%) alveolus (l. 1%) 5. Most common associated injury was other facial bone fracture (23.2%). 6.Most common complication was postoperative wound infection (3%). 7. There were more simple fractures (67.4%) than multiple fractures (32.6%), which are on the increase.
