Clinicostatistical observations were performed on 172 cases of oral and maxillofacial injuries in children under 16 years of age at the Second Department of Oral and Maxillofacial Surgery, faculty of dentistry Osaka University during the 5 years from 1986 to 1990. The following conclusions were drawn. 1. The number of children with injuries each year was almost no change from 1986 to 1990. 2. The incidence of traumas in children was 27% of all patients with injuries. Of 172 cases of children with injuries, 35 (20%) suffered jaw body fractures, 25 (15%) had alveolar bone fractures, 70 (41%) suffered teeth injuries and 42 (24%) had soft tissue injuries. 3. The frequency of traumas was higher in May than in the other months and lower in February. There were higher on Friday and/or Sunday than in the other days and lower on Tuesday. 4. The ratio of male to female was 1.7: 1. 5. By age distribution, under 4 and/or 13-16 age group showed a high incidence. 6. The common causes of oral and maxillofacial injuries were falls (51%), traffic accidents (26%) and sports (7%). 7. The ratio of mandibular fracture to midface fracture was 6.6: 1. The common sites of mandibular fractures were condyle (41.5%), symphysis (24.5%) and angle (15.1%). The most common site of alveolar bone fractures was the symphysis in the upper jaw and that of the teeth injuries was the anterior teeth in the upper jaw. 8. Open reduction for jaw body fractures was performed on 13 cases (36%). The bone fixation was performed using interosseous wiring and/or mini plate. The most common treatment for the alveolar bone fracture was teeth fixation (54.2%) and that for the teeth injuries was also teeth fixation (50%).
