results
were as follows:
1. Of the 904 patients with facial bone fractures, 75 patients were under 15 years of age(8%) with male to female ratio 1.3:1.
2. The incidence of facial bone fractures in the group of 6 to 10 years of age was highest of all(37.3%), but there were no statistically significant difference among the 3 groups.(P>0.05).
3. Falls were ranked as the predominent cause(52%), followed by traffic accident(41%), play ground(4%). These was no correlation statistically between Increased number of patient and annual growth rate.(P>0.05).
4. The monthly incidence of pediatric fracture was highest in the April and September(12.0%).
5. The incidence of mandibular fracutres(80%0 was the highest of all pediatric fractures, and, of mandibular fractures, the condylar fractures occurred most frequently(73%).
6. Of associated injuries, abrasion and contusion of soft tissue occurred most frequently(43%), followed by laceration(39%).
7. Of the managements of facial bone fractures, closed reduction was 71%(49cases), and open reduction 29%(20cases).
8. Intermaxillary fixation was done in 42(70%) of 60 patients withjaw fractures and its period was less than 3 weeks in most cases(83%). The monomaxillary fixation was done, for the most part, in the mandibular fractures and its period was also
less
than 3 weeks in most cases (62%).
9. The mean hospitalized period was 13.4 days, and 68 of 75 patients were treated within 1 weeks(91%).
10. The complications such as deviation of chin(4 cases), abnormal sensation(3 cases), infection (3 cases), mulocclusion(1 case) and TMJ ankylosis(1 case) occurred in the pediatric fracture patients.
