This is a clinical study on 235 inpatients who sustained a total of 350 mandibular fractures and who were treated in our department during the period of Oug., 1989 through Dec., 1993.
@ES The results obtained are as follows :
@EN 1. The mumber of patients has not been increased year after year.
In respect of incidence, there were the highest frequency as 67 patients(28.5%) in 1991 and the least frequency as 16 patients(6.8%) in 1989 and the highest frequency as 28 patients (1.9%) in October and the least frequncy as 12 patients(5.2%) in
February.
2. The age frequency was highest in the second decade(30.6%).
The youngest patient was 8 months and the eldest patient was 80 years and mean age was 27.8 years. The ratio of men to Wemen was 4 : 1.
3. The most frequent cause was fall down as 86 patients(36.6%) and the next was fist blow as 75 patients(31.9%), traffic accident as 56 patients(23.9%) in order.
4. The most common location was symphysis as 141 numbers(40.3%) and the next was condyle as 96 numbers(27.4%), angle as 94 numbers(26.8%), body as 14 numbers(4.0%) in order. The sum of fracture sites were 350 and there were 1.49 fracture sites
per
one
patient and multiple fractures occured in 100 patients(40.5%) of the 235 patients. The ratio of Left to Right except for symphysis was 1.71 : 1
5. Among the 333 associated injuries, facial laceration was 136(57.9%) and tooth injury was 58(24.7%) and extremity was 31(13.2%).
6. Among the 350 mandibular fractures, complications after treatment occured in 51(14.6%) and infection as 20(5.7%) was the most frequent complication.
7. In respect of treatment of mandibular fracture, close reduction was 64 patients(27.2%) and open reduction was 164 patients(69.8%) and other were 7 patients(3.0%) of all and so open reduction was the most common in type of treatment.
