Hospitalized cases of maxillofacial fractures during 12 years (1976-1987) at our Department are investigated in this paper. These cases were classified into two period groups: one was the former group (1976-Aug. 1981) and the other was the latter (Sept. 1981-1987). comprising 145 cases and 150 cases, respectively. The former group was already published and the latter was clinico-statistically compared with regard to social environment.
Furthermore, these total cases were discussed as a whole.
1) Male to female ratio was 5: 1 in all, but female ratio showed an increasing tendency only in the latter group.
2) Patients in their teens and twenties formed 50.5 percent of all cases and increased in the latter group.
3) The most frequent cause was traffic accident and work accident markedly decreased in the latter group.
4) Mandibular fractures accounted for 73.6 percent of total cases. Their most frequent site was the region of incisal teeth (25.4%), followed by condylar process (11.3%), mandibular angle (11.2%), and so on.
5) Patients introduced by general practitioners markedly increased in the latter group.
6) The ratio of surgery to non-surgically conservative treatment was 3: 2.
7) Duration of hospitalization and intermaxillary with ligation became shortened in the latter group.
8) Discomfortable symptoms were not left after treatments and most patients were satisfied with the clinical results, except only several cases.
