| Popis: | Clinical statistics were conducted on 511 hospitalized cases of jaw fractures at the Department of Oral Surgery, Mie University Hospital during the 24-year period from 1960 to 1983.Inpatients in this period totaled 2, 290 cases.The incidence of fractures was 24.1% of all inpatients.1) The number of patients with jaw fractures each year tended to increase from 1960 to 1970, but there was almost no change from around 1971 to 1983.2) The male/female ratio was 4.5: 1, but the ratio in the past eight years narrowed the gap to 3.5: 1.3) The seasonal variation in the incidence of fractures was not significant.4) The most common causes of injury were traffic accidents in both males and females, especially female fractures were more by traffic accident than from any other cause.5) Fracture of the incisive region was the most common.6) The average fixation time for old fractures was slightly longer than that of fresh fractures but in the past eight years there was no difference between them, and it tended to be shorter. |
