Abstract :We have analysed 93 patients with mandibular angle fractures during the past 6 years (1985-1990)at the Department of Oral Surgery, University of the Ryukyus Hospital. The results were as follows: 1) In age distribution.the twenties and the thirties were the most numerous (81.7%)and the male/female ratio was 5.2:1.2) The major cause of fractures were blows(55.9%). 3)As to the treatment of the 93 cases, 58 cases were treated by closed reduction and 35 cases were treated by open reduction. Recently, the cases of open reduction using a miniplate have been on the increase. 4) Regarding treatment based on the degree of displacement of the bone fragment,55 cases (59.1%) of grades I and II were treated by intermaxillary fixation. The majority of grades II and III were treated by open reduction. 5) In 35 open reduction cases,the intraoral approach was used in 21 cases and the extraoral approach was used in 14 cases. Recently, the intraoral approach using a miniplate was mainly used for open reduction. 6)In the latter 3 years, the period of intermaxillary fixation after open reduction was shortened to 7 days. The clinical results were most satisfactory except in only two cases. Malocclusion was observed in two cases treated with an A-O plate in the latter 3 years, but these were treated again with a miniplate and the prognosis was good.
