Up to now, most clinical and statistical analyses of Maxillofacial fractures have been done on the population as a whole. No detailed information on maxillofacial fractures specifically of high school students could be found despite the fact of high frequency of occurrence among this group. We conducted an investigation into the cases of maxillofacial fractures of high school students treated at the oral surgery department clinic of the Ryukyu University Hospital during the five year period from January, 1980 to December, 1984. We noted that 44 cases or 15. 4% of all patients with maxillofacial fracture were high school students. Males were found to be more prone to maxillofacial fracture than females (4.2: 1). First year students proved to be more prone to such fractures than second and third year students. Of the total cases, 19 (43%) were in-patients and 25 (57%) were out-patients. The causes of fractures were mostly traffic accidents (63%) especially two-wheeled vehicle accidents (50%), followed by fist blows and sports accidents (14%, respectively). Of all fractures, 29 cases (65%) were found in the mandible, 8 (18%) in the maxilla (including the middle third facial region), and 7 (17%) in the mandible and maxilla. In the mandible, the most frequent fractures were found in the region of the molar and angle, and the second most frequent were in the incisal area. Among the 44 cases, a total of 140 complications were observed; among those complications, 33 were found in the oral mucosa, 24 in the teeth, 27 in the facial skin. Twenty-one cases experienced unconsciousness and there were 6 cases with fractures other than facial. Only 4 cases (10%) were referred to us from private dental clinics. Thirty-two cases (73%) were referred from public and private hospitals, and the remaining cases from various other sources.
