We studied maxillofacial fractures treated by departments of oral and maxillofacial surgery in Tokyo. A retrospective review of records and radiographs for patients admitted during the 5-year period from 2000 to 2004 was conducted at five departments in Tokyo. Date, age, gender, cause of injury, fracture site, concomitant injury, domestic violence against women, and treatment were reviewed. 674 patients with maxillofacial fractures were admitted. Male-to-female ratio was 3.6:1. The most frequent age group was 21-25 years. Fractures of the mandible were most frequent (87%), followed by the maxilla (14%) and the zygomatic bone (12%). Thirty-one percent of fractures were due to traffic accidents, 29% to accidental falls, 23% to violence and 14% to sports. The incidence of maxillofacial fractures caused by traffic accidents was lower, and that caused by falls and violence were higher than in other countries. Seventeen percent of the maxillofacial fracture patients had concomitant injuries. The incidence of domestic violence-related maxillofacial fracture was 1.6% of all cases. These cases were mainly caused by a husband (55%) or a sexual partner (36%). Most patients (67%) were treated by open reduction surgery. However, condylar fracture alone was usually treated by closed reduction surgery.
