Maxillofacial fractures related to work accidents.

Work-related maxillofacial fractures were studied retrospectively over a six-year period. There were 98 cases accounting for 4.5% of all facial bone fractures treated in our hospital between 1981 and 1986. Of the patients, 89.8% were male. The mean age of the injured was 36.4 years. The incidence of work-related maxillofacial fractures was 0.37 per 1000 workers. Most of the injuries (66%) occurred in factories and construction work. Such work was associated with an to 15 times higher risk of maxillofacial fracture than service and office work. Of the fractures, 20.4% were sustained on the way to or coming from work. At the place of work, the commonest causes of injury were blows from objects or falls from a height (70%). On the way to or coming from work, the aetiological factor was most often a traffic accident. Assault and battery had caused facial bone fractures in 11.2% of cases. Fifty-five patients with midface and 45 patients with mandibular fractures were found, of these, 8 patients had bimaxillary fractures. In 6 cases, only dentoalveolar fractures were found. Of the patients, 55.1% were treated operatively. Sixty-six patients were hospitalized, the mean length of hospital stay being 3.2 days (range 1-12 days).
