Retrospective analysis of 1502 patients with facial fractures.

A total of 1502 patients with facial fractures treated between 1981 and 1996 were retrospectively analysed. The male: female ratio was 2.8:1 and the largest subgroup of patients was between 10 and 29 years of age. The most common cause of injury was traffic accidents (52%) involving motorcycles, bicycles or automobiles. Other common causes included, in descending order, falls (16.6%), assaults (15.5%) and sports (9.7%). Isolated mandibular fractures were most common (56.9%), followed by isolated midface fractures (25.9%). The percentage of fractures involving both the midface and mandible was 6.7, and that of isolated alveolar fractures was 10.5.
