Abstract
A statistical study of 1415 cases with facial bone fractures examined at Showa University Hospital from 1994 to 2003 is presented. Data concerning sex, age, situation of the first examination, etiology, diagnosis and treatments were evaluated. The total number of cases investigated in this presentation is one of the largest in the literature. The number of patients increased during period examined. In addition the overall ratio of cases with facial bone fractures in all patients who consulted plastic and reconstructive physicians grew as well. Our results show that patients with facial bone fractures tended to be male (71.3%) between the ages of 10 to 39 years (68.7%) and were involved in assaults (24.4%) . 1522 regions of fractures were revealed in 1415 patients. The most common region of facial bone fracture was the nasal bone (56.5%) followed by the zygomatic bone (21.7%), mandible (13.1%), orbit (5.5%) and maxilla (3.2%) . Multiple fractures were recognized in 6.6% of all cases. In the mandible, the most frequent site of fracture was the condyle (48.2%) and the most common combination of fracture site was the unilateral condyle and the symphysis region (26.9%) . 56.3% of the patients were treated operatively at 8.0 days after injury on average. Only 0.7% of cases required additional surgery because of an unfavorable result in primary treatment.
