A clinical study of 65 patients with maxillofacial fractures who visited our hospital from April 2008 to March 2013 was conducted.
The patients consisted of 53 males and 12 females, a male-to-female ratio of 4.4：1. The patients ranged in age from 2 to 90 years old. The most common age range was 20-30 years old with 18 cases （27％）, with around 10 cases （15％） in each of the 10-20, 30-40, and 40-50 ranges.
The causes of injury included 19 cases of falls （29.2％）, 18 cases of horse-related accidents （28％）, 12 cases of sports accidents （18.5％）, 6 cases of traffic accidents （9％）, 5 cases of a blow （8％）, and 3 cases of work accidents （5％）. The main fracture site was the mandible （43 cases, 66.2％）, the mid face （22 cases, 33.8％）, and multiple facial bone fracture （5 cases, 7.7％）. Fracture sites of the mandible were 20 incisor region, 11 molar region, 14 mandibular angle, and 26 condylar process. Twenty-nine patients were treated by open reduction, 23 were treated conservatively, 13 were moved to other hospitals.
The results showed that the ratio of fractures caused by horses was remarkably high compared to other regions.
