Abstract

Although there have been many clinical studies about the facial trauma in the recent as well as in the past, severity and frequency of facial trauma are reported multifarious. It seemed to be because of variety of social, cultural, and environmental factors, and the view point of investigators. In this study, we investigated about the patients visiting emergency room during recent 5 years(1999-2003), and compared with retrospective study during former 5 years(1992-1996) in Dept. OMS Pusan Univ-Hospital. We are assessed the cause, type, demographic ect. And analyzed alterations of facial bone fractures during past 2 periods. the results were as follows. The total number of patients was increased slightly. 429 patients treated for maxillofacial fractures between January 1992 and December 1996 and 466 patients treated between January 1992 and December 1996. The male-to-female ratio reduced in the second period by a factor of 0.7. Patients in the age groups of 10-19 years and 20-29 years increased by a factor of 4.2 and 7.9 in the second period. Assaults and falls in the second period decreased by a factor of 15.4 and 7.9. But, traffic accidents and slip downs in the second period increased by a factor of 6 and 6.6. The mandibular fractures(70.6%) showed the highest incidence, followed by zygomatic bone and arch fractures(7.5%), maxillary bone fractures(4.0%), and nasal bone fractures(4.0%). In the second period, the mid-face fracture was increased slightly. So, the mandibular fractures(69.0%) followed by maxillary bone fractures(12.9%), zygomatic bone and arch fractures(8.0%), nasal bone fractures(7.0%). Ramus fractures and body fractures of mandible was increased slightly in the second period.
