Retrospective Study Of Maxillofacial Injuries

Oral and maxillofacial region is exposed to the surface of human body, therefore it's very susceptible to trauma. Although maxillofacial injuries is not so severe and direct in threatening the life as vital organ injuries such as brain trauma, its damage to the mastication function and facial appearance along with concomitant psychological disturbances is much more serious. So epidemiological research is crucial to the treatment and prevention of facial trauma. However, researches in such field are scare, especially data of recent years.The present study utilized a standardized cases recording system to overview and analyze all cases of facial trauma in the past 3 years, in attempt to come up with new and comprehensive epidemiological characteristics of facial trauma. In this way we drew some conclusions of guidance in preventing and treating facial trauma. At the same time, we tested the efficacy of the case recording system.Retrospective Study of Maxillofacial InjuriesTo investigate epidemiological features of maxillofacial injuries and provide epidemiological information, 548 maxillofacial injuries from July 2003 to June 2006 were analyzed, including the age, gender, time distribution of injury, cause of injury, type of fracture and nerve injury, and associated systemic injuries.The majority of maxillofacial injuries were found in males, and the most prevalent age ranged from 21 to 40 years. The incidence of maxillofacial injuries was highest in July, and lowest in February .The leading cause of facial trauma was traffic accidents. Mandible fracture outranked maxillary and zygomatic arch fracture. Multiple fractures had higher prevelance than single fracture. The average number of fractures for each patient was 2.3. Infraorbital nerve injuries and accompanied injuries to brain and skull were most common in facial trauma. The incidence of facial trauma increased markedly in the past 3 years, and the injuries tended to be graver and more complicated. The incidence of maxillofacial Injuries caused by traffic accidents rised, the age distribution became younger, and the number of female victims increased more rapidly.
