The Retrospective Study Of1022Patients With Maxillofacial Fractures

Objective：To evaluate epidemiologieal features of maxillofacial fracture in thedepartment of oral and maxillofacial surgery in the StomatologicalHospital of Jilin University from2009to2014. Descrip theepidemiologieal information including the gender, age, occupation, timedistribution of injury, cause of injury, pattern of fractures, treatments andcomplications.Methods：We took a retrospective study on a total of1022patients withmaxillofacial fracture treated in Jilin university hospital from2009to2014. Data regarding age, gender, occupation, cause of injury, type offracture and nerve injury, and associated systemic injuries were reviewed.Results：1022patients were treated and reviewed from2009to2014. Themale to famale ratio of the patients was3.69:1and69.38%of patienswere aged between20-49years. The leading cause of injury was trafficaceident(37.97%). The incidence of maxillofacial injuries was highest insummer, and lowest in winter. Multiple fractures(67.91%) had higherprevelance than single fracture. The average number of fraetures foreach patient was2.43. The mandibular fraetures(37.77%) was mostfrequently seen, followed by the zgomatic fraetures(37.00%) and maxillafraetures(21.19%). The most common site of the mandibular fracture was the symphysis of mandible(36.19%). The most commom site of thezgomatic fraetures was the zygomatic arch(37.70%). The most commontreatment is rigid iniernal fixation with plate. Limb damage(14.12%) wasthe most common associated systemic injuries. The patient’s generalcondition can not be neglected during the treatment.Conclusion：1.The majority of maxillofacial injuries were found in males, and themost prevalent age ranged from20-49. The incidence of maxillofacialinjuries occur most in summer. The most common cause of injury wastraffic accident.2.The multiply fractures had higher prevelance in maxillofacialinjuries. The mandibular fraetures was most frequently found, followedby the zgomatic fraetures and maxilla. The most common treatment isrigid internal fixation with plate during fourty-eight hours and two weeksafter injury.3.Soft tissue injuries, tooth injuries and nerve injuries are the mostcommon facial injury complications.4.The most common associated systemic injuries are limb injuries,brain injuries and eye injuries.
