Survey Of Epidemiological Characters And Study Of Injury Severity Score Of Maxillofacial Trauma Patients

With the modernization in our country, traffic and industry accidents have increased greatly and been the first public danger. Trauma has heavily threatened our survival quality as the "modern social disease". The government has attached great importance to the prevention and treatment of trauma. It was listed as "national 973 Project". The percent of maxillofacial trauma accounts for about 7%~20% of the trauma in the peace times. The treatment of maxillofacial trauma has been paid more and more attention. The epidemiology study in maxillofacial trauma is less; moreover, demographic and social-economic factors greatly influence the results of the study. The purpose of the present study is to ascertain the epidemiological characteristics and provide detail data of maxillofacial trauma by retrospective study of a large number of clinic data in Xi'an and other areas around it. At the same time, we try to objectively and accurately estimate maxillofacial injury severity. It is significative in diagnosis prevention and restoration ofmaxillofacial injury. The present evaluation method can not effectively evaluate the severity of maxillofacial injury. So we try to probe into a method of maxillofacial injury score according to the specialty of maxillofacial trauma. Besides, we developed our database software and established oral and maxillofacial trauma database in order to evaluate maxillofacial injury objectively and accurately and dynamically.1 Survey of Epidemiological Characters of Maxillofacial InjuriesObjective: To analyse the epidemiological characteristics of maxillofacial injuries. Method: A retrospective review of maxillofacial trauma patients admitted to the Stomatology Hospital of Fourth Military Medical University from January, 1996 to October, 2002 was done. Data were collected on age, sex, etiology and mechanism of injury, location and clinical characters, associated injuries and treatment. Statistic analysis of the data was done. Results: 1159 patients were reviewed. The majority of victims were males. The male: female ratio was 3.95:1. RTA(road traffic accidents)was the major cause of facial injury, 590(59.92%), followed by assault (19.07%), falls(9.66%), Industrial accidents (7.33%).A large proportion of facial injuries occurred on the lower face. The symphysis of mandible was most frequently damaged, followed by condylar. The most common associated trauma was extremity fractures. Conclusion: Prevention and management of maxillofacial trauma in RTA should be strengthened and its characteristics of multiple injuries should be always be anticipated and identified. Further studies in the mechanism and integrative treatment measures of maxillofacial injury should be done.2 Comparison of Three Maxillofacial Injury Severity Score Methods in Evaluation of Maxillofacial TraumaObjective: To design a more reasonable method of evaluating maxillofacial injury severity by retrospective analysis. Method: 984 cases of maxillofacial trauma( <30 days before hospitalization) selected from 1159 cases were grouped by the number of fracture and site of trauma. They were evaluated with ISS, RFISS and MISS respectively. The results of ISS/RFISS/MISS were compared and analyzed with SPSS 11.0 software. Results: MISS could accurately differentiate between single and multiple facial injury. It is more meaningful for evaluating different sites of facial injury than ISS and RFISS. Conclusion: MISS can be used to evaluate maxillofacial injury objectively and accurately.3 The Application and Testing of Maxillofacial Trauma Database SystemObjective: To apply Maxillofacial Trauma Database System and evaluate the scientificalness and practicability of the system. Method: 1159 maxillofacial trauma patients' data admitted to the Stomatology Hospital of Fourth Military Medical University from January, 1996 to October, 2002 were divided in two groups. By applying retrospective and prospective methods, data were inputed in the system, according to age, sex, etiology and mechanism of injury, location and clinical char...
