【摘要】 目的　拟建立统一的具有专科特性的颌面部创伤严重度评分标准 ,为进一步对伤度分级提供基础。方法　在AIS 90的基础上 ,增加临床高发的颌面创伤诊断条目 ,将张口受限、咬合关系紊乱、颜面畸形 3个主要病症列入评分指标 ,规定伤度参数 ,得出颌面创伤严重度评分 (MTSS)并进行统计分析。结果　单纯上颌骨、下颌骨、颧骨颧弓、上下颌骨或颧骨复合骨折以及软组织伤各组之间平均评分差异有显著性。MTSS为住院费用及住院天数的显著影响因素。结论　本口腔颌面创伤严重度评分公式可以预测其治疗时医疗资源的消耗 ,对反映口腔颌面创伤的程度具有可信性、灵敏性和特异性。更多还原

【Abstract】 Objective A new injury severity score system was proposed in this study to evaluate maxillofacial injuries.Methods Based on AIS 90,all clinical samples were given diagnosis.Their month opening limitation,malocclusion and facial deformity were recorded as indices in scoring system.Severity injury scores for different groups and types were statistically.analyzed. Results It was demonstrated that there was a significant difference in scores between injuries of soft tissue and bone tissue and between different fracture groups.Conclusions The proposed scoring was system useful to predict the cost of medical care and the days of in patient,relialle,sensitive and speeific in evaluation the maxillofacial injury severity.更多还原
