目的 建立颌面部损伤严重度定级分类法 (maxillofacialinjuryseverityscaleclassifica tion ,MISSC)。 方法 回顾性研究 170 2例连续性颌面部损伤住院病人资料 ,依据伤情划定损伤程度为轻、中、重三种。采用AIS - 90版对各项损伤量化记分后 ,作因子分析及逐步判别分析 ,得到颌面部损伤严重程度评分分类函数 ,并进行回顾性、刀切法及前瞻性检验。 结果 因子分析将各类具有共线性的原始数据归类 ,得出的因子具有专科意义。逐步判别分析所得的分类函数 ,各项检验准确率均很高 :回顾性考核为 91.8% ,刀切法为 91.5 % ,前瞻性考核为 90 .1%。其中 ,前瞻性考核的灵敏度分别为 0 .92 2 (轻 )、0 .90 2 (中 )、0 .818(重 ) ,特异度分别为 0 .92 7(轻 )、0 .891(中 )、0 .995(重 )。 结论 MISSC法判别颌面部损伤的严重程度准确 ,漏判、误判率低 ,可用于临床伤情的分析研究。
Objective To establish the maxillofacialinjury severity classification (MISSC). Methods A retrospective study of 1702 cases of continuous maxillofacial injury inpatients, according to the injury delineated the degree of injury as light, medium and heavy three. The AIS - 90 version was used to scoring the scores of each lesion for factor analysis and stepwise discriminant analysis to get the classification function of maxillofacial injury severity. The retrospective, knife - cutting and prospective tests were performed. Results Factor analysis categorizes all kinds of raw data with collinearity, and the obtained factors are of special significance. Stepwise discriminant analysis of the classification function, the test accuracy are high: a retrospective assessment was 91.8%, knife-cut method was 91.5%, prospective assessment was 90.1%. Among them, the sensitivity of prospective examination was 0.92 2 (light), 0.90 2 (medium), 0. 818 (weight), the specificity was 0.92 7 (light), 0.891 (medium) , 0 .995 (weight). Conclusion The MISSC method can be used to judge the severity of maxillofacial injury accurately, with missed judgment and low false positive rate. It can be used in the analysis of clinical injury.
