改良面部损伤严重度评分法评价颌面部创伤1134例

目的 用损伤严重度评分（ISS）法改良后得到的改良面部ISS（revised facial injury severity score,RFISS)法评价1134例颌面部创伤。方法 将急诊入院的1134例颌面部创伤病例依损伤部位分为颌面部单一伤（A组）、颌面部多处伤（B组）两组，用ISS法和RFISS法分析。结果 ISS法和RFISS法都能判别A组与B组伤情严重度，两组比较，差异有非常显著性意义（P＜0．01）。但RFISS更能将伤情严重程度显示出来。另外，在反映损伤处数方面，RFISS法也优于ISS法（P＜0．01）。结论 在颌面部损伤严重度研究中，RFISS法有效，且优于ISS法。

Preliminary study on scoring methods for maxillofacial injury severity

Objective To preliminarily study the scoring methods for maxillofacial injury severity. Methods A total of 1 134 patients with maxillofacial trauma emergently accepted in our hospital were analyzed respectively in this study. The patients were divided into two groups, the single injury group (Group A) and the maxillofacial multiple injury group (Group B). These two groups were analyzed with the Injury Severity Score (ISS) and the Revised Facial Injury Severity Score (RFISS). Results The injury severities between Group A and Group B were significantly different with both ISS and RFISS (P<0.01 ). But RFISS could express injury severity more effectively. Moreover, the injured sites according to RFISS were much more exact than that according to ISS (P<0.01). Conclusions RFISS outperforms ISS as a numerical injury severity identifier in maxillofacial trauma research.
