Comparative correspondence analysis of the results obtained with two expert approaches for quantitative evaluation of injuries at maxillofacial region
Summary. The current problem of the expert approaches for maxillofacial injuries assessment based on the different level of their inconsistency with each other, taking into account the differences in the methodology of their implementation.
The aim of the study – to provide comparative analysis of the results obtained with the use of two expert approaches FISS (Facial Injury Severity Scale) and MFISS (Maxillofacial Injury Severity Score) during quantitative assessment of maxillofacial injuries cases.
Materials and Methods. In order to achieve the aim of the study, research was conducted with the participation of 14 patients, who were diagnosed with injuries of the maxillofacial area characterized by varying severity degree. Quantitative assessment of injuries at maxillofacial area was performed using two expert approaches FISS and MFISS. During statistical processing of the results, the average values of the studied indicators and levels of standard errors were obtained, the level of correlation between the studied and the derived values was determined, and the authenticity of the identified discrepancies was checked.
Results and Discussion. The correspondence analysis of the results obtained with the use of two expert approaches FISS and MFISS during quantitative assessment of maxillofacial injuries cases found out that the level of correlation between the obtained indicators among patients in the study group was r=0,65 (p<0,05), with the correlation between FISS and hospitalization duration equal to r=0,71 (p<0,05) and between MFISS and hospitalization duration equal to r=0,78 (p<0.05).
Conclusions. Considering the established level of correlation between the MFISS and FISS outcome values, and the fact that there is a correlation between the results of traumatic jaw injuries evaluation and the hospitalization duration, it is possible to summarize the feasibility of further studies aimed at unification of diagnostic algorithm of injured persons in the structure of a comprehensive prediction of future rehabilitation effectiveness and trends corresponding potential level of dental health loss.
