ABSTRACT
Aim: Quantitative evaluation of prognostic correspondence between initial maxillofacial traumatic injury assessed by facial injury severity score and maxillofacial injury severity score, treatment cost and duration of hospitalization among Ukrainian patients. Methods: Design of present study was retrospective and based on the medical data of patients hospitalized with signs of maxillofacial trauma. Quantitative assessment of maxillofacial trauma was held with the use of facial injury severity score (FISS) and maxillofacial injury severity score (MFISS). Average treatment cost and hospitalization duration were used as coordinative criteria for economical treatment-related burden verification. Results: Levels of correlation between FISS, treatment charges and hospitalization duration were r=0.69 (Ñ<0.05) and r=0.67 (Ñ<0.05) respectively, while analogical correlations for MFISS were 0.74 (Ñ<0.05) and 0.69 respectively (Ñ<0.05). Statistical correspondence between FISS and MFISS scores among study sample reached r=0.71 (Ñ<0.05). Cases with milder maxillofacial trauma types, characterized with initial lower levels of FISS and MFISS scores, demonstrated greater degree of FISS-to-MFISS inter-relation compare to cases with severe maxillofacial trauma. Conclusion:Even though FISS and MFISS scores both demonstrated reliable levels of correlation with hospitalization duration and cost of dental rehabilitation after maxillofacial trauma injury, but MFISS approach characterized by prognostically greater level of statistical relationship with economically related treatment derivates. Moreover, differentiation capabilities of MFISS is relative greater than FISS, since independent grading of separate functional disabilities becomes possible
