Association between the maxillofacial injury severity score to helmet types, neutrophil lymphocyte ratio and length of stay.

BACKGROUND

Traffic accidents are a major etiological factor in maxillofacial injuries, exhibiting a high incidence rate. The Maxillofacial Injury Severity Score (MFISS) is utilized to assess the severity of maxillofacial trauma. Helmet use is a preventive measure against more serious injuries. Patients with maxillofacial trauma are at risk of complications and infections. Elevated neutrophil to lymphocyte ratio (NLR) in hospitalized patients correlates with a longer length of stay (LOS).

OBJECTIVES

This study aimed to evaluate the relationship between helmet types and MFISS scores, as well as the relationship between MFISS scores and both LOS and NLR values in patients.

METHODS

An analytical observational study with a prospective design was conducted at RSUP Prof. dr. I.G.N.G. Ngoerah, Denpasar, from March to December 2024. The study sample consisted of 66 trauma patients with maxillofacial injuries, selected based on inclusion and exclusion criteria. Data were analyzed using the Kruskal-Wallis and Spearman tests to assess the relationships between variables.

RESULTS

The Kruskal-Wallis test revealed a positive value of 39.825 with P = 0.000, indicating a significant relationship between helmet types and MFISS scores. Spearman analysis showed P = 0.027 (r = 0.273), demonstrating a significant positive correlation between MFISS scores and NLR values, and P = 0.000 (r = 0.505), indicating a significant positive correlation between MFISS scores and LOS.

CONCLUSION

There is a significant relationship between MFISS scores and helmet types, as well as a significant relationship between MFISS scores and NLR values and LOS in maxillofacial injury patients at RSUP Prof. dr. I.G.N.G Ngoerah.
