Beyond facial injury: prognostic utility of maxillofacial trauma scores in the emergency department.

PURPOSE: To evaluate the prognostic utility of two widely used maxillofacial trauma scoring systems (MFTSs) -the Facial Injury Severity Score (FISS) and Maxillofacial Injury Severity Score (MFISS)- in adult multiple trauma patients in the emergency department (ED).

METHODS

This prospective observational study was conducted in the ED of a tertiary care hospital between 01.08.2020 and 01.08.2021. A total of 124 MFT patients aged ≥ 18 years with at least one concomitant injury to another organ system were included. FISS and MFISS were calculated for each patient. The associations between scores and coexisting injuries, intensive care unit (ICU) admission, and mortality were analyzed. Predictive performance for mortality was assessed using receiver operating characteristic (ROC) curve analysis.

RESULTS

Higher FISS scores were significantly associated with intracranial injuries, including subarachnoid hemorrhage (SAH), cranial fractures, and pneumocephalus (all p < 0.01), as well as with pneumothorax, rib fractures, ICU admission, and mortality (all p ≤ 0.004). MFISS scores were significantly higher in patients with SAH, while a negative association was observed between MFISS and abdominal injuries (p = 0.043). ROC analysis demonstrated good predictive performance for mortality, with areas under the curve of 0.820 for FISS and 0.758 for MFISS (both p < 0.01).

CONCLUSIONS

FISS and MFISS are associated with clinically meaningful outcomes and may serve as practical tools for early risk stratification and prognostic assessment in the ED among adult multiple trauma patients with maxillofacial injuries.
