INTRODUCTION: Maxillofacial fracture is the most common trauma that happened in the developing countries. One of the methods to evaluate the severity of maxillofacial fracture is by using the Facial Injury Severity Scale (FISS) score. Maxillofacial trauma causes multiple injuries, thus resulted in various periods of hospitalization. AIM: The aim of this study is to use the employment of the FISS score to predict a patient’s length of stay. METHODS: This research was a retrospective cohort and cross-sectional study on maxillofacial fracture patients whom treated in Sanglah General Hospital, Denpasar, Bali. As much as 89 subjects were included in this study and information about their age, gender, mechanism of injury, FISS score, treatments, and length of stay was collected. The data were statistically analyzed using bivariate, receiver operating characteristics (ROC), and linear regression analysis. RESULTS: A total of 89 subjects were included in this study. Among them, 50 subjects had a high FISS score, and 39 subjects had low FISS score. The average age was 28.9 ± 13.3 years with a mean length of stay 6.39 ± 4.29 days. Bivariate analysis showed that the patients with high FISS score have 5.3 times higher risk to get a longer length of stay compared to those with low FISS score (95% CI: 2.289–12.289; p = 0.001). The mean of length of stay in subjects with a high FISS score was significantly higher compared to subjects with a low FISS score (mean for subjects with high score: 8.46 ± 4.63; mean for subjects with low score: 3.74 ± 1.46; p = 0.001) with a correlation value r = 0.718 (p = 0.001). ROC analysis represented that FISS score ˂4 was categorized as mild. The linear regression analysis showed that the length of stay for maxillofacial fracture patients was able to be predicted by LOS = 1.476 + 1.032 × FISS score. CONCLUSION: The FISS score can predict the length of stay for patients with maxillofacial fracture.
