Association between Comprehensive Facial Injury (CFI) score and Facial Injury Severity Score (FISS) with the severity of maxillofacial injuries - a single centre study

Abstract

Comprehensive Facial Injury (CFI) score is the latest comprehensive and simple scale that can be used to assess maxillofacial injuries. The present study evaluates the use of CFI scores to assess the severity of maxillofacial injuries in terms of length of hospital stay (LOS), the need for surgical intervention, overall surgical time, and the need for support by other specialties. This study was conducted at Hospital Canselor Tuanku Muhriz UKM (HCTM). A total of 280 records of patients diagnosed with maxillofacial injuries and referred to the Oral and Maxillofacial Surgery Department HCTM between the years 2016 to 2021 were reviewed. CFI scores were used to score for every maxillofacial injury. A Pearson correlation was run to determine the relationship between CFI scores and LOS, and overall surgical time. The variables CFI score and LOS were found to be highly positive correlated, r(278)=.65, p<.001. The same result was obtained for the variables CFI score and overall surgical time, where it was found to be highly positive correlated, r(278)=.74, p<.001. A point-biserial correlation was run to determine the relationship between CFI score and the need for surgical intervention, and the need for support by other specialties. There was a very strong positive correlation between CFI score and the need for surgical intervention, which was statistically significant (rpb=.612, n=280, p<.001), while there was a strong positive correlation between CFI score and the need for support by other specialties, which was statistically significant (rpb=.384, n=280, p<.001). CFI scores can be widely used for better communication among clinicians about the severity of the maxillofacial injury and management of facial trauma using a standard classification. It can also use in the clinical setting to facilitate the clinicians to explain the severity of injury to the patient, family members, and administrative staff.
