Craniofacial Fractures: Proposal of a new scoring scoring system

Objectives: The complexity of facial fractures has significantly changed in recent years in keeping with more commonly observed high velocity trauma. Traditional classification systems describe fractures in an isolated manner but failed to recognise fractures affecting more than one region. This study applies four conceptual craniofacial trauma scoring systems to a cohort of trauma patients seen in East London. We exposed the limitations of these systems and developed new scoring system capable of overcoming previous limitations.

Materials and methods: We applied four previously validated conceptual models to a defined trauma population of 119 patients. 5 observers assessed the total number of cases against the gold standard which was a Consultant Oral and Maxillofacial Surgeon. Inter and Intra observer variance was analysed and correlated to mechanism of injury. We observed the merits and pitfalls of each model and developed a new model ZS avoiding previously noted limitations.

Results: All four models demonstrated similar trends with respect to the severity of the injury. The mean score for each patient was 17 (SD 20.4 range 0-118). The ZS score had strong intra-class correlation with an inter observer score of 0.98 and intra observer score of 0.99 (p<0.0001).

Conclusion: The newly created ZS model appeared valid with respect to observer variance and performance. It does allow classification of the more complex injuries. Although the potential appears great further studies are required to analyse the impact of such system on operating time, patient mobidity. hospital instay, treatment costs
