The Severity of maxillofacial trauma in Southern Vietnam: a clinical evaluation of the MFISS and FISS.

Road traffic injuries contribute significantly to mortality and the burden of disease throughout the world, but particularly in development countries. In many developing countries, the majority of those injured in road traffic accidents are pedestrians, cyclists and motorized two-wheel riders.

Maxillofacial trauma forms a considerable part in the overall injuries in traffic accidents. In order to access injury severity and his probable outcome, various trauma scoring systems have been developed over the past decades. The Abbreviated Injury Scale (AIS) became the groundwork of subsequent scoring standards. In two studies conducted separately by Zhang et al and Bagheri et al two new injury severity score systems, the Maxillofacial Injury Severity Score (MFISS) and the Facial Injury Severity Scale (FISS), were developed to evaluate the characteristics of injury from maxillofacial trauma.

The aim of this clinical study is an analysis of maxillofacial injuries transferred and/or referred to the Institute of Odonto-Stomatology HCMC, Vietnam. The MFISS and FISS are evaluated in a clinical setting and compared with each other.

In this epidemiologic study a cohort of patients with MFT transferred and/or referred to the National Hospital of Odonto-Stomatology Ho Chi Minh City (NHOS-HCMC), Vietnam, was analyzed following the MFISS and FISS protocol. This study will give a description of the current situation in Vietnam concerning maxillofacial trauma. The MFISS and FISS are proportionally compared to each other. The MFISS will probably give a more clear representation regarding the extent of the maxillofacial trauma and a greater predictive value regarding the time of the healingproces.
