Background: The aim of this study was to develop a tool which can be used to do a collaborative and prospective survey on the epidemiologic characteristics, treatment and outcome of maxillofacial trauma in China and to ameliorate the existing score and treatment methods of maxillofacial trauma.Methods: Chinese Maxillofacial Trauma Registry, Analysis and Injury Severity Score System were developed. Functional modules of this system include clinical data, user management, data inspection, data retrieval, statistic analysis, follow-up survey, injury severity score, system maintenance. The Client/Server and Browser/Server database structure were applied to achieve telematic. The Abbreviated Injury Scale code rules of facial region were revised in detail to embody the characteristics of maxillofacial trauma. Maxillofacial Injury Severity Score (MISS) was designed to evaluate the severity of function derangement in maxillofacial trauma. Thousand nine hundred fifty-nine patients with facial injuries were classified into different groups by the number of fractures and site of injuries. The severity of different groups were evaluated with Injury Severity Score (ISS), Revised Facial Injury Severity Score (RFISS) and MISS, respectively. The results of ISS, RFISS, and MISS were statistically analyzed.Results: By distributed applying of the system, the survey networks of Chinese maxillofacial trauma had been founded. The classification of trauma etiology, injury type, and severity were meliorated. With the help of the system, the input, management, retrieval and statistically analysis of maxillofacial trauma data can be conveniently and accurately accomplished. Furthermore, the ISS, RFISS, and MISS can be automatically calculated and analyzed according to the code rules of Abbreviated Injury Scale and Revised Abbreviated Maxillofacial Injury Scale.Conclusion: The system has satisfactory stability, security, compatibility, and specialty. It can be used to collect standard cases of maxillofacial trauma and to do a collaborative research on the epidemiologic characteristics, treatment, and outcome of facial injuries. MISS is more accurate, objective, and credible than ISS and RFISS in reflecting the severity of maxillofacial trauma and evaluating the curative effect and prognosis.
