Abstract:

This study, using controlled conditions, was designed to provide new data on potential wound morphology from high velocity projectiles of varying sizes by using simulants for human maxillofacial hard and soft tissues. The validity of studying wound morphology in gelatin blocks has again recently been substantiated by Dubin who in 1974 showed that there were remarkable similarities between gelatin and freshly excised pig tissues. The data generated in this study will answer the following questions and provide a more meaningful base on which to improve and develop effective diagnostic procedures, surgical techniques, and enhance total patient care. What are the effects of high velocity variable size projectiles on the human maxillofacial complex What is the morphology of wounds created at these very high energy levels Are current diagnostic and surgical techniques adequate to provide optimum care for injuries caused by varying sized projectiles impacted at speeds in excess of 1,750 ms 5250 fps Will the induced morphology necessitate modifications of existing surgical techniques or must new ones be developed.
