Abstract:
Objective: To establish an efficient animal model for the study of explosive injury in maxillofacial region.Methods: The detonator, steel spheres as fragments simulants shot by smooth-bore barrel and a synchronizer were used to define the wound model in the maxillofacial region of 18 dogs. The whole system was triggered when shooting. Wounding parameters and the changes of targets after explosion were observed and recorded. Results: The overpressure of blast wave decreased exponentially according to the distance from explosive. After injury, the local damage of dogs was serious and extensive compounded with the damages in heart, lung and brain. The injury was aggravated with the increasing of over pressure and energy absorption. Conclusion: The new wound model can be used for the study of explosive injury in maxillofacial region that is characterized by serious tissue damage and multi-etiology.
