[An experimental study of injury characteristics in maxillofacial region following different kinds of high velocity projectiles wound].
Model 7.62 mm, model 5.56 mm bullets and 1.03 g steel sphere, 1.0 g fragment with impacting velocities 1300-1400 m/s were used to shot soap target, mandibular area of pigs in vitro and dogs in vivo. The shape and size of cavitations and wounds were observed and the specimens of wounded muscles were collected for light and electron microscopic observation. The authors found that different kinds of cavitations formed in different kinds of projectiles wound, which produced different injured characteristics in maxillofacial firearms wound. The characteristics of maxillofacial wound ballistics and difference of maxillofacial wounds in different kinds of high velocity projectiles wound were also discussed in the article.
