ABSTRACT
OBJECTIVE: To make clear the range of firearm wound in the maxillofacial region, the optical repair time and the characteristics of accompanied indirect brain damage, and to offer the principle of emergency treatment and the early repair of war wound. METHODS: With the aid of the standard Sweden model, 200 dogs were used in the experiment. Varies tissues around the primary canal were harvested chronologically, in different zone and different tissue, for histopathological examination. RESULTS: The necrotic range of various tissues in the maxillofacial region was less than that in the extremities. In the maxillofacial region, there was a significant temporary cavity following the passing of bullet, which caused indirect brain damages. CONCLUSION: These findings are helpful to the treatment of war wound in the maxillofacial region. Early bone transplantation using microvascular anastomosis in the treatment of gunshot wound in the maxillofacial region is recommendable.
