Abstract:
Forty-five healthy male dogs were wounded with high or middle-velocity steel ball on the lower part of the face.and the findings were as follows:(1)Craniocerebral injuries concomitant with maxillofacial gunshot wounds were charcterized by brain contusion in the entry side of the temporal lobe and extradural hemorrhage in the entry side of the middle cranial fossa,and their highest incidence and severity were found in those cases with mandible fracture due to high-velocity missiles.(2)The larger the amount of the absorbed energy from the bullet,the higher the incidence and severity of the craniocerebral injury.(3)The incidence and severity of the craniocerebral injury were positively correlated to the value of vibrational acceleration measured on the pareital bones,which suggests that vibrational acceleration plays an important role in the precipitation of craniocerebral injury secondary to maxillofacial gunshot wounds.
