High-energy ballistic and avulsive facial injuries: classification, patterns, and an algorithm for primary reconstruction.

A 17-year experience from 1977 to 1993 with gunshot, shotgun, and high-energy avulsive facial injuries emphasizes the superiority and safety of "ballistic wound" surgical management: (1) immediate stabilization in anatomic position of existing bone, (2) primary closure of existing soft tissue, (3) periodic "second look" serial debridement procedures, and (4) definitive early reconstruction of soft-tissue and bony defects. The series contains 250 gunshot wounds, 53 close-range shotgun wounds, and 15 high-energy avulsive facial injuries. Four general patterns of involvement are noted for both gunshot and shotgun wounds and three for avulsive facial injuries. The treatment algorithm begins with identifying zones of injury and loss for both soft and hard tissue. Gunshot wounds are best classified by the location of the exit wound; shotgun and avulsive facial wounds are classified according to the zone of soft-tissue and bone loss. Treatment, prognosis, and complications vary according to four patterns of gunshot wounds and four patterns of shotgun wounds. Avulsive wounds have not been recommended previously for ballistic wound surgical management. The appropriate management of high-energy avulsive and ballistic facial injuries is best approached by an aggressive treatment program emphasizing initial primary repair of existing tissue, serial conservative debridement, and early definitive reconstruction.
