Penetrating head injuries caused by a new weapon, the side dome.

The "side dome" is a mix of high and low explosives with a multitude of small metal balls molded within a specially designed half-sphere that directs the explosion wave and the projectiles in one direction to augment the harm. This weapon, originally designed by guerrilla and terrorist groups, is now used by regular armies. This report presents one craniocervical and eight cranial injuries caused by this new weapon and discusses the cases' various clinical features, the paucity of intracerebral cavitation damage along the missile track, the need for only minimally aggressive surgery, and the relatively favorable outcome. In all cases, the helmet offered good protection and the entry of the projectiles was just below its rim in an upward direction.
