Management of embedded foreign body: penetrating stab wound to the head.

Penetrating craniocerebral trauma is an injury in which a projectile violates the skull but does not exit. The significance of penetrating injuries to the head depends largely on the circumstances of the injury, the velocity of impact, and attributes of the projectile. While most penetrating head injuries are caused by firearms, lower-velocity mechanisms of penetrating brain injury present unique challenges for the multidisciplinary team involved with the delivery of care. Appropriate management can lead to optimal outcomes and limit secondary brain injury.
