Traumatic brain injury (TBI) occurs when the brain is damaged as a result of physical trauma. TBI may be caused by a penetrating (open) head injury, in which an object pierces the skull and enters the brain tissue, or a closed head injury, in which the skull is not breached, and frequently results in the major long-term disability of individuals surviving head injuries.(7) Cranial firearm wounds often result in severe injury to the brain and related central nervous system (CNS) structures.(18). Although penetrating head trauma is less prevalent than closed head trauma, PBI carries a worse prognosis with high morbidity and mortality rates. Understanding of the mechanisms of injury and aggressive medical management with rapid surgical intervention may lead to improved outcomes
