Penetrating trauma to the head.

Penetrating trauma to the brain is not as common as blunt trauma; however, the incidence is becoming a frequent occurrence in our society. Rapid transport to trauma centers where definitive care can be rendered is essential. Outcome depends on the site of the missile tract, the presenting neurologic status, and the extent of neurologic tissue destruction. Neurologic deterioration occurs rapidly, and outcome results seem to depend on the patient's neurologic status at the time of surgery. CT scanning is the diagnostic procedure of choice and should be performed if the patient's condition is stable (see Fig. 3). Aggressive removal of missile and bone fragments needs to be balanced by the knowledge that it is preferable to leave behind a few hard-to-reach fragments than to increase the patient's neurologic deficit. CT scanning in the postoperative period is very helpful in identifying abscess formation as well as new or recurrent hematomas, edema, and areas of tissue injury not evident at the time of initial scanning. Antibiotic therapy should be initiated preoperatively. Control of elevated ICP plays a significant role in decreasing mortality and morbidity. Judicious debridement of injured brain combined with medical management of increased ICP will maximize the quality of recovery and increase survivability. Although great strides have been made in reducing mortality and morbidity for trauma patients, the sad issue is that the majority of traumas are preventable. Until society is willing to understand that it needs to make firearm safety a priority, there will always be patients to care for who have sustained a penetrating injury.
