Head injury is a significant economic, social and medical problem in the United States. For this reason, prognostic factors in head injury are of major importance to all surgeons who treat severely injured patients. Outcome of severe head injury is frequently determined at the time of impact, and surgical and medical treatment is often ineffective. ⋯ Multimodality evoked responses are a noninvasive prognostic technique which predicts outcome with a high degree of certainty. For optimal accuracy, prognosis should be based upon a combination of factors, including age, Glasgow coma score, pupillary response, eye movements, presence of surgical lesion, motor posturing and multimodality evoked responses. Decisions regarding surgical and medical treatment of patients with head injury should be based upon these prognostic factors.
