In our population posttraumatic epilepsy did not bear a significant relationship to mortality, as shown in Table 7 of our study.2 Possible explanations for this difference include population differences, epochal differences, and a course of 25 years of medical progress in the management of penetrating head injuries.Our population (1,132 patients) was a large representative sample of patients with penetrating head injuries reported on a standard head injury registry form by various neurosurgeons in
