Surgical Outcome in 435 Patients Who Sustained Missile Head Wounds during the Iran-Iraq War

Abstract

Abstract Variables important in predicting the final postsurgical outcome of 435 patients who sustained missile head wounds during the Iran-Iraq War were evaluated over a 99-month period. The type of projectile, site of injury, and presence or absence of foreign material did not seem to have a significant effect on the final outcome. Of the patients with a perforating type of injury, 48.8% had a poor surgical outcome as compared with 19.9% with a penetrating type and 15.6% with a tangential type. This difference is statistically significant (x2 = 14.7 and 17.1, respectively; p < 0.001). The most important factor in predicting overall outcome was the Glasgow Coma Scale (GCS) score at the time of admission. Mortality and morbidity contributing to a poor surgical outcome were noted in only 6% of patients with a GCS score at admission of 13 to 15, in 24.6% of those with a GCS score of 9 to 12, in 57% of those with a GCS score of 6 to 8, and in 65% of those with a GCS score of 3 to 5. Of the 71 patients who died, 75% had a score of 3 to 8. Perforating projectiles or those traversing two or more dural compartments were statistically significant in contributing to mortality and moribidity (x2 = 17.2; p < 0.001). The incidence of focal neurological deficit was 100, 90.6, 88, and 52.2% in patients with GCS scores of 3 to 5, 6 to 8, 9 to 12, and 13 to 15, respectively, The two best predictors of mortality in this group of patients were a low GCS score and infection.
