Studies on cranial gunshot injuries in the Syrian war are present in the literature. However, the effect of surgical timing on the clinical outcomes of patients undergoing surgical treatment has not been discussed extensively. In this study, the time from injury to surgery is called "time to surgery." Kilis, a city close to Aleppo, Afrin, and Azez, where the conflicts in Syria are intense, is one of the cities where the first emergency treatments were administered. This study aimed to evaluate patients who underwent surgery in Kilis State Hospital due to cranial gunshot injury in the Syrian war and to investigate the effect of surgical timing on mortality and Glasgow Outcome Score.Surgical treatment was applied to 42 (32.8%) patients in the first 4 hours, 64 (50%) patients within 4 to 24 hours, and 22 (17.2%) patients between 24 hours and 3 days. As the time to surgery decreased, the good Glasgow Outcome Score (GOS) (4-5) outcome rates increased. The differences in surgical timing and GOS results of patients with Glasgow Coma Score (GCS) <8 and >8 were found to be significant for good GOS results. As the time to surgery decreased for patients with a GCS <8 and >8, mortality rates decreased equally. This result was statistically significant.Our study showed that surgical timing is as important as early intubation, aggressive resuscitation, and admission GCS for both survey and GOS.
