    BackgroundEpidural hematoma causing brain herniation is a major cause of mortality and morbidity after severe traumatic brain injury, even if surgical treatment is performed quickly. Decompression may be effective in decreasing intracranial pressure, but its effect on outcomes remains unclear.MethodsA retrospective analysis of deeply comatose patients (Glasgow Coma Scale score 3-5) who underwent surgical treatment during a 12-year period, either via osteoplastic craniotomy (OC) or decompressive craniectomy, was carried out. Patient groups were compared on the basis of demographics, admission clinical state, head computed tomography imaging characteristics, and discharge outcome.ResultsA total of 60 patients were examined. The first group of 31 patients (52%) needed decompression during primary surgery. The second group of 29 patients (48%) underwent OC with evacuation of epidural hematoma without decompression. Both patient groups were similar according to age (40.9 ± 13 vs. 40.6 ± 12.5 years), Glasgow Coma Scale score before surgery (4 [3-5] vs. 4 [3-5]), hematoma thickness (based on computed tomography) (3.44 ± 1 vs. 3.36 ± 1.62 cm), and midline shift (1.42 ± 0.83 vs. 1.36 ± 0.9 cm). Mortality was more evident in the decompression group (45.2% vs. 13.8%; P = 0.008), and the Glasgow Outcome Score was also lower, 2.26 ± 1.5 versus 3.45 ± 1.5 (P = 0.003).ConclusionsDecompressive craniectomy following the evacuation of an acute epidural hematoma in deeply comatose patients demonstrated inferior outcomes in comparison with OC. Brain injury in the decompressive craniectomy patient group was more severe (concomitant subdural hematoma, early brain ischemia, and early brain herniation), which may have influenced the outcome. Further prospective studies are needed.Copyright © 2021 Elsevier Inc. All rights reserved.
