Relationship between Decompressive Craniectomy and Traumatic Brain Injury Outcomes: A Single-Center Study

Traumatic Brain Injury (TBI) has significantly increased both mortality and morbidity in developed and developing countries. Decompressive Craniectomy (DC) is an option when conventional treatments fail to reduce intracranial pressure (ICP) when brain edema occurs in TBI. This study aims to determine the relationship between DC and patients with TBI in West Nusa Tenggara Provincial Hospital whose outcome was assessed with Glasgow Outcome Scale Extended (GOSE) and modified Rankin Scale (mRS). A total of 41 TBI patients who underwent DC were included in the study. Univariate analysis revealed that men made up the majority of the subjects, with 26 people (63.4%) compared to 15 women (36.3%). Traffic accidents (82.9%), falling (12.2%), and being crushed (4.9%) accounted for the majority of the causes of TBI. Bivariate analysis showed that pupillary reflex, length of stay, and Glasgow Coma Scale at discharge from the hospital were associated with outcome (p=0.002; p=0.000; p=0.000 respectively), GOSE (p=0.001; p=0.000; p=0.000 respectively), and mRS (p=0.001; p=0.000; p=0.000 respectively). Other factors such as gender, age, trauma mechanism, GCS admission, and operation time, however, did not significantly affect the outcome, GOSE, or mRS.
