    Abstract

    Objective

    Traumatic subdural hygroma (T-SDG) has been generally treated using conservative management rather than surgical methods. This study was performed to evaluate the clinical course of T-SDG with radiologic studies.

    Methods

    A retrospective study was conducted among patients diagnosed with T-SDG from January 2011 to December 2011. The patients were categorized into two groups. Group A has the widest width of T-SDG below 8 mm, Group B more than 8 mm. Computed tomography (CT) and magnetic resonance imaging (MRI) were carried out in both groups.

    Results

    Seventy-four patients were confirmed with T-SDG and were grouped as follows: 44 patients in Group A and 30 patients in Group B. There was no significant difference in age and sex ratio between group A and B. It took more time to resolve T-SDG in Group B (95.2±86.4 days) than Group A (14.4±6.7)(p<0.001). However, no significant difference was observed in the Glasgow Coma Scale (GCS) between the groups. In 10 patients of Group B, T-SDG developed into chronic subdural hematoma and one of these patients underwent surgery.

    Conclusion

    Most T-SDGs were resolved after some period in this study. Surgery does not seem to be necessary in resolving T-SDG.
