Abstract
The aim of this study was to determine the subdural haematoma recurrence rate in patients with symptomatic chronic subdural haematomas (CSDH) treated with either burr hole trephination (BHT) or minicraniotomy (MC) and to determine whether a statistically significant difference exists between the two techniques. A retrospective analysis of all consecutive patients with symptomatic CSDH treated with BHT or MC at the John Hunter Hospital Neurosurgery Department between July 2004 and July 2016 was performed. After inclusion/exclusion criteria were applied, 368 patients with 439 CSDHs were eligible. Baseline demographic data was recorded for all patients. Statistical analysis was performed assessing haematoma recurrence as the primary outcome and mortality as a secondary outcome. Three hundred and sixty eight patients were included in the study, with 225 being treated with MC and 143 with BHT. Baseline demographic data was similar between the two groups. The recurrence rate for patients treated with BHT was 0.13 (95% CI 0.08-0.18), versus 0.18 (95% CI 0.13-0.23) in the MC group. This difference was not statistically significant. Similarly, there was no statistically significant difference in mortality rates between the two groups. The mortality rate in the BHT group was 0.09 (95% CI 0.05-0.14) versus 0.09 (95% CI 0.05-0.13) in the MC group. In our series there was no difference in recurrence rates or mortality rates between the two groups, suggesting MC is an effective alternative to BHT in the management of symptomatic CSDH.
