Chronic subdural hematomas: single or double burr hole-results of a randomized study.

AIM To analyze the analysis of recurrence rates of single versus double burr holes in patients with subacute and chronic subdural hematomas. MATERIAL AND METHODS The study was a prospective randomized controlled trial on patients with subacute and chronic subdural hematomas. Collections with membranes or septae were excluded from the study. A written consent was taken from the patient or patient party after explaining the procedure. A total of 254 patients were enrolled in the study over a period of 18-months in the Department of Neurosurgery, Sheri-Kashmir-Institute of Medical Sciences, Srinagar, Kashmir. RESULTS Recurrence rates in single and double-burr-hole groups were 6.15% and 4.83% respectively, which was not statistically significant. CONCLUSION Most of the subdural hematomas can be dealt by single burr-hole drainage.
