Abstract
Introduction: Chronic subdural hematoma is one of the most frequent problems in neurosurgical practice. There are several procedures for the treatment of this entity. While burr hole with continuous drainage is the most often used technique, there are no sufficient evidences of the number of burr hole in respect to the results and complications.
Objective: To compare the results of single and double burr holes for the treatment of unilateral chronic subdural hematoma
Methods: 115 patients with chronic subdural hematoma were surgically treated with burr hole craniostomy in Buriram hospital from February 2006 to January 2010 were analyzed retrospectively. All patients underwent irrigation and placement of closed-drainage system. Good outcome (GOS 5), recurrence, hospitalization days, mortality and complications were compared.
Results: Fifty five (47.8%) patients treated with single burr hole were compared to 60 (52.2%) patients treated with double burr holes. There are no statistical significant difference in good outcome, recurrence, hospitalization days, and mortality (p > 0.05).
Conclusions: The number of burr holes does not affect the post-operative outcomes, recurrence rate, hospitalization days, and mortality of chronic subdural hematoma.
Key words: Chronic subdural hematoma, Burr hole drainage, Recurrence
