Abstract :

Objective: Chronic subdural hematoma (CSDH) commonly recurs after surgery and Burr hole Drainage (BHD) is the commonest procedure for its treatment. Number of burr holes may have beå on the recurrence rate of CSDH. Materials and Methods: A prospective randomized study to investigate the effect of number of burr holes on the recurrence rate of CSDH was undertaken. During the study period, 170 patients were enrolled for the study, and randomized using Random allocation software, but only 140 patients completed the study. 70 patients were in “Single BHD” group (Single burr hole made) and 70 patients were in “Double BHD” group (Double burr hole made). The primary end point was symptomatic recurrence needing re–drainage up–to a period of 6 month. Results: Recurrence occurred in 11 patients in “Single BHD” group, and 7 patients in “Double BHD” group (p = 0.456). The medical and surgical complications were comparable between the two study groups. Conclusion: Single burr hole is as effective as Double burr hole for CSDH treatment and is less time consuming and less morbid to the patient.
