Comparison of One vs. Two Burr Hole Craniostomy in Chronic Subdural Hematoma Recurrence

Introduction/Objective:  Chronic subdural hematoma (CSDH) is most frequent neurosurgical conditions. To find the recurrence rate of chronic subdural hematoma in patients who underwent one vs. two burr craniostomy. Material And Methods:  A randomized controlled trial was conducted at the Neurosurgery department, Ayub Teaching Hospital, Abbottabad. In the current study, a total of 76 (38 in each group) patients were observed. ASA-I, ASA-II, ASA III patients, symptomatic radiologically proven Chronic subdural hematoma. Patients were randomly allocated into two groups of 38 patients each. randomization with blocks. Group A was treated with intraoperative epidural methylprednisolone while Group B was treated with normal saline only. Clinical information was recorded on a pre-designed proforma. Results:  Mean age was 54 years in group A, and 56 years in group B. In group A, 74% were male and 26% of patients were female. In Group B, 76% were male and 24% were female. The group A, 5% of patients had recurrence while in Group B, 13% of patients had a recurrence. There existed a significant difference between effectiveness and not-effectiveness of one/two burr hole craniostomy among patients who were less than 40 years. Conclusion:  The recurrence rate of chronic subdural hematoma is higher in patients undergoing two burr hole craniostomy as compared to one burr craniostomy.
