Background/Objectives:  Chronic subdural hematoma commonly reported in neurosurgical practices. Variations are reported in neurosurgical practices regarding the treatment of chronic subdural hematoma (SDH). This study determined the outcomes of SDH with Drain and without Drain in terms of recurrence and effectiveness.

Material and Methods:  A randomized control trial was conducted in the Department of Neurosurgery Ayub Teaching Hospital Abbottabad. Group-A patients were subjected to drainage of chronic subdural hematoma without drain and Group-B patients were subjected to drainage with drain. All patients were followed up to one month for recurrence of subdural hematoma like on CT-scan.

Results:  Overall, the recurrence of chronic subdural hematoma in both groups was seen in 16.7% of patients and the procedures were effective in 83.3% of patients. In Group A, 79.6% of patients were successfully treated through burr hole with irrigation, while 20.4% of patients had recurrent chronic SDH. In Group B, only 13% of patients had a recurrence, while 87% of patients were successfully treated with burr with the closed continuous drainage system. An insignificant difference (p-value: 0.302) existed between groups for both types of procedures.

Conclusion:  The patients who were treated with burr hole and irrigation of the subdural space with normal saline had high recurrence incidence than those with burr hole with closed continuous drainage system.
