A BSTRACT Introduction: Chronic subdural hematoma (cSDH) is a common neurosurgical condition with various surgical approaches. We compared the outcomes of two standard techniques: keyhole craniotomy and burr hole drainage in a series managed by a single senior surgeon. Methods: This retrospective study reviewed cSDH surgeries at our institution between January 2013 and June 2023. Inclusion criteria were age ≥18 years, available pre- and postoperative imaging, 6-month follow-up, and closed drain placement. We analyzed demographic data, length of hospital stay, modified Rankin Scale (mRS) scores, American Society of Anesthesiologists (ASA) scores, radiological parameters, and recurrence rates. Results: Of 77 patients, 35 met inclusion criteria (14 burr hole and 21 keyhole). Both groups had similar baseline characteristics, including age, sex, preoperative mRS, ASA scores, and radiological parameters ( P > 0.05). Recurrence occurred in three burr hole cases (mean 56 days) and two keyhole cases (mean 30 days) ( P = 0.207). Surgical technique did not significantly affect postoperative mRS improvement ( P = 0.321) or length of hospital stay ( P = 0.448). Conclusion: Consistent with the current literature, this study has demonstrated that burr hole drainage for cSDH yields surgical outcomes similar to the keyhole technique. Considering its shorter operation time and more minimally invasive nature, burr hole drainage can be preferred for the evacuation of cSDHs.
