Abstract : Chronic subdural hematoma (CSDH), an increasingly common neurosurgical disease. The most common procedures for treatment of CSDH include twist drill craniostomy, single or multiple burr hole drainage, and craniotomy. To determine the surgical experiences and outcomes of patients treated by burr hole drainage and mini craniotomy. Patients admitted under department of neurosurgery R L Jalappa hospital and research center requiring surgical drainage of a chronic subdural hematoma from January 2019 to February 2021 were retrospectively reviewed. 40 patients underwent surgery for chronic subdural hematoma. The craniotomy group was comprised of 20. Twenty patients undergoing burr hole washout 6 patients underwent bilateral drainage, in both groups predominantly male were involved, commonest etiology was secondary to remote trauma. 15 patients in the burrhole group and 13 patients in the craniotomy group had a history of being on anticoagulation/anti-platelet therapy. Initial and postoperative mean glasgow coma score and rankin disability scores were found to be very similar in both the groups. Burr hole washout appears to be similar to craniotomy for the treatment of csdh with respect to patient outcome, re-operative rates.
