Objective: Chronic subdural hematoma (CSDH) represents one of the most common types of intracranial hemorrhage. This entity has a favorable prognosis when treated properly. Material and Method: We retrospectively reviewed the records of the patients with the diagnosis of CSDH who were treated surgically in our clinic between January - December 2010. Results: The study population consisted of 41 patients (27 males and 14 females). Mean age was 65.1±18.4 (13-91 years). Twenty-six patients (63 %) were over 65 years. The major symptoms were headache (41 %) and extremity weakness (36 %). A history of trauma was present in 22 patients (53 %) and 46 % of patients also had history of chronic illness. Forty patients were treated with single or double burr-hole craniostomy. Complications developed in five patients (pons bleeding, subarachnoid haemorrhage and seizure, epidural hemorrhage at the contralateral site, intracerebral hemorrhage and meningitis). Discussion: Burr-hole craniostomy for chronic subdural hemorrhage is a simple and easy treatment method with lower complication rates.
