The authors analysed 59 cases of chronic subdural hematomas which were treated surgically at the Department of Neurosurgery, Ulsan Dong Gang Hospital from Janua~y 1989 to august 1993. AU hematomas were operated on by burr hole trephination and continuous closed-system catheter drainage as a safe, less invasive, and efficacious method Male was predominant to female with the ratio 3.9 : 1 and the peak incidence was 3-60 years ago. Most of the cases had a history of head injury(75%). The patients were graded according to the scale proposed by Marbalder et al and 87% were in Grade 1 and 2 The major clinical systoms and signs were headache(80% >, consciousness deterioration(57 % >, motor weakness(48% >, papilledema (25%).The hematoma densities shown on Brain CT Scan were iso, hypo, and hyperdense in order of frequency. Among the patients a history of chronic alcoholism were presented in 38 46, but we failed to identify any sigmfkant differences in clinical analysis between alcoholism group and non-alcoholism group. We have found that the preoperative neurological state was the most realiable prognostic factor.
