ABSTRACT
The authors have presented 44 cases of chronic subdural hematoma which were diagnosed by brain computerized tomographic (CT) scan at the Department of Neurosugery, Keimyung University, School of Medicine from May 1980 to July 1982. There were 42 men and 2 women. The common incidence of age was between fourth and fifth decade. Most of the cases(80%) had a history of head injury and nearly all cases complained headache(93%). The most common sign was papilledema(71%) in relatively young age patients and mental change(62%) in old age patients. All cases performed brain CT scan, which showed hypodense(41%), isodense(21%), hyperdense(21%) and mixed dense(18%) lesion. The thickness of hematoma which was measured by brain CT scan revealed 10 mm-30mm in most cases and showed the tendency of increase in old age patients. Of 44 cases, 23 cases were treated with craniotomy and membranectomy, 18 cases with burr hole and drainage, and 3 cases which were bilateral lesion with both methods. There was not any different result in both methods and most of all cases showed good postoperative course except 3 cases of poor preoperative state.
