Authors represented an analysis on 81 patients with traumatic subdural hygromas who had been ad-mitted from 1983 to 1985. All cases were diagnosed by CT scan. The results were summarized as follows: 1).The main symptoms were: headache, lowered consciousness and neurological plateau. Nine patients (8.6%) did not present any symptom. 2)In 81 cases, 43.2% had not associated head injury (simple subdural hygroma), and 54.3% were diagnosed in subacute stage (2 to 14 days). 3)A lot of patients in subacute type subdural hygroma who had contusion or had no associated head injury were getting worse in their clinical course. 4)The most common interval from trauma to diagnosis was from 2 days to 14 days, but in cases with epidural or subdural hematoma, most of subdural hygroma were diagnosed in chronic stage. 5)In cases with surgical treatment, high proportion of patients, who were over 60 years old and whose subdural hygroma were diagnosed in acute stage, showed plateau, or worsened clinical result. In cases with conservative treatment, such a clinical result was noted in lots of patients who had simple and/or subacute type subdural hygroma between 41 to 60 years old. G)Glasgow outcome scale had not relation to interval from trauma to diagnosis of subdural hygroma, but to age of patient and associated head injury. 7)Improvement in CT finding had not relation to type of treatment and clinical result, but to age of patient.
