  • 1Department of Neurosurgery, Wonju College of Medicine, Yonsei University, Wonju, Korea.


A retrospective analysis of 60 patients with traumatic subdural hygroma who had been managed and followed up at least 6 months, was done in relation to time of development and associated intracranial lesion, initial Glasgow Coma Scale(GCS), sequeritial changes of subdural hygroma, and Glasgow Outcome Scale(GOS). The incidence of traumatic subdural hygroma was 8.4%, 131 cases among 1,563 head-injured cases. And most of them was subacute from(55%, 33 cases among 60 cases), complex subdural hygroma was 65%(39 cases among 60 cases). The conversion rate of traumatic subdural hygroma into chronic subdural hematoma was 15%(9 cases among 60 cases). There was no statistically significant relation between initial GCS score and time of development and also intial GCS score and development of complex subdural hygroma and time of development and GOS of 6 months follow-up(P>0.05). There noted only highly significant relation between initial GCS score and GOS of 6 months follow-up(P<0.001).
