During 3 years (1967-1970), we observed on simple skull radiograms of 1110 cases of head injury patients, someof cases was performed the pneumoencephalography, vertebral and carotid angiography after routine skull series,and compared with the operative findings of it. The results obtained were as follows; 1) Fractures of the skullvault were most frequent, facial bone fracture was next and the least was basilar fracture. 2) Among total skullfracture cases, intracranial complications were higher in frequency, epidural hematoma in total cases of headtrauma was 2.9% and subdural hematoma was 2.8%. Without combined cranial fracture the cases of intracranialcomplication of 22% observed. In other complications, intracerebral hemorrhage of 4 cases, subarachnoidhemorrhage,subdural hygroma of 5 cases and etc. were observed. 3) Cerebral angiographic findings were agree with opeativefindings in cases of 94%. 4) The fatal cases were 8.4% and combined cranial fracture of it was 86% including 82.5%of cranial valt fracture. The intracranial complications were 86.6% in fatal 52 cases proceed to angingraphy andsubdural hematoma observed on cases of 24.7% of it.
