In modern society, characterized by variability of daily life, complicated industrial structure and suprizingly increased traffics, the danger of unexpected accident is always threatening the people. About two thirds of traffic accident patient have head injury of various forms.
A clinical analysis was carried out with 550 cases of craniocerebral injuries observed at the department of neurosurgery, Chungnam National University Hospital in 4 years
between June 1973 and July 1976.
The results were as follows:
1. There were 418 men 132 wonmen:male female ratio was 3 : 1.
2. The commonest cause of head injury was traffic accident (53. 5% of total patient) and the next was "falls" (22. 3% ).
3. In skull fractures, vault fractures were 85.8%, basal skull fracdures 14.2%. The incidence of simple fractures was higher that of compound fractures, the ratio being 9.4. Most of liner fratures were simple fractures.
4. Among the intracranial hemorrhagic lesions, subdural hematoma occupied about half of the total cases, most of them were acute cases.
The epidural hematoma, the predilection site was temporal area, occupied about 26.70 of total intracranial hemorrhagic lesions. The intracerebral hematom3 occurred predomina-ntly in temporal lobe.
5. About 56.9% of the patients with intracranial hemorrhagic lesions were accompanied by skull fracture while 30.2% of the patient having skull fracture presented intracranial hemorrhagic lesions.
6. The level of consciouseness on admission was altered in about 80% of the total pati-ents vomiting occured in 22.2% of total patients and early convulsive attacks were notice in 5. 1%.
7. Overall mortality rate of all the head injurry patient was 10. 4% and their operative rate was 30. 3%. The mortality rate in severe cerebral contusion was 41.9%.
8. Sequalae were noticed in about 38.5% of the total patients. The most frequent one was postconcussional syndrome the incidence being 29% of the total patients.
9. Associated injuries were found in about 11. 3% of the total patients. The frequent one were mandible and/or teeth, femur and rib in order.
