In modern society, among increased number of traumatic brain injury and survived patients are increased due to improvement of acute medical care and neurosurgical procedure. There are any complications that may be often life threatening and delay rehabilitation program, and requires much attention.

This study evaluated the age and six distribution causes of traumatic brain injury, severity by Glasgow Coma Scale, associated injury, and incidence and days when complications detected, The study was done retrospectively through medical record of 305 patients admitted to Soon Chun Hyang University Chunan Hospital, Chunan, Korea between January, 1991 and April, 1992. The results were as follows.

1) The age incidence was high in the first decade(16.7%), 6the decade(15.7%), 3rd decade(14.4%), and 4th decade(14.4%), in order. Male outnumbered female by almost 2.4 to 1.

2) The common causes were traffic accident(71.6%) and falls(21.6%).

3) The incidence of associated injury was 54%

4) The common complications were subdural hygroma(2.3%), hydrocephalus(2.0%), chronic subdural hematoma(2.0%), upper gastrointestinal bleeding(1.3%), seizure(3.0%), and syndrome of inappropriate secretion of antidiuretic hormone(SIADH, 1.6%)

5) The days when complications detected were 39.0 days for subdural hygroma, 40.0 days for hydrocephalus, 21.3 days for chronic subdural hematoma, 21.5 days for UGI bleeding, 32.7 days for seizure, and 12.6 days for SIADH.

6) There was no significant difference between Glasgow Coma Scale and incidence of complications, such as chronic subdural hematoma, UGI bleeding and SIADH, but there was significant difference between Glasgow Coma Sale and hydrocephalus, seizure and subdural hygroma(p<0.05).
