INCIDENCE OF SKULL FRACTURE IN PATIENTS WITH HEAD INJURY ON CT SCAN

Skull Fracture in Patients with Head Injury on CT Scan

Abstract

Skull fracture takes place when there is a discontinuity in the bone, this break signifies that a fracture has taken place. Skull fracture takes place most commonly caused by a trauma to the head which is significant enough to break at least a single bone.

OBJECTIVE: To determine the incidence of skull fracture in patients with head injury on CTScan.
METHODS: The study was conducted on 150 patients with head injury, Any trauma type, fracture type and fracture site were assessed through CT Scan. Scanogram of 250mm was taken. The table/gantry then advances a specific distance from where 10 mm slices through the cerebrum and 5 mm slices through the base-of-skull
and posterior fossa. The axial plane described for CT brain was the orbitomeatal line. Coronal and sagittal
reconstructions were then usually at right angles to this. CT brain resulting in 3-plane soft and 3-plane
bone reconstructions being sent to PACS with a 3D reformat to allow reimport into the volume rendering
system for future use.
RESULTS: In current study majority of patients skull had no underlying fracture (83%). But most common skull
fracture was in frontal region (8.0%) after that in vault (6.3%) than in base of skull (2.0%) and in the last
zygomatic (0.7%). 

CONCLUSIONS: It is concluded that large number of patients who suffered head injury have no underlying skull fracture.
