Aims and objectives
Show the contribution of the helicoidal tomography in the diagnosis and classification of facial trauma.
Methods and materials
297 patients diagnosed with facial injuries.
Each patient underwent a CT scan.
The scans were conducted with the use of spiral data acquisition technique in the transverse plane.
The following secondary image reconstructions were conducted for each patient with multiplanar reconstruction (MPR) and 3D volume rendering (VR).
Post-injury lesions of the facial skeleton were assessed and the presence of any loose displaced bone fragments was taken into consideration.
Post traumatic bone lesions were classified on the basis of the anatomical location of the fracture within :
branches and condylar process of the mandible.
Zygomatic arches and bones
Rate of patients with fractures in different anatomical locations :
Orbital wall fractures in 5,3% of cases
Frontal and maxillary sinus fractures in 8,3 %
Zygomatic fractures were found in 9,8% of cases
Mandibular fractures were identifed in 7,5%,
Isolated nasal fratures incuding the nasal bone...
CT is the standard of care for evaluation of suspected facial fracture because it is readily available,
and highly accurate in detecting even subtle fractures.
For the evaluation of fractures,
MPR and 3D sequences are widely used for successful identification of fracture sites.
the CT is also used to simultaneously evaluate for acute intracranial pathology which may be more urgent.

Is CT imaging of the facial skeleton in trauma inadequate? How can inadequacies be overcome?.
