Face fracture tips
Use sub mm cuts in orthogonal planes and 3D. Total dose for the whole face < 100 DLP, and
postoperatively can be as low as DLP 20-30.
If original cuts are malpositioned/ oblique reposition the acquired volume and reformat true axial ,
coronal and sagittal <mm cuts.
3D slices after cutting away C- spine and posterior part of the scull. Do 36 image rotations clockwise

Frontal sinus front and posterior wall
Lateral orbital wall
Margo supra and infraorbitalis
Zygomatic arch
Maxillary sinus walls
Orbital floor / muscle impingment
Optic canal
Orbital fissures especially superior fissure
Orbital hematomas
Nose piriform aperture
Mandibular joints
Dislocations
Foreign bodies
General tips:
Fracture incices:
Fluid( blood) in sinuses or subcutaneously
Air in wrong place – in soft tissue, orbits, intracranially
Zygomatic fractures:




Lateral orbit wall
Margo infraorbital
Zygomatic arch
Orbital floor- herniation? Compute volume of herniated fat.





Maxillary sinus
General dislocation- Dorsal? Rotation? Impingment of muscle in orbit or temporal?
Orbital floor/ blow out
Orbital floor- herniation? Compute volume of herniated fat.
Medial wall? Impingment?
Le Fort 1
Upper jaw loose.




Fractured maxillary sinus walls, all of them
Pterygoid processes fractured
Septum nasi fractured
Fluid levels in both max sinus
Check Pterygoids in coronal projection.
Make sure there is a straight sagittal view and a straight lateral 3D view,
LE FORT 2:
Maxilla loose
Fraktures in:





Lamina papyracea
Orbital floors
Fractured maxillary sinus walls, the lateral ones
Pterygoid processes fractured
Fluid levels in both max sinus
Check Pterygoids in coronal projection.
Make sure there is a straight sagittal view and a straight lateral 3D view,
LE FORT 3:
Craniofacial dysjunction,
Fraktur in:




Lamina papyracea
Nasal bone/ suture
Lateral orbitt
Arcus zygomaticus
Frontal sinus



Anterior wall impression?
Posterior wall? Intracranial air? Displacement in mm?
Recesses?? ( occlusion can lead to mucocele development)
Mandibula




Often 2 or more injuries, always check contralateral side.
Teeth numbered by quadrant 1-4 and number 1-8. Tooth faces mesial, distal, lingual ,
buccal.
If injured joint check auditory canal
Mention ramus overlap, caput dislocation, size of fragments.
Scull base fractures:




Intracranial air
Blood in sphenoid sinus
Fluid in mastoids or inner ear.
Check carotid canal and optic canal!
Temporal bone fractures


Lengthwise most common. Check ossicles, geniculate ganglion
Crosswise more seldom. Check inner ear !
CAVE:
Eye muscle entrapment, orbital haematoma, optic canal carotid canal.
Associated injuries
C-spine, especially in the elderly
