Application of CT in maxillofacial trauma

1. Application of
Conventional
tomography
in Dentistry

2. Application of
Conventional Tomography
In Maxillofacial trauma

3. Role of imaging
Detection of Soft
tissue and bony
injuries
Characterization
Surgical
planning
CT preferred
 More accurate
 Easier to perform in multi-trauma, non cooperative patients
 Injuries other than simple nasal fracture

4. Mandibular fractures
Fractures of the angle, ramus,
condyle , coronoid ,
symphysis , or the body
Condylar fractures have been
detected in 64.8% of all
patients with mandibular
fractures using MDCT

5. • A 46-year-old male with mandibular fracture
resulting from falls. Axial image (a)
demonstrates a median fracture with soft tissue
edema. Axial image (b) demonstrates a median
fracture. Coronal image (c) demonstrates
condylar fractures with soft tissue edema .
Coronal image (d) demonstrates condylar
fractures. 3D images (e and f) to better
advantage show median and condylar fractures.

6. Midfacial fractures
including maxillary
fractures
Several types of midfacial fracture
• Le Fort I—lll
• Zygomaticomaxillary complex
• Anterior maxillary

7. • A 45-year-old male with midfacial
fractures resulting from falls. Axial image
(a) demonstrates maxillary and zygomatic
arch fractures with soft tissue edema .
Axial image (b) demonstrates maxillary
and zygomatic arch fractures. 3D images
(c and d) to better advantage show
zygomaticomaxillary complex fractures.

8. Temporal bone fractures associated with mandibular trauma
Axial noncontrast CT scan with bone
windows reveals a longitudinal
temporal bone fracture
Axial noncontrast CT scan with
bone windows reveals a transverse
temporal bone fracture
Axial noncontrast CT scan with bone
windows demonstrates a complex
fracture with a transverse component
and an oblique component

9. Orbital fracture
Orbital Floor
Medial Orbital Wall
Orbital Roof
Lateral Orbital Wall

10. Coronal CT image shows fracture
