CT-CBCT Imaging

The decision to perform CT/CBCT imaging depends on both the initial radiographic valuation and the clinical findings. If the plain radiographs are negative, with no signs of fracture, no fluid levels, no mucosal thickening of the sinuses, and no orbital or soft tissue emphysema and there is no indication of penetrating injury, then the chance of finding a significant midface fracture on CT/CBCT evaluation. There are very high incidence of intracranial damage in such patients, and there are important questions relating to the posterior wall of the frontal sinus, the nasofrontal duct, and the orbital roof, the answers can be find by CT/CBCT imaging technique.
Many central middle-third fractures require CT/CBCT estimation, although mild injury
After removing the metallic forging body , MRI can be used for adjunct characterization of soft-tissue sequelae and complications. As with CT scanning, MRI can demonstrate globe injuries, retrobulbar fluid collection (hematoma or other), subperiosteal hemorrhage, and hemorrhage along the optic nerve sheath, as well as the proximity of extraocular muscles to the fracture edges.[26] [27]
5.8 Ultrasound
Ultrasound has traditionally been used to image irregularities of soft tissue and is used extensively for examination of the abdomen and pelvis, and the soft tissues of the neck. Its role in maxillofacial surgery is less widely recognized. Gateno et al. investigated the use of ultrasound pre-operatively to aid in adjusting the mandibular condyle in relation to the glenoid fossa during osteotomy of the mandibular ramus. In maxillofacial trauma, ultrasound scanning has also been used to aid in the closed reduction of fractures of the zygomatic arch.
Regarding the usefulness of ultrasound in diagnosing facial fractures, Jenkins and Thaw reported that ultrasound had an accuracy of 86% and sensitivity of 85% in detecting orbital floor fractures. Our study showed that ultrasound can be used with 85% accuracy to diagnose fractures of the zygomatico orbital complex, but
