“…Since then ultrasonography has been used for diagnosis of different facial fractures with varying success. 3,5,10 The majority of authors believe that ultrasound is the most useful for visualization of zygomatic arch fractures. 3,8 …”

“…In both Forrest et al's 5 and McCann et al's 3 studies the correlation and accuracy of ultrasonographic findings were high (94% and .85%, respectively) but the sensitivity, specificity and the positive predictive values at the different sites were not distinguished from each other and there were no specific values for the arch fractures. Friedrich et al 8 found ultrasound in the visualization of zygomatic arch fractures highly reliable.…”

“…Although Forrest et al 5 had chosen CT for comparison, they did not distinguish the zygomatic arch from the other components of the ZMC. In this study the accuracy of ultrasound in the diagnosis of isolated zygomatic arch fractures using CT and SMV plain radiographs was compared because it is the most common and the first-step diagnostic modality.…”

“…4 The use of ultrasound in the diagnosis and management of facial trauma has been reported previously. 3,[5][6][7][8] McCann et al 3 used ultrasound with 85% accuracy in diagnosing fractures of the zygomatico-orbital complex (ZMC). According to Friedrich et al, 8 application of ultrasound is most useful for visualization of the zygomatic arch and the anterior wall of the frontal sinus.…”

Objectives: The aim of this study was to compare ultrasonography with CT scan and submentovertex films in the visualization of zygomatic arch fractures. Methods: 17 patients, 10 men and 7 women, with suspected fracture of the zygomatic arch were studied. The data from CT and plain films were compared with the ultrasonographic findings (Aloka 3500 (Tokyo, Japan) ultrasound equipment with a 7.5 MHz transducer). The probe was situated over the fractured arch transversely to evaluate its whole length. All of the sonograms were taken and interpreted by the same sonologist, who was not aware of the results of the CT and the plain films. Results: Ultrasound was accurate in assessing the fractured arches with sensitivity of 88.2% (15 of the 17 patients, with two false negatives) and specificity of 100% (no false positives). Conclusion: Ultrasound is accurate in the visualization of zygomatic arch fractures and can be used as an adjunct to plain films to reduce the overall radiation exposure.

“…8,9 Image degradations by metal artefacts, such as those emitted by dental fillings, and the need for positioning of a traumatic patient inside imaging machines are other potential drawbacks of CT in orbital imaging. 10 Instead, some investigators have recommended orbital ultrasonography as an alternative to conventional CT. The available reports, however, are not uniform in terms of its accuracy, [11][12][13][14][15][16][17] probably because of imperfect methodologies and using outdated ultrasonography equipment in older series.…”

Objectives: To compare the diagnostic performance of ultrasonography and CBCT against CT in detecting orbital floor fractures. Methods: A total of 120 orbits with clinical suspicion of isolated orbital floor fractures underwent multislice CT scanning with coronal reconstruction; orbital ultrasonography using a standard machine equipped with a 7-to 10-MHz linear transducer; and CBCT. Patients with severe head and face injuries were not included. The diagnostic performance of ultrasonography and CBCT was reported assuming conventional CT as the imaging method of choice. Results: According to CT findings, fractures of the floor were present in 39 orbits. The sensitivity, specificity, positive-predictive value and negative-predictive value of ultrasonography in detecting orbital floor fractures were 87.2%, 100%, 100% and 94.2%, respectively. The corresponding values for CBCT were 97.4%, 97.5%, 95.0%, and 98.8%, respectively. Areas under the receiver operator characteristics curves of orbital floor fracture detection were 0.94 for ultrasonography and 0.98 for CBCT. Conclusions: When conventional CT cannot be performed in patients with clinically suspected orbital floor fracture and no severe or complex head and face injuries, CBCT could be used in detecting fractures as a reliable surrogate. Because of a lower sensitivity of ultrasonography, however, its use is limited in this regard.
