The aim of this study was to compare ultrasonography with CT scan and submentovertex films in the visualization of zygomatic arch fractures.
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.
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).
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.
本研究旨在比较超声、CT 扫描和颏顶位片在显示颧骨弓骨折中的作用。
对 17 例（男 10 例，女 7 例）疑似颧骨弓骨折的患者进行研究。将 CT 和普通 X 线片的数据与超声（使用 7.5MHz 探头的 Aloka 3500（日本东京）超声设备）的结果进行比较。探头沿骨折的颧骨横向放置以评估其全长。所有的超声图像均由同一名超声医生进行采集和解读，其并不了解 CT 和普通 X 线片的结果。
超声在评估骨折的颧骨弓方面是准确的，其敏感性为 88.2%（17 例患者中有 15 例，2 例为假阴性），特异性为 100%（无假阳性）。
超声在显示颧骨弓骨折方面是准确的，可以作为普通 X 线片的辅助手段，以减少总的辐射暴露。
