[The value of ultrasonography in the diagnosis of zygomatic arch fractures].

In 15 cases ultrasonograms were used to verify the result of a zygomatic fracture reduction and were correlated to conventional x-ray films. Both the pre- and postoperative ultrasonograms demonstrated all fractures of the zygomatic arch. Ultrasonographic imaging of the non-exposed bone surfaces enables the operator to monitor the reduction of zygomatic arch fractures intraoperatively, and thus optimize the treatment results.
