Assessment of the adequacy of closed reduction in fractures of the zygomatic arch using "C"-arm image intensifier.

Major problems in closed reduction of isolated, minimally displaced, and depressed zygomatic arch fractures are blind nature of the technique, reliability on digital palpation, reduction click, and step deformity between fragments. The purpose of this study was to objectively confirm the adequacy of closed reduction intraoperatively and the usefulness of the "C"-arm image intensifier. A total of 12 patients with 1- to 8-day-old unilateral isolated and depressed zygomatic arch fracture underwent closed reduction under "C"-arm image intensifier.
