The Signficance of Intraoperative Radiograph in Treatment of Zygoma Fracture

Park, Sung Hoon; Park, Yong Joon

Abstract

PURPOSE: The surgical treatment of zygoma fracture use generally three point fixation of the zygomaticofrontal suture, inferior orbital rim and zygomaticomaxillary buttress. But, this procedure has the disadvantage that we cannot know symmetry of the zygoma and visualize the reduction of the zygomatic arch. So, we take a intraoperative simple radiograph(zygomatic arch view) in reduction of zygoma fracture.
METHODS
From 2004 to 2006, We compared 21 patients with taking a intraoperative simple radiograph and 28 patients with not taking a radiograph. To assess the difference between the two groups, the authors compared the patients' subjective symptoms and measured the axial angle of the zygoma and zygomatic arch and the degree of the zygomatic arch inclination on zygomatic arch view. And we compared intraoperative simple radiograph with postoperative facial bone CT scan.
RESULTS
There was significant difference in appearance of subjective symptoms and the degree of zygomatic arch inclination representing the local contour of fractured zygomatic arch. And intraoperative simple radiograph is accorded with the postoperative facial bone CT scan.
CONCLUSION
We think that taking a intraoperative simple radiograph in the treatment of zygoma fracture is satis-factory methods in cosmetics and accuracy of reduction.
