The purpose of this study was to evaluate the usefulness of C-arm fluoroscan with a balloon catheter in patients undergoing closed reduction of zygomatic arch fractures.All patients who had zygomatic arch reduction surgery between 2006 and 2015 were identified and classified into 2 groups. Group A included those patients who underwent closed reduction of zygomatic arch fractures. Group B included those who underwent zygomatic arch reduction surgery with a C-arm fluoroscan and supporting balloon. A balloon catheter was used to stabilize the zygomatic bone after reduction. Results were scored from 1 (poor) to 3 (good) to assess surgical outcomes based on 3 criteria: alignment of the zygomatic arch on a postoperative computed tomography scan, facial asymmetry in photography, and the patient's subjective satisfaction.The authors enrolled 32 patients with zygomatic arch fractures. 18 patients underwent closed reduction for zygomatic arch fractures (group A), while 14 patients underwent closed reduction with C-arm fluoroscan and balloon support (group B). The average score for group A was 2.00 for alignment, 2.56 for facial asymmetry, and 2.67 for subjective satisfaction compared with 2.64 for alignment, 2.86 for facial asymmetry, and 2.79 for subjective satisfaction in group B. There were statistically significant differences in the alignment and facial asymmetry scores between the 2 groups.The authors suggest that C-arm fluoroscan with balloon support is a useful modality for reduction of zygomatic arch fractures that provides better surgical outcomes than conventional closed reduction surgery.
