Purpose:

Isolated zygomatic arch fractures (IZAF) are habitually reduced at a distance, via a temporal approach. Open reductions are not recommended due to the associated morbidity and complications. However, performing closed reductions makes it difficult to determine whether it was done satisfactorily. This study aims to determine whether the acquisition of intraoperative images with a C-arm to evaluate IZAF reductions is a useful technique in treating such fractures.

Methods:

Our hypothesis is that acquiring intraoperative images with a C-arm reduces the need for a second surgery. Between 2009-2012, 50 patients who were diagnosed with IZAF requiring surgery were randomly distributed into 2 groups: 25 patients in the experimental group, where fracture reduction was performed and immediately corroborated intraoperatively for an adequate result using a C-arm; 25 patients were assigned to a control group where the fracture reduction was controlled with post-surgery imaging.

Results:

The results did not reveal significant differences between both groups (P = .05). Nevertheless, the experimental group had the advantage of being able to immediately reduce the fracture again if the result was unsatisfactory.

Conclusions:

Despite the fact that the results are not statistically significant, the authors recommend undertaking an intraoperative imaging analysis in areas where we are not certain of the reduction.
