Abstract

Introduction: Reduction of zygomaticomaxillary (ZMC) fracture is often difficult to evaluate intraoperatively because of it peculiar anatomy and limited accessibility. The purpose of this study is to evaluate the efficacy of use of C-arm as a tool for intraoperative monitoring of ZMC fracture reduction.

Materials and methods: Group I (C-Arm) and Group II (control group) comprised of patients with isolated unilateral displaced Zygomatic complex (ZMC) fractures and having orbital volume change. The efficacy of use of C-arm intra-operatively was evaluated to analyse the reduction of fracture.

Results: It was observed that mean change in ocular volume was around 1.07cm2 for Group I and 1.51cm2 in Group II. Thus post-operative eye volume was near to normal in Group I than Group II. The change in ocular volume post-operatively was observed to be statistically significant (p-value < 0.05) in both the groups. Post HOC Tukey statistical analysis determined the intergroup relation in change in eye volume between normal, pre- and post-operative and was found to be statistically significant (p-value < 0.05). The intergroup comparison between Group I and Group II was done using ANOVA statistical analysis and was found to be statistically significant (p-value < 0.05).

Discussion: Our study revealed that C-arm is definitively an effective tool in the oral and maxillofacial surgery armamentarium, giving better results with minimal surgical exposure and by eliminating operator related error.
