Abstract

Background: Fracture of Zygomaticomaxillary complex (ZMC) is considered to be one of the major facial fractures. it can lead to significant cosmetic and functional disorders. Three-dimensional (3-D) printing applications are gaining a remarkable attention in the field of craniomaxillofacial and plastic surgery. As the benefits of patient-specific 3-D printing become more established, surgeons are more likely to integrate this technology into their practice.
Aim of the study: This study evaluated the accuracy of the use of 3-D printed
reduction guide in the treatment of zygomatico maxillary complex fractures.

Patients & Methods: This study was conducted clinically on 12 adult patients with ZMC fractures indicated for open reduction and internal fixation. The patients were divided into 2 groups, (group A): the 3D printed reduction guide was used during the surgery and (group B): the surgical procedures were done without the reduction guide. The reduction and fixation time was recorded for comparison. Postoperative patient evaluation was performed with specific attention paid towards, accuracy of reduction, infra orbital nerve affection and postoperative ocular complications.

Results: There was a statistically significant difference in the surgical reduction and fixation time between the two groups. The error differences were more reduced for all landmarks in group (A) compared to group (B). The mean AI was decreased for all landmarks in group (A) compared to group (B).

Conclusion: The use of 3D printed reduction guide offers shorter operation time and improves the reduction of the fractured segments in comparison to the conventional reduction techniques.
