Abstract

Objective: To assess the deviation of the fractured zygomatic bone involved in zygomaticomaxillary complex fractures after reduction using the proposed 3D-Printed Zygomatic Sliding Surgical Guide. Material and methods: Twenty arbitrary zygomaticomaxillary complex fractures were virtually simulated on ten digital skulls. Individualized twenty 3D-Printed Zygomatic Sliding Surgical Guides and infraorbital and zygomaticofrontal plates were designed following the created fractures. The segmented skulls, zygomatic bones, surgical guides, and bone plates were 3D printed. The zygomatic bone was reduced into the planned position using the Zygomatic Sliding Surgical Guide. The reduced zygomatic bones were fixed at two points guided by the surgical guide using the 3D-printed bone plates. The reduced skull was scanned, and reduction was assessed at the four zygomatic bone tails. Results: The zygomatic bones were reduced accurately into position with minimal mean deviations (0-0.6mm). Conclusion: The proposed 3D-Printed Zygomatic Sliding Surgical Guide is valuable for reducing fractured zygomatic bones into virtually planned positions.
