Abstract

In panfacial fractures, reduction is difficult when the damage extends to the zygomatic suture, forming the outer facial frame, owing to loss of reference form on the other side. We report a case of panfacial fracture with zygomatico-maxillary complex treated using this navigation system.　A 46-year-old man was injured in a motorcycle accident, and panfacial fracture was diagnosed. His left zygoma was intact, but the right zygomatico-maxillary complex sustained a comminuted fracture and thus lost its anatomical form. In preoperative planning, the form of the left zygomatico-maxillary complex was mirrored to the right side.　We performed open reduction and internal fixation using a navigation system that captured the mirrored images. After general anesthesia, the reference marker was secured to the scalp using a head band. During surgery, the navigation system was used to fix the right zygomatico-maxillary complex. The navigation system was used to intraoperatively visualize the proper height, width, and anteroposterior projection of the face, which led to simultaneous confirmation of good facial reduction. The navigation system was very useful for surgery of the unilateral zygomatico-maxillary complex or comminuted fracture.
