A bone fragment was compressing the left optic nerve within the nerve canal (yellow arrows). C, D. Axial and three-dimensional pre-operative CT showing a left zygomaticomaxillary complex fracture with medial displacement of bone fragments. E. During navigation-assisted endoscopic trans-nasal optic nerve decompression performed by an endoscopic rhinologist, a depressed bone fragment was identified in the distal part of the optic nerve canal. F. Bone fragment removal. G, H. Axial and coronal post-operative CT showing the removal and release of the bone fragments around the optic nerve canal (yellow arrows). I. Three-dimensional post-operative CT shows that the zygomatic fragment was repositioned symmetrically.
