i'll take a shot at it (no pun intended) even though it's difficult to say without
1. seeing (frontal, profile, birds eye) pictures of the patient
2. without scrolling through coronal, axial, and saggital CTs
I'd imagine this pt has L enophthalmos which makes this a functional and cosmetic repair (if he didnt lose his eye with the GSW which it doesn't look like he would have)
Your deformities include discontinuous zygoma, depressed orbitozygomatic (OZ) complex, downward and inward rotation of the orbitozygomatic complex. I don't see much of an issue with the NOE region as you have alluded to.
Goals of treatment: Restore orbital volume and facial symmetry
My treatment would include: Perform model surgery on the orbitozygomatic complex with fronto-zygomatic, sphenozygomatic, and zygomaticomaxillary osteotomies (the zygomaticotemporal area already discontinuous) Place the OZ complex in the desired position and make a custom implant that will span the discontinuity (or you couldtake the easier route of planning on just plating/meshing across that discontinuity). Intraoperatively, use a hemicoronal and intraoral approach, mobilize the OZ complex with osteotomies, rotate upward and outward, fixate, apply the custom implant to span the defect, explore the floor and place filler (such as calvarium since you have a hemicoronal already) to additionally help restore volume of not already done with just rotating the OZ complex.
why did you not include the entire maxilla in your model (zygomaticomaxillary buttress)? My treatment is by no means the only way to treat this case. there are less invasive ways to providing purely functional treatment that are less involved. Your zygoma projection really isn't all that bad. It's mostly an issue of orbital volume. But what do i know. I'm just a dentist.
I bet the stereolithography business is loving the war there.
