Mommaerts old paper. I can't be bothered to find it but there is an older thread on here which details why he is a questionable choice at best. With that said the ZSO has value -if you lack forward and lateral projection. I've seen the user Stupidjaws results and they were exellent, just as good as the pictures from your link.
If you do not lack forward or lateral projection however you will be underhelmed or even displeased with the results. It is not much bone that is mobilized and the cheekbone will not be "raised". The improvement in the under-eye area is due to soft tissue being supported from below, if you already have support in this area it will not do much at all. Also beware of nasolabials which might appear if you advance your cheeks further than the rest of your midface.
For higher cheekbones, which is a masculine trait, as well as a more prominent ridge I am interested in deep long-term fillers. Implants in this area I object to empirically as I've yet to see even one good result for men.
I am pretty confident i could get the exact same results as the guy in that paper.
The only thing i could find about mommaerts on here that is worrisome is a surgical horror story. Well, i hate to break it to people, but this is a risk with every single surgeon in the world. They all have horror story patients, probably a mix of poor bastards who genuinely got f**ked over by statistical anomaly, BDD nutjobs and malicious shills (anyone who has investigated eppley and yaremchuk for example, knows of the huge amount of shills both have attacking eachother)
that said, Zarrinbal is very well spoken of here, so if i were to get it i would probably get it with him since i want a chin wing anyway. Does anyone know if a ZSO and chin wing can be performed in the same operation? I can't see why not.
