Cheekbone widened after deep plane facelift 3 years post-op (photos)

The widening of your cheek bone is likely from the "bunching" of the deep layers of tissues at the point where they are anchored into the bone. The only fix for this would be a surgical one where the tissues are carefully thinned. Given that this area is high risk for nerve damage as the frontal branch of the facial nerve passes along here, I would advise having the procedure performed by a skilled and experienced facelift surgeon. Steroid injections are unlikely to help.

I think the best option would be to start with a couple rounds of steroid injections to see if that offers improvement before undergoing a revision for that issue alone. The surgeon who performed the facelift should be able to perform those or another specialist. Ultimately, elevating skin and thinning that area surgically would also be an option and would be something I perform in office. Hope this helps answer your question.
