Hey there....I have the same thing going on with my face...the narrowness, sunken cheeks...high cheekbones protruding outward....I was told that once the expansion phase of my tmj treatment was over, I would see a dramatic change in the facial appearance. This can be achieved with Functional Jaw Appliances.....NOT surgery. IMO, that is way too invasive. Usually the tmj specialist that are neuromuscular...and Functional Jaw Orthodontists understand this concept. My daughter is going through this phase as we speak as well.....and getting remarkable results.
