Surgeons are known to be a highly narcissistic bunch. Surgery is like building a house. You get a lot of money while it's being built but afterwards you have a lot of incentive to move on to the next customer quickly. They simply don't care much what happens to patients after surgery completes. Often times, patients with bad outcomes won't even tell them. They lose faith and move on to another surgeon to fix it. Unless it's their area of interest, they won't be doing detailed surveys months and years out and research has little to no impact on their practice. There is inherent risk in surgery and it's difficult to measure, as new outcomes are always discovered.
In your case, I would think the risks are comparable to implants. About 60% of people are happy with them on realself. They don't seem to reverse well and that's part of the low satisfaction rating. I think for someone whose done it a few hundred times, the more serious risks (motor nerve damage, muscle damage, non-union, infection, etc) are low. Knowing your personality, the "less serious" risks like increasing or not fixing your asymmetry, worsening your gaunt look, or sensory changes, those are nominally low but not comfortably low considering what's at stake. To a surgeon, if your only complaint is that you look worse afterwards, that's not a disaster. A disaster to him is the patient next door who ended up in the ICU for the next 4mo.
