This question needs an expert opinion from a plastic surgeon or maxilo-facial surgeon.

I just had my jaw shaved for vanity reasons( wanted a more feminine jawline as I felted it looked too square). Like yourself I went online everywhere and found little information on this procedure in the US. I found a doctor ( Dr. Edward Miranda)in San Francisco that has a great deal of experience with this. I sit here now recovering as it's day number 13 for me. My doctor and I both agree I've been very lucky! It's been smooth healing and little to zero pain. Actually I stopped taking the pain killers two days later as they effected my body in a bad way( constipated etc). I have had breat implants and felt that was way more painful ( had small B went to D and was under the muscle). If you decide to go through with this - find the best doctor in your area. As of right now...it's been worth every penny for me.

Good luck!
