Yes sure, but what would you recommend in my situation?
When the solution (L2 set back) to the asthetic problem (protrusive leftort area) can't be done because the doctors you've asked to do it say 'no', other suggestions are just MAYBEs and not substitutes for the solution.
Maybe a silicone implant or some deeply placed MACRO-lane. Both can be taken out or down if they don't do the trick. You would have to be cautious about going too far with the implant as I mentioned above and be aware that it is hard to reproduce the type of even over all favorable swelling you are wanting to reproduce. Those are just maybes for the CHIN as in maybe they will volumize the chin more in the way you liked it soon after the SWELLING.
The 'maybes' for the CHIN are limited to maybe they will given you the look of post op swelling to the chin area. But there is no 'maybe' about that compensating for the protrusive L2 area.
