Lower face protrusion/swelling 8 months post Taylor Liberator, what's your advice? (Photos)

Hi, I had Taylor Liberator subscision around 8 months ago. After the initial swelling went down (about 4-weeks), I was left with lower face swelling. When I feel it, it is soft and slightly squishy. My Dr is insisting it will go away and is just soft tissue swelling/edema, and is treating with steroid injections but I have had about 4 lots of injections with no change to the face swelling. I was wondering if anyone else had thoughts on what it could be/treatment?
