Literally one hour ago, I treated a person with precisely the same issues you appear to have with immediate, extremely gratifying results. It is quite possible that the prior fat pad removal, by diminishing the supportive and contouring volume of the cheek indirectly led to the more prominent jowls along the jawline you dislike now. Frankly, when creating a treatment plan for jawline jowls, we routinely consider nonsurgical cheek augmentation with volumizing fillers to help lift and shape the cheeks to create a more heart-shaped face and to secondarily diminish smile folds, and jawline jowls. So, a skilled augmentation of the cheeks would be a first thought. Next, the jawline jowls may be more directly addressed by augmenting the area in front of the ears (preauricular region), as well as directly defining the jawline itself with a volumizing filler. Finally, a nonsurgical filler chin augmentation would further help to straighten and define the jawline . No need for expensive bells and whistles devices that to date have far more machine manufacturer supported marketing hype to back them than hard science. Make sure that you consult with a board certified aesthetic physician and insist upon seeing his/her personal before and after photos before agreeing to proceed. Best of luck.
