What type of procedure would best remove my double chin? (Photo)

You most likely have significant fat deposits located both above and below the platysma muscle in your neck. Liposuction can only accomplish removal of the fat deposits above the muscle. A neck lift procedure accomplishes fat removal above the muscle with liposuction, and surgical extraction of the fat deposits below the muscle, which also includes a platysma plasty to significantly improve the jawline. Your BMI should be less than 32 before undergoing this type of procedure for best results

The reason you have and have had a double chin is that the body of your mandible is small esp in relation to your maxilla. The mentalis or chin region of the mandible projects nicely so you don’t need chin augmentation,
Still, on profile pictures your upper lip projects a lot more than your lower lip. You also most likely have a significant overbite dental occlusion. Individuals who have aesthetic beauty as they get older tend to have a more ideal bone structure that serves as a foundation to support the soft tissues.
Individuals like Carmen Dell'Orefice come to mind when we think of those who have fairly ideal aesthetics. What makes her jawline so great even in old age is not just avoiding sun damage. Her beauty comes from having been born with ideal facial bone structure. That large mandible protects her from developing a double chin, loss of jawline definition, jowls, and deep nasolabial folds.
Liposuction may give improvement but is not a treatment that addresses the primary problem which is bone structure.
Recognize when you attempt soft tissue solutions for skeletal problems the best patients should expect are partial improvement.
Delivering consistent quality liposuction results is also harder than most people most people realize.
The number of plastic surgeons that have mastered liposuction is pretty small. Most plastic surgeons think they are better at liposuction than they actually are. Finding the right provider for chin liposuction is not at all easy or straightforward.
To start the process I suggest patients schedule multiple in person consultation with local providers who seem to do a lot of liposuction.
During each consultation ask each provider to open up their portfolio and show you their entire collection of before and after pictures of previous patients who had similar facial characteristics.
An experienced surgeon should have no difficulty showing you the before and after pictures of at least 50 previous patients. This should be the case for whatever procedure you choose.
There are different options you can choose from. If you want a formal assessment from a facial skeletal perspective consider consulting with Oral surgeons in your area. For soft tissue treatment consult with plastic surgeons.
