Would I be able to benefit from only getting liposuction 360 or is a tummy tuck needed? (Photos)

Thank you for your detailed question and corresponding photos. Based on your photos, I think you would be a better candidate for a lateral tension abdominoplasty (tummy tuck) with liposuction of the back and flanks. Liposuction alone will not address the excess skin and would not have a significant result. Surgery will not address visceral fat and therefore you should lose weight with diet and exercise prior to surgery. With 15-20 lbs of weight loss, you would have a beautiful result with nice abdominal contouring. The recovery is two weeks and we manage your pain very well. I recommend seeing a board-certified plastic surgeon for an in person consultation to discuss your goals and a treatment plan that is right for you. At our practice we also provide consults via FaceTime or Skype for patients who live outside of NY. For more information, please visit our webpage.

Based on your pictures you will not be happy with just the liposuction, I would recommend a tummy tuck with lipo bbl at the same time. These procedures can be done a t the same time as long as you are healthy. Best of luck!

Concerns about the appearance of the abdomen are very common among patients consulting with a plastic surgeon. Just like every patient is different…so too is every abdomen. Different problems require different solutions. Your board certified plastic surgeon is uniquely trained to identify the problems as well as the appropriate solution.
The abdomen is commonly addressed via liposuction or abdominoplasty (“tummy – tuck”). Which procedure is best is dependent upon the source of the problem. 
Excess fat deposits underneath the skin can be addressed via liposuction. Liposuction will not address any other issues and may worsen the situation if there are other factors at play (such as skin excess and muscle laxity, see below)
Commonly patients concerns are centered around issues of excess skin as well as fat. A third factor, which is often overlooked by most patients is abdominal wall muscle laxity (typically seen in post partum mommies).  The tummy tuck, also known as abdominoplasty is a surgical procedure designed to eliminate excess skin and fat and tighten the muscles in the abdominal wall to create a smoother and slimmer contour. The tummy tuck is designed to target areas of the abdomen that have not responded to diet and exercise, making it particularly popular among people that have a lot of loose or sagging skin around the abdominal area due to significant weight loss, as well as women with excess skin and stretched abdominal muscles following pregnancy and childbirth. 
Candidates for tummy tuck should be already at or near their ideal weight for optimal results. It is recommended to women that are planning on becoming pregnant to postpone the procedure until they are finished having children.
Ultimately, the answer to your question is dependent upon what the underlying problem is (fat, skin, muscle). If you are truly in need of an abdominoplasty, you are likely to be disappointed with the results of liposuction alone (as liposuction is likely to worsen the appearance of laxity).Based upon your photos, you would benefit from a staged abdominoplasty with waistline contouring liposuction. These cannot be performed simultaneously as aggressive thinning of the abdominal flap during tummy tuck can lead to healing difficulties.
As always, discuss your concerns with a board certified plastic surgeon (ABPS)
