How soon after spinal fusion and decompression can I get breast augmentation and a Brazilian butt lift?

Thank you for the question.  The best person to tell you that would be your spine surgeon and your plastic surgeon.  Get their opinions about the matter since it is important to be fully healed from one surgery before proceeding to another.  As for the prices, they differ from doctor to doctor and also depends on where you are located.  There is a tab on realself where you can check for estimated costs for surgeries.  Best of luck Dr. Michael Omidi.

I would suggest that you run your initial question by your spine surgeon.  If I were you, I would be very conservative not rush into plastic surgical procedures that may involve positioning changes in the operating room. When it comes to costs of surgery, there may be many “variables” involved. The specific surgeon's credentials/experience level (or lack thereof), the specific geographic area you are looking at, the different operations available, the location of the procedure (quality of surgery facility), type/quality of anesthesia provider… are some of the potential variables involved. You will find some average costs of surgery on this website and on individual plastic surgeons' websites as well.
In regards to outcome of the planned procedure, more important than costs of the procedures will be careful selection of your plastic surgeon. I would suggest starting with the American Society of Plastic Surgery and/or the Aesthetic Society of Plastic Surgery to obtain a list of well experienced board-certified plastic surgeons.
Then, I would suggest you visit a few surgeons whose practices concentrate on aesthetic surgery. Ask to SEE lots of examples of their work AND preferably speak/see patients who have had similar procedures done.
Be very careful with your decision-making. You will find, while doing your due diligence, that there are many different “specialties” who will offer their services to you; again, I strongly recommend you concentrate on surgeons certified by the American Board of Plastic Surgery. I would also suggest that you do not base your selection of plastic surgeon primarily on costs of surgery; keep in mind that revisionary surgery may be more costly in many ways. I hope this, and the attached link, helps. Best wishes.
