Do buttock tissue expanders exist?

Thank you for your question whether buttock tissue expanders exist. Tissue expanders come in a variety of shapes and sizes. Tissues expanders are not targeted for specific  body parts. However, if you are looking for buttock tissue expanders,  there are certainty large tissue expanders that can be placed in the buttock. Typically, this would be a round tissue expander that I would use for breast reconstruction. In the US, the largest FDA approved silicone buttock implant is 712 cc. That is an off the shelf buttock implant. However, custom buttock implants can be created. If you want to achieve 1500 cc in each buttock, I would suggest a staged approach. Indeed, buttock tissue expanders may be the safest way to achieve this. I would be concerned in the expansion of the buttock tissue to achieve maximum results. It may take several months to get the buttock skin expanded, but I believe conceptually, this buttock expansion is possible. Once the buttock tissue has been expanded with the buttock expander, a custom implant will have to be created. However, there are blocks of semi-solid silicone which could be carved to your desired buttock shape and size. Please seek an experienced board certified plastic surgeon.  Thank you for your question about permanent buttock augmentation with FDA approved, semi-solid silicone buttock implants.  I hope that I have answered your questions regarding whether buttock tissue expanders exist.  I specialize in buttock implant insertion.  If you have any more questions regarding buttock implants, buttock implant surgery, buttock implant insertion, or buttock implant revision, please contact my office. Since buttock implant surgery is a big procedure, please seek an experienced, board certified plastic surgeon with significant experience buttock implant insertion.   Do your research.   If you cannot find an experienced, buttock implant plastic surgeon in your neighborhood, consider traveling out of state if you must. Sincerely, Dr. Katzen. (“Verified” Plastic Surgeon, certified by the American Board of Plastic Surgery, Fellow of the International Society of Aesthetic Plastic Surgery, American College of Surgery, and International College of Surgery and member of the American Society of Plastic Surgery, American Academy of Cosmetic Surgery and RealSelf Hall of Fame.)

you will need to start off with a smaller size implant and slowly increase the size after the pocket has stretched. It would need to be a custom implant. Please remember to choose a Board Certified Plastic Surgeon who specializes in this procedure and is well known for it. 

 On one hand, there is no limit to the size of buttock implant that can be custom made. On the other hand ,however, there is indeed a limit for each individual patient’s anatomy.  Regardless, every patient must first start out with an implant that physically fits within their buttock muscles (i.e. “intramuscular” pocket).   It is never a good idea to put the implants on top of the muscle or “subfascial” -  these positions will almost always lead to implant visibility and a very unnatural look. . From there they can undergo several more operations at six or more months intervals to upsize until they achieve their desired final size. Hope this helps.
