Allow me to share with you some information that you maynot hear elsewhere. There are only two proven safe and relatively effectivemethods for Buttock Augmentation: 1) Autologous FatTransfer (using your own fat, transferring from one area of the body to theother) and 2) Buttock Implants (semi-solid silicone rubber implants thatcannot rupture &/or leak). Both are very good options so what it comes downto, like any surgery, is proper patient selection. Indeed because at least 50+% of the fat transferred will melt away within a year, most patients are notgood candidates because they lack an adequate amount of fat to harvest. Anothertip is that if you gain weight for the procedure, the fat that you lose firstwhen you go back down to your baseline weight after surgery is in fact that fatthat you originally gained and transferred into your buttocks...so don't fallvictim to this recommendation.Although using your own fat is relatively safe, the one serious complication that canrarely (< 1%) happen is "fat embolism" in which some of the fatgets into the blood stream and travels up into the lungs, heart, and/or braincausing serious problems. This complication is more likely to happen with thelarger amount of fat being transferred. This can also happen when using fillers like PMMA and hyaluronic acids. Also fillers, when injected in large quantities, have a relatively high tendency to migrate away from the original area they were placed and tend to stimulate alot of inflammation and subsequent scar tissue/hardening. And finally, the risk of serious infection when injecting large volume fillers is unacceptably high and dangerous. Thus buttock/hip implants become a very good, safe, andlong term reliable option for most patients seeking buttock augmentation (atleast in my practice). I prefer to insert the buttock implants through a single2 ½ inch long incision over the tailbone (concealed within the crevice betweenthe buttock cheeks) and the hip implants through a ~ 1 inch incision just belowthe beltline above the hip region. The buttock implant should always be placedunder or within the gluteus maximus muscle. In this position, the implant isless palpable, less visible, and does not sag or shift/migrate over time unlikeimplants placed on top of the muscle. Therefore it is extremely important toseek consultation with a board certified plastic surgeon who specializes inthis procedure. And in this case too, at least in my surgical practice, theinfection rate is minimized to ~5%. Glad to help… @drryanstanton
