Soft semi-solid silicone buttock implants are considered permanent implants because they cannot rupture and leak silicone gel. Buttock/hip implants are a very good, safe, and long term reliable option for most patients seeking buttock/hip augmentation (at least in my practice). I prefer to insert the buttock implants through a 1 1/2 inch long incision along the inner curve of each upper buttock cheek at the level of the tailbone, similar to two opposing parentheses ")(" (concealed within the crevice between the buttock cheeks) and the hip implants through a ~ 1 inch incision just below the beltline above the hip region. The buttock implant should always be placed under or within (muscle thickness permitting) the gluteus maximus muscle. In this position, the implant is less palpable, less visible, and does not sag or shift/migrate over time unlike implants placed on top of the muscle or "subfascial". On the other hand, hip implants are placed under just the fascia because no significant muscle exists in this region. However, because they are much smaller and lighter, their likelihood of migration is relatively low. Because all of this, it is extremely important to seek consultation with a board certified plastic surgeon who specializes in this procedure so that the implant placement is precise for both locations. And in this case too, at least in my surgical practice, the infection rate is minimized to
