Buttock implants are usually done under general anesthesia. I have made excellent experience with asking my team of anesthesists to add an epidural which can keep you pain free in the first 24 hours when pain can sometimes be intense. That is surgeon preference so not everybody will do that.
It is very difficult to determine the exact size and shape implant you will require to best match your ideal butt image without an examination by a board certified plastic surgeon. Not just any board certified plastic surgeon, but one with many years of frequently performing breast augmentation...
Thank you for your question. Every surgeon has their own post-operative protocols. I recommend asking your surgeon how he/she would recommend you care for your incisions. Best of Luck,
