How to get a bigger butt and hips when petite? HELP!!

Dear Remera, Thank you for your pictures.  In my opinion, I would recommend  buttocks augmentation with implants.  I do not think you can get the outcome like Kylie Jenner but you can certainly get remarkable improvement.

     This will provide you the most stable result in the long run. For over 10 years I had practice buttocks augmentation using fat grafts. Although you can achieve good volume of the buttocks with fat grafting IT IS EXTREMELY DIFFICULT TO ACHIEVE ADEQUATE LONG-TERM PROJECTION WITH FAT GRAFTING ALONE. The goal of all women is to increase buttocks projection. The fat is simply too soft to push the firmer tissues of the buttocks skin out to get the desired projection. The best and most consistent way to get projection is to the use buttocks implants.

    The buttocks implants are made of soft solid medical grade silicone. These implants come in various shapes (oval, round), sizes and projections. They are not like the first generation of buttocks implants which were very firm. These soft solid implants that closely mimic and feel like buttocks tissue. Buttocks implants are different than silicone breast implants. Silicone breast implants are made from medical grade silicone which is extremely soft. Silicone breast implants have a small potential for rupture.  The buttocks implants do not rupture or deflate.

    The procedure is performed as an outpatient procedure. General anesthetic is required. The procedure typically consists of enhancing the buttocks through incisions that are made on either side of the upper buttocks crease. This is a very well hidden incision. This allows for the implant to be placed typically underneath the fascia (covering) of the muscle but the implant may be placed within the substance of the muscle if the patient is extremely thin. Additionally, the liposuction may be beneficial to contour the abdomen and waistline.  This will further enhance the body contour.  If necessary the fat obtained from the liposuction can be used to modestly enhance volume.   Incisions for liposuction are very small typically only requiring one or two stitches for closure. Prior to closure of the incisions for the buttocks implants, drainage tubes are required to reduce the possibility of fluid (seroma) accumulation around the implants. The buttocks implants incision are closed with dissolvable stitches. A compression garment is extremely helpful after surgery to minimize swelling, to reduce the possibility of fluid (seroma) collection. After surgery,  one day of bed rest is required. After day one, the patient is strongly encouraged to get up and walk frequently. Typically the first office visit after surgery is within's 48 to 72 hours.

     Remember if you're considering buttocks augmentation with implants it is always wise to consult with a board certified plastic surgeon that has experience with buttocks enhancement.  Best wishes.
