Gluteal/Body Augmentation

Many body parts present skin depression or asymmetry due to congenital defects, prior trauma or surgeries. Since most deep and large-area body depressions are difficult to be corrected by nonsurgical methods such as the injection of hyaluronic acid and results last for a very short time, autologous fats convenient for collecting and grafting become the most economic option for filling large-area body depressions. Similar to autologous fat breast augmentation, this surgery needs to first purify and filtrate adipocytes collected by liposuction from abdomen or thighs, and then mix them with growth factors before injecting them into the sunken site at a proper volume. Nevertheless, because the self-absorption rate greatly varies along with the activity patterns of different parts, secondary fat grafting may be needed to achieve satisfactory results.

Apart from addressing body surface defects, autologous fats are used to improve or enhance the body curvature or for other simple esthetic purposes, such as buttock augmentation, pectoral reshaping, muscular texture modification (such as hand desquamation or knee or calf curvature), sculpting six packs in combination with ultrasonic high-definition muscular etching or even revision of skin sinking due to a prior improper liposuction. Because its clinical applications are quite extensive and flexible, patients need to thoroughly discuss with Dr. Chuang in making their surgical plans.

Surgical conditions


  • Type of anesthesia: IV sedation or general anesthesia
  • Type of incision: A 2-mm needle hole at the sunken sites

    Incisions for liposuction (approximately 5 mm)

  • Recovery: 2–3 days
  • Removal of stitches: 7 days

General instructions

No food and water on the day of surgery

  • Avoid compression to the fat injection sites for 1 week postoperatively.
  • Avoid excess cold or hot stimulus to the fat grafting sites for 2 weeks postoperatively.
  • Avoid vigorous exercises or stretches of the affected sites for 1 month postoperatively.
  • Avoid wearing too tight clothes for 3 months postoperatively to prevent the inhibition of fat growth.
  • Avoid a drastic loss of body weight for 6 months postoperatively to a year and have more high-gelatin and high-calorie foods to promote adipocyte survival.

Ideal candidates

  • Patients willing to undergo the enhancement and sculpting of muscular lines (such as buttock augmentation, pectorals, or abdominal muscles)
  • Those with appearance defects due to a congenital structural deformity
  • Those with muscular atrophy due to improper injections previously (frequently at the buttocks or thighs)
  • Those with muscular or skin defects or atrophy due to trauma
  • Those with a skin depression due to scar adhesion caused by prior surgery
  • Those with a skin depression or unevenness due to excess or improper liposuction

Possible complications

  • Subcutaneous lumps (temporary)
  • Skin unevenness
  • Fat calcification
  • Excessive absorption
  • Results short of expectation

Surgical advantages

  1. Abundant fats are available to fill large-area body depressions (large-volume augmentation).

  2. Fat collection is fast, convenient, and repeatable, and its application is economic and flexible.

  3. Fat grafting can be applied to any body part, so its application is extensive and flexible.

  4. Surgical results are long lasting and more stable than those obtained by nonsurgical methods such as the injection of hyaluronic acid.

Surgical drawbacks

  1. The fat survival rate and stability may vary along with the different characteristics of the affected sites.

  2. It may induce subcutaneous lumps or evenness (temporary).

  3. The filling of scar depressions could generally result in a high self-absorption rate.

  4. Effects at frequent motion sites (such as joints or buttocks) may not last for a long time.

  5. Severe and large-area depressions may be difficult to be simultaneously mended, and secondary fat grafting may be necessary in the future.
