Buttock lift – Buried thread suspension

It is also called purse-string suspension surgery. It improves buttock sagging due to inadequate support from loose skin in patients who present an abundant volume of the buttock. If such patients do not need to undergo buttock augmentation, they can consider this surgery to correct buttock ptosis.

This surgery is conducted by making a 0.5-cm incision at the central gluteal groove and both lateral sides of the buttock. Via such small incisions, Dr. Chuang embeds a buttock lift thread along the subcutaneous passage with a special tractor and pulls and hauls the suture to the center. Such an endocentric embedding suspension method tightens and lifts the droopy gluteal tissues superomedially to the center of the buttock (purse-string suturing). Finally, the thread is fixated deep in the periosteum at the incision of the center of the gluteal groove. The larger the number of buttock lift threads embedded, the tighter and more persistent the results would be. On an average, at least two threads should be embedded at each side of the buttock to attain distinct results. Such a surgery is merely aimed at buttock skin lift rather than filling or plumping up the buttocks, so the size of the buttock is not changed after the surgery. It is suitable for female patients with hypertrophic but droopy buttocks or early buttock sagging. Nevertheless, the strength and durability of using a buttock lift thread to support whole tissues vary along with individuals, and patients should avoid strenuous or continuous lower body activities after the operation in case of premature loosening of the buttock lift thread. Surgical results last for 2–3 years on average, and the surgery can be repeated in the future.

Surgical conditions


  • Type of anesthesia: IV sedation + local anesthesia
  • Type of incision: Three 0.5-cm incisions at the central gluteal groove and lateral side
  • Recovery: 3–5 days
  • Removal of stitches: 7–10 days

General instructions

No food and water on the day of surgery

  • Avoid lying in the supine position or sitting upright for 3 days postoperatively to prevent compression to the buttock.
  • Avoid running or jumping or other strenuous lower limb activities for 1 month postoperatively.
  • Avoid buttock or lower limb extension activities after the operation for the long term.
  • Wear buttock lift pants for 3 months postoperatively to stable the buttock shape.

Ideal candidates

  • Patients with mild buttock sagging who want to undergo preventive elevation
  • Those with plump buttocks but mild laxity or droopiness
  • Those who are unable to accept buttock prosthesis implantation or fat grafting
  • Those who would like a buttock lift within an extremely short time

Possible complications

  • Buttock asymmetry
  • Premature loosening of the buttock lift thread
  • Exposure of the suture node
  • Excess tightening of the buttock (temporary)
  • Results short of expectation

Surgical advantages

  1. The effects of buttock lift are immediately noticed.

  2. The surgery is simple and very safe.

  3. The surgical incision is small, and the recovery is rapid.

  4. There is no risk or complications of prosthesis implantation or fat grafting.

Surgical drawbacks

  1. Postoperative pain is relatively obvious.

  2. Surgical results may last for a short time.

  3. Lower body activity is limited after the operation.

  4. The buttock lift thread may become prematurely loose due to strenuous activities.

  5. It is not applicable for patients who love exercises or fitness.
