Augmentation buttock-pexy using autologous tissue following massive weight loss

Area of Science:

• Plastic Surgery
• Body Contouring
• Bariatric Surgery Outcomes

Background:

• Massive weight loss, often following bariatric surgery, leads to significant changes in body aesthetics.
• Post-bariatric patients frequently experience buttock ptosis and loss of fullness, necessitating reconstructive procedures.

Purpose of the Study:

• To present a surgical technique for autologous tissue buttock augmentation during excisional body contouring in post-bariatric patients.
• To improve buttock shape, fullness, and overall aesthetic appearance in individuals who have undergone massive weight loss.

Main Methods:

• A medially based flap of subcutaneous tissue, with optional dermis, was transposed as a supramuscular autologous implant.
• This flap was integrated into a lower body lift or belt lipectomy, involving superior advancement and medial rotation of buttock tissues.
• The procedure aimed to tighten the buttocks, lateral thigh, and posterior thigh.

Main Results:

• The technique was successfully applied to 62 patients, demonstrating consistent and durable results up to 4 years post-operation.
• Common complications included wound dehiscence and persistent seromas, predominantly in the early stages of the series.
• A reduction in seroma rates was observed after the introduction of fibrin sealant, though further study is needed.

Conclusions:

• Combining abdominal body lift with autologous tissue buttock augmentation-pexy yields aesthetically pleasing and lasting buttock contour.
• This technique is presented as a dependable method for enhancing cosmetic results in post-bariatric body contouring surgery.
