Abdominoplasty Combined with Hip Expansion by Fat Grafting: An Evolution in Waistline Contouring

Abstract

Background: Recent sociocultural trends show numerous patients requesting more curvaceous profiles. Abdominoplasty techniques had evolved into a combination of fascial plication with liposuction of the lateral torso, but often left patients with “boxy” profiles. The senior author performs 360-degree liposuction of abdomen and back, hip expansion with structural fat grafting, excision of redundant soft tissue, and wide plication of abdominal fascia to create the desired profile. Methods: Retrospective review of patient charts and CosmetAssure claims of female patients treated from January 2014 through May 2022 identified 1125 patients with a minimum 6-month follow-up who underwent abdominoplasty using 360-degree liposuction of waist, back, and flanks; wide plication of the rectus abdominis muscle; and hip expansion with fat grafting. Authors reviewed pre- and postoperative photographs to evaluate the technique’s effectiveness. Results: Hip expansion with fat grafting combined with abdominoplasty was successfully achieved in 1125 cases. Average age was 38 years. Average body mass index was 29 kg per m2. Average amount of aspirated fat was 1896 mL. Average amount of fat injected into the bilateral hips was 493 mL. Complication rates were comparable to those observed in similar abdominoplasty series reported in the literature. Conclusions: Abdominoplasty combining liposuction of the waist, back, abdomen, and flanks followed by wide fascial plication and expansion of the hips with fat grafting is a safe, reproducible technique for female patients. This technique prioritizes the hip anatomical area as an aesthetic consideration in abdominoplasty and facilitates creating a harmonious hip-to-waist ratio characteristic of a feminine figure.
