title: Power-assisted gluteal augmentation: a new technique for sculpting, harvesting, and transferring fat.
abstract: BACKGROUND
  A simple and reproducible surgical technique for gluteal shaping and augmentation with autologous fat is needed.
  
  
  OBJECTIVE
  The authors describe a novel approach to large-volume gluteal augmentation that combines power-assisted liposculpting and fat harvesting of the zones around the buttock with autologous fat transfer.
  
  
  METHODS
  One hundred ten patients who underwent gluteal augmentation were evaluated in a prospective study. Liposculpting and fat harvesting were performed with power-assisted liposuction. Fat then was transferred to the gluteal region with simultaneous power-assisted vibration and tunnelization. A questionnaire to assess patient satisfaction was administered at 6 months postoperatively.
  
  
  RESULTS
  The mean body mass index of the patients was 30 kg/m(2) (range, 26-36 kg/m(2)). Liposuction volumes ranged from 1400 to 5000 mL, and injection volumes ranged from 300 to 900 mL per side for each session. Operating times ranged from 60 to 120 minutes. Patients were monitored for an average of 20 months (range 12-48 months). Complications included a burning sensation in 5 of 110 patients (4.5%), persistent swelling in the lower back in 3 patients (2.7%), and a mild infection in 1 patient (0.9%).
  
  
  CONCLUSIONS
  Power-assisted gluteal augmentation with autologous fat is an efficient, safe, and reproducible procedure that produces an aesthetically pleasing gluteal projection and contour.
