In the past 25 years, several different techniques of lipoinjection have been developed. The authors performed a prospective study to evaluate the patient satisfaction and the rate of complications after an autologous gluteal lipograft among 351 patients during January 2002 and January 2008. All the patients included in the study requested gluteal augmentation and were candidates for the procedure. Overall satisfaction with body appearance after gluteal fat augmentation was rated on a scale of 1 (poor), 2 (fair), 3 (good), 4 (very good), and 5 (excellent). The evaluation was made at follow-up times of 12 and 24 months. The total amount of clean adipose tissue transplanted to the buttocks varied from 100 to 900 ml. In nine cases, liponecrosis was treated by aspiration with a large-bore needle connected to a 20-ml syringe, performed as an outpatient procedure. Infection of the grafted area also occurred for four patients and was treated by incision drainage and use of antibiotics. Of the 21 patients who expressed the desire of further gluteal augmentation, 16 had one more session of gluteal fat grafting. The remaining five patients did not have enough donor area and instead received gluteal silicone implants. At 12 months, 70% reported that their appearance after gluteal fat augmentation was "very good" to "excellent," and 23% responded that their appearance was "good." Only 7% of the patients thought their appearance was less than good. At 24 months, 66% reported that their appearance after gluteal fat augmentation was "very good" (36%) to "excellent" (30%), and 27% responded that their appearance was "good." However, 7% of the patients continued to think that their appearance was less than good. At this writing, the average follow-up time for this group of patients has been 4.9 years. The key to successful gluteal fat grafting is familiarity with the technique, knowledge of the gluteal topography, and understanding of the patient's goals. With experience, the surgeon can predict the amount of volume needing to be grafted to produce the desired result. Although the aim of every surgeon is to produce the desired augmentation of the gluteal region by autologous fat grafting in one stage, the patient should be advised that a secondary procedure may be needed to accomplish the desired result.
