From the SAFE to the SAFEST Liposuction: Combining PAL and RFAL Technology in Body Contouring Procedures.

[BACKGROUND] The SAFE liposuction technique is a worldwide extended method used to achieve great and reproducible results after the surgical aspiration of fat. We propose an evolution of the technique to address one of the major limitations of liposuction, loose skin. The SAFEST liposuction technique combines PAL and RFAL to achieve skin tightening and fat reduction with minimal added morbidity.

[METHODS] Patients treated with the SAFEST liposuction technique between December 2019 and February 2022 were included in the study. Demographic and surgical data were collected retrospectively. Photographs and satisfaction interviews were conducted preoperatively and 12 months postoperatively in every case.

[RESULTS] Sixty-five patients (58 female and 7 male) were included in the cohort, and a total of 169 anatomical areas were treated with the SAFEST liposuction technique (abdomen, arms, back, flanks and thighs). Globally, satisfaction at 12 months follow-up was of 94.1% and complications only presented in 4.7% of the treated areas. 6 of the 38 treated abdomens (18.4%) presented a complication (4 seromas and 2 access point infections) and 2 of the 38 treated flanks (5.3%) presented one (2 seromas). The rest of the treated anatomical areas (arms, back and thighs) showed no complications and high satisfaction rates.

[CONCLUSIONS] The SAFEST liposuction technique achieves outstanding and satisfying results with minimal complications by safely combining the advantages of two different technologies, PAL and RFAL. The main advantages of the presented technique are the skin tightening, the body ligament contraction, the coagulation and the reduction of the operative time.
