ABSTRACT

Cryolipolysis is a nonsurgical technique for localized fat reduction. With the increased risk of complications from more invasive methods such as liposuction, cryolipolysis presents a promising method for nonsurgical body contouring. This study presents a systematic review of the available clinical data, with an emphasis on the efficacy, methods, safety, and complications of cryolipolysis. To identify clinical studies that assessed outcomes of cryolipolysis, a systematic review of the MEDLINE and Cochrane databases was performed with the search algorithm cryolipolysis OR cool sculpting OR fat freezing OR lipocryolysis. The primary literature search returned 319 articles. After inclusion criteria were applied and additional articles were idenfied via manual review of article references, 19 studies were selected for review. Average reduction in caliper measurement ranged from 14.67 percent to 28.5 percent. Average reduction by ultrasound ranged from 10.3 percent to 25.5 percent. No significant impact on lipid levels or liver function tests after cryolipolysis treatments was noted in any study. Only mild, short-term side effects, such as erythema, swelling, and pain, were noted. Paradoxical adipose hyperplasia was described in one patient. Cryolipolysis is a promising procedure for nonsurgical fat reduction and body contouring and presents a compelling alternative to liposuction and other, more invasive methods. This procedure appears to be safe in the short term, with a limited side effect profile, and results in significant fat reduction when used for localized adiposities. It remains unclear whether posttreatment manual massage and multiple treatments in the same anatomic area enhance the efficacy of cryolipolysis.

CONCLUSION

This study presents the first systematic review of the available data on cryolipolysis. Although the body of evidence is limited because of the nascence of this procedure, cryolipolysis is a promising procedure for nonsurgical fat reduction and body contouring. While the outcomes of cryolipolysis are rather modest, this technology is well suited for patients who desire nonsurgical spot reduction at modestly sized adiposities. Cryolipolysis appeals to both men and women and is an effective means by which new patients can be drawn to the aesthetic surgery practice. Although the specific mechanism of cryolipolysis has not been completely elucidated, this procedure appears to be effective and safe in the short term, with a limited side effect profile. Posttreatment manual massage has the potential to improve the efficacy of cryolipolysis. Multiple treatments in the same anatomic area may lead to further fat reduction, although the efficacy of cryolipolysis appears to be attenuated with successive treatments. The efficacy of this technique in areas that have been treated previously with liposuction remains to be studied. Future studies should address which treatment sites are most amenable to cryolipolysis to enhance treatment stratification for body contouring patients and should evaluate a potential role for cryolipolysis in skin tightening and the treatment of cellulite.
