Background Adipose tissue cooling, under controlled conditions, induces physical effects on subcutaneous tissue called cryolipolysis (CLL), which has been proposed as a method to reduce noninvasively the amount of adipose tissue. Although CLL has been widely utilized in clinical practice and many favorable results have been reported in clinical studies, very few published studies have dealt with the effects of such therapies on human adipose tissue. Objectives The aim of this study was to evaluate, through histopathological examination, the in vivo effects of CLL on human adipose tissue. Methods Six patients to be submitted to abdominoplasty were enrolled in the study. Samples were taken from the surgical patch, respectively, 15 days (2 pts), 45 days (2 pts), and 60 days (2 pts) after a single standard session of CLL. Control samples were derived from the nontreated areas of the surgical patch. Results Disruption of the adipocytic membranes was evident in all treated areas, with a reduction of cell dissolution in the 60-day samples. Focal dissolution and homogenization of the collagen fibers was evident, resulting in the dissolution of the interlobular fibrous septa. A mild inflammatory response was observed in the 15- and 45-day samples. Neocapillarizzation was observed in the 45- and 60-day samples. Conclusions The lesions demonstrated in adipocytes confirm the theoretical premises of a usefulness of CLL in the treatment of localized adiposis. The alterations in the connective stroma could lead to a structural reorganization and consequently to the in vivo external appearance of the treated areas.
