Intercurrences And Complications Of The Use Of Cryolipolysis: Series Of Cases And Treatments.

The cryolipolysis technique uses selective and controlled cooling based on the principle that lipid-rich tissues are more susceptible to cold damage than surrounding water-rich tissues. Cryolipolysis stands out as a non-invasive method for body contouring without damaging subcutaneous tissue, becoming a popular treatment to noninvasively address localized fat accumulation and tone the dermis. The complications previously reported in the literature are mostly paradoxical adipose hyperplasia (HAP), but there has been a large increase in unreported injuries in recent years, with several complications such as frostbite, frostbite, panniculitis, HAP and hyperchromia post-inflammation. Objective: This study aims to describe the authors' experience guiding professionals in the management and treatment of several cases of complications resulting from the application of the Cryolipolysis technique. We guided more than 10,000 complications in 12 years, and made a brief review of the world literature on the subject. Materials and Methods: An exploratory study was conducted, presented in a narrative review, to demonstrate the action of the Cryolipolysis technique used in the treatment of aesthetic dysfunctions. The review explored scientific articles published and available in the following databases: MEDLINE (Medical Literature Analysis and Retrieval System Online), PubMed (National Library of Medicine), SCIELO (Scientific Electronic Library Online), LILACS (Latin American and Caribbean Literature in Health Sciences), and Google Scholar. In addition, a series of cases of complications from the use of the cryolipolysis technique that occurred in a multicentric manner and developed with the use of various commercially available equipment were added to this study. Results: when using techniques based on scientific studies, respecting time and temperature, in addition to associations with equipment, drugs and techniques that inhibit cellular precursor factors, we will reduce possible intercurrences and complications. The most common complications described in this study are neuropathic lesions in sympathetic innervation, paradoxical adipose hyperplasia, frostbite, frostnip and hemosiderin hyperpigmentation. Conclusion: The scientific literature demonstrating the lesions and their possible causes with the cryolipolysis technique is robust, but it did not prevent serious complications secondary to the use of Cryolipolysis, which has become common in aesthetics in Brazil and worldwide. Therefore, it deserves full attention for the adoption of appropriate application techniques to minimize such complications, among them: greater temperature control with machines that show the skin temperature on the panel, correct time control, without exaggeration, highquality antifreeze membrane and mandatory use of the “liner” (plastic) as occurs throughout the world, protection of sympathetic innervation through microcurrent and completion of the techniques with inhibition of factors that lead to cell multiplication such as PPAR gamma and CD 68 through shock waves or 40 kHz ultrasound, in addition to not performing vigorous massage on hard frozen tissue.
