Fat removal using a new cryolipolysis device: a retrospective study of 418 procedures.

Editor The selective effect of cold on the hypodermis is a well-known medical phenomenon. Cryolipolysis induces selective apoptosis of the adipocytes using controlled exposure to intense cold. Its safety and efficacy has been reported in several studies but was recently challenged. A retrospective, observational, monocentric post-marketing study was conducted. A single session of cryolipolysis was evaluated on subjects who consulted for fat removal. Subjects were included consecutively and paid for their treatment. Patients with medical history of cold disorders such as cryoglobulin or Raynaud’s disease, visceral hernias, pregnancy, caesarean section within the last 6 months were excluded. The device used [Cristal cryolipolysis (Deleo, Saint Raphael, France)] benefits from the medical CE marking. It has two slightly curved handpieces that can be used simultaneously, with three different sizes. Thick protective epidermal membrane soaked with a cold-resistant gel was applied on the area. Cooling temperature was between 6 °C and 10 °C. Treatment duration was 60 min per area. A 5-min energetic massage was carried out immediately after treatment. A topical cream containing arnica extract (Cicabio Arnica+ , Laboratoire Bioderma, Lyon, France) which reduces bruising was prescribed in order to limit and treat secondary ecchymosis caused by suction. A total of 418 areas in 147 subjects underwent the procedure. Areas were: abdomen (144), anterolateral flank (156), inner thighs (48), back (26), underside of buttocks (26), inner knees
