Abstract
BACKGROUND: Cryolipolysis is a minimally invasive technique used to decrease local adipose tissue by thermal cooling. Paradoxical adipose hypertrophy (PAH) is a rare complication of cryolipolysis with important aesthetic consequences. OBJECTIVES: The objective of this study was to describe four cases of PAH after a cryolipolysis treatment. METHODS: Between January 2014 and January 2017, all patients who had undergone a cryolipolysis treatment in a single center were reviewed. The device used was a CoolSculpting device and the same operator performed all the cryolipolysis treatments. We retrospectively included all patients who had a suspicion of PAH. RESULTS: In our study, 398 patients underwent a session of cryolipolysis. Four patients presented with a voluminous painless swelling in the treated area, between 2 and 4 months after the cryolipolysis session. One patient was treated with liposuction. Histological analysis of the adipose tissue in this patient revealed a nonspecific panniculitis. The other three patients did not receive any additional treatment, and their symptoms stabilized after several months. CONCLUSIONS: Although cryolipolysis generally yields good results, it can be complicated with PAH, which tends to occur a few months after the cryolipolysis treatment. Patients should be informed of the possibility of developing this complication and encouraged to attend regular follow up for at least 6 months, so that this condition can be readily detected. Surgical treatment should be offered if there is no spontaneous improvement of the symptoms.
