In dermatology, facial fillers are of great importance in the treatment of wrinkles and expression lines, their use being for aesthetic purposes. Their application is usually carried out with needles, which can lead to complications during the procedure. Among them hematomas, ischemia, necrosis, and even blindness. In recent years however, the application of fillers with microcannulas has revolutionized the techniques of application, in this way avoiding the occurrence of complications during and after the procedure. The present paper is aimed at clarifying the nomenclature, characteristics, and dimensions of the cannulas.

Introdução: A non-invasive alternative for the treatment of localized fat is cryolipolysis that, by freezing adipocytes, reduces fat volume in the region where the procedure was performed. Objective: To statistically describe the experience of a referral center for this procedure. Methods: A cross-sectional study with 251 patients undergoing cryolipolysis was carried out with the epidemiological analysis of patient data. Results: Thirty-eight males and 213 females underwent the procedure, with a total number of 740 treated areas. The anterior abdomen (lower third) was the most popular region, with 45.30% of cases. Eighty-eight percent were satisfied or very satisfied with the result. Nearly all cases required 2 or more sessions to achieve this degree of satisfaction. Conclusions: Cryolipolysis is a noninvasive method for the selective reduction of fat that has shown efficacy in reducing the subcutaneous tissue, with minimal and reversible side effects in this study.
