Extract
The treatment of cellulite remains an interesting challenge with a huge potential market for anything that actually works. Probably the most significant advancement in the treatment of dimpled cellulite has been tissue stabilized-guided subcision (TS-GS), marketed as Cellfina by Merz North America. Cellfina is described as the first long-lasting, minimally invasive device for improving the appearance of cellulite in a single treatment by addressing the primary structural cause of cellulite. Cellfina has been commercially available for several years and has very good data that, until now, have been entirely contained in the dermatology literature.1-4 This Canadian retrospective cohort study by 2 groups of plastic surgeons is a nice addition to what we know about how this device works in a plastic surgery practice.5 The authors were familiar with the Cellfina Pivotal Study but sought to validate their own shorter-term experience by examining the effectiveness of TS-GS and the level of physician and patient satisfaction associated with the procedure. The authors performed a retrospective chart review and generated data for 25 of the 30 total patients they treated, with the exclusion of 5 patients for valid reasons and some missing data from 2 of the 25 charts that did not affect validity. The authors performed a single Cellfina treatment on all patients and concluded that these patients overwhelmingly (78.3%) had a single point change in the Nürnberger-Müller scale, and the remainder had a 2- or 3-point improvement. Patient and evaluator satisfaction were measured with the GAIS, finding a high rate of patient and evaluator satisfaction with a respectably low complication rate.5
