Collagenase Clostridium Histolyticum-aaes Injections for Volumetric Change of Cellulite Dimples and Gluteal Contouring

Background: Collagenase clostridium histolyticum-aaes (CCH) is approved for the treatment of moderate-to-severe cellulite.

Objective: This is a retrospective image review of subjects previously enrolled in Cohort 2 of the EN3835-305 trial to determine the effects of CCH on volumetric changes of cellulite dimples and overall gluteal contouring.

Methods: In this retrospective analysis, photographs from Day 90 and Day 180 were superimposed on baseline images and the volumetric change of each treated cellulite dimple was quantified. Side-by-side photographs of the buttocks were also evaluated for change in gluteal contour using the Physician Global Aesthetic Improvement Scale (PGAIS).

Results: Fifty-eight female subjects and 403 cellulite dimples were evaluated. Three-dimensional imaging analysis revealed a significant improvement in total negative dimple volume at both Day 90 and Day 180 of 27% and 26%, respectively ( p < .001 and p = .002, respectively). At Day 90, the overall gluteal contour, as signified by the mean PGAIS among the 3 blinded dermatologists, was rated as +1 (improved) in 27% ( n = 17) of the subjects. At Day 180, the mean PGAIS was +1 (improved) or +2 (very much improved) in 39% ( n = 26) of the subjects.

Conclusion: CHH is an effective tool for treating cellulite dimples and improving gluteal contour.
