Abstract
Objectives:
The objective of this study was to evaluate the effect of autologous fat grafting in patients with juvenile localized scleroderma with facial involvement.
Methods:
We retrospectively studied patients with juvenile localized scleroderma who were followed at the Hamburg Center for Pediatric and Adolescent Rheumatology at least 6 months post-operative follow-up and received at least one autologous fat transplantation for a facial lesion. Autologous fat grafting was conducted independent of disease-modifying treatment and/or disease activity. The effectiveness of the intervention was evaluated by assessing the immediate volume enhancement after injection of fat tissue compared with volume retained after 6 months. The volume enhancement was calculated from three-dimensional photo images analyzed in Mirror Medical Imaging Software, Canfield Scientific (New Jersey, USA).
Results:
Data of 22 juvenile patients were assessed from March 2006 to September 2021. In six patients, the photos could not be evaluated for the study. The median age of the remaining 16 patients at the beginning of the first fat graft was 8 years (range = 2.5–22 years). Patients underwent mean three interventions (range = 1–9). Evaluation of three-dimensional images showed that the volume retention at 6 months post autologous fat grafting is approximately 50%. The Modified Localized Scleroderma Skin Severity Index value did not correlate to volume changes at 6 months. In 4 of 16 patients, a decrease of the Localized Scleroderma Damage Index occurred. In all seven patients with cheek involvement, mean tragus-nose distance difference decreased (mean decrease 1.09 cm). We did not observe any significant clinical side effects.
Conclusion:
In this first bigger pediatric case series, the mean facial lesion volume increased around 50% after a mean of three interventions at 25 months of follow-up. No flares of the underlying disease were noted. Autologous fat grafting is a promising method to improve the cosmetic appearance of those patients.
