Abstract
Introduction: Progressive hemifacial atrophy (PHA) and linear scleroderma (LS) are both rare conditions and defined by atrophy and/or sclerosis of the skin and subcutaneous tissue. The ideal timing of reconstructive intervention in these patients is controversial. We compared the outcome and satisfaction of autologous lipofilling performed during active and stable phases of the diseases in adults. Methods: A retrospective chart review was conducted with all patients diagnosed with PHA or LS between 2007 and 2019 in our department. We analysed demographic data, clinical features, and surgical procedures. The changes in symmetry, volume and skin texture were rated by surgeons at 1 week, 3 months and 6 months compared to the preoperative presentation. We compared the outcomes of patients treated during the active and the stable phase of the disease. Additionally, patients were asked to fill out a quality-of-life questionnaire. Results: We found a total of 11 patients diagnosed with PHA and LS, 8 of whom had undergone autologous fat injections to correct facial asymmetry. Of those, 4 patients were treated in their active and 4 in their stable phase. We found similar treatment outcomes in both groups. The social component had the greatest negative effect on patient's quality of life. Conclusion: In this small cohort, autologous fat grafting during the active phase did not appear to be inferior to fat grafting during the stable phase. It could be a safe technique for correction of PHA and LS during the active phase of disease.
