Negative pressure device-assisted autologous fat grafting: A case report

Abstract

This report describes a novel technique for improving depressed scars using negative pressure suction-assisted autologous fat grafting. A 35-year-old woman presented with a 20-year history of bilateral central buttock concavities, causing aesthetic concerns. To maximize fat graft survival and enhance tissue volume, we implemented intermittent negative pressure suction on the recipient area for one month preoperatively. The patient expressed satisfaction with the cosmetic outcome, and a three-month follow-up confirmed a significantly improved fat graft survival rate. This minimally invasive, cost-effective, and easily reproducible technique offers a promising clinical strategy for treating depressed scars.
