Background: Mastopexy and reduction mammaplasty are often limited by the patient's poor native soft tissue quality, resulting in ptosis recurrence and loss of rejuvenated surgical results. Surgical scaffolds and acellular dermal matrices are used in these procedures to provide physical and mechanical stabilization of weakened or compromised tissue. GalaFLEX scaffold, made from poly-4-hydroxybutyrate (P4HB), is a next-generation product for soft tissue reinforcement that resorbs gradually while aiding tissue regeneration to achieve excellent outcomes. Objectives: To assess the clinical performance of GalaFLEX scaffold in soft tissue reinforcement during elective mastopexy and reduction mammaplasty. Methods: This multicenter, single-arm, observational study assessed product performance and outcomes of GalaFLEX scaffold when used in breast surgery. Outcomes included ptosis correction and maintenance, associated adverse events, patient and surgeon satisfaction, and mammographic and ultrasound imaging evaluation. Results: At 6 centers in the US, 62 of 69 enrolled patients were treated. Of this population, 89.7% had successful ptosis correction and maintenance at 1 year, with high patient and surgeon satisfaction for breast shape, droop/sag of the breast, and maintenance of results at 1 year. There were 5 adverse events deemed related to the device (8.0%), including nerve pain, breast swelling, ptosis, and 2 instances of asymmetry. Conclusions: GalaFLEX scaffold safely and successfully supports and elevates breast tissue in mastopexy and reduction mammaplasty, with maintained support at 1 year. Surgeon and patient satisfaction were high. No mammogram or ultrasound interference was detected.
