Tissue Expansion After Inverted-T Mammaplasty: Can It Be Performed Successfully?

Breast cancer patients will occasionally need to undergo mastectomy after previous reduction mammaplasty or mastopexy. The presence of the “inverted-T” scar presents a unique reconstructive dilemma: Do mastectomy flaps that are traversed by surgical scars still allow for adequate tissue expansion and a good aesthetic result? The objective of this study was to evaluate the authors’ experience with tissue expansion/implant reconstruction in patients with an inverted-T scar. All patients who underwent tissue expansion and implant reconstruction after inverted-T mammaplasty were reviewed retrospectively to determine aesthetic results, patient satisfaction, and complication rates associated with this reconstructive technique. During a 6-year period (1995–2001), 11 patients (12 breasts) underwent breast reconstruction with tissue expansion and implant placement after either reduction mammaplasty (N = 8) or mastopexy (N = 4). All patients reached target expansion volumes. After successful tissue expansion, exchange to either saline (N = 7) or silicone (N = 5) implants was performed. The mean follow-up period after implant exchange was 18.5 months (range, 2–72 months). Complications were minimal and included partial flap necrosis (N = 1). Aesthetic appearance and symmetry were judged to be good or excellent in the majority of patients. Overall patient satisfaction was high. Tissue expansion with implant exchange is an effective reconstructive technique for mastectomy defects after previous inverted-T mammaplasty. In this series, good to excellent aesthetic results were achieved in the majority of patients with minimal associated complications.
