Reliability of Chest Wall Perforator Flaps for Breast Reshaping following Massive Weight Loss

Breast deformity following massive weight loss poses a unique challenge inadequately managed by traditional methods. Patients also have considerable lateral and posterior upper trunk tissue surplus. Multiple studies have used chest wall flaps for auto-augmentation with mastopexy to tackle this problem. However, the outcome measures did not include any objective tools to assess the reliability of these flaps. Hence, in this study sono-mammography and breast anthropometric measurements are used for evaluation of the added volume and long-term sustainability of chest wall perforator flaps.

Twenty massive weight loss patients with Pittsburgh Rating Scale score 2-3 underwent mastopexy with autologous augmentation through perforator flaps encompassing lateral chest wall skin. Outcome measures were breast volume, and the presence of fat necrosis on mammography, and direct breast anthropometry.

All patients showed a consistent increase in volume postoperatively and no fat necrosis in postoperative mammography, reflecting flap reliability over one year of follow-up. All postoperative anthropometric measurements showed improvement in the breast deformities addressed.
