The Ergonomic FALD Flap for One-stage Total Breast Reconstruction

Abstract

Background: The fat-augmented latissimus dorsi (FALD) flap combines this pedicled flap with immediate intraoperative fat transfer. Very little is described concerning its inset at the mammary site. Our efforts have concentrated on seeking the best flap orientation and skin-adipose paddle shaping, to improve the aesthetic outcome and to obtain a complete breast reconstruction (BR) in one stage. Methods: A prospective clinical study was performed in patients who underwent BR with FALD flaps, between December 2020 and March 2022. Patients were randomly enrolled into two groups: ergonomic inset of the FALD flap with vertical orientation of the skin-adipose paddle (group A) and FALD flap with traditional horizontal paddle orientation (group B). The study’s endpoints were the evaluation of the aesthetic outcomes (from patients’ and surgeon’s perspectives) and complications. Results: Thirty-two FALD flaps (23 patients) were performed for group A, and 31 FALD flaps (25 patients) for group B. The two groups were homogeneous in terms of demographic and surgical data ( P > 0.05). The overall complication rate was homogeneous among the groups, without statistically significant differences ( P = 1.00). The surgeon’s assessments showed a statistically significant superior aesthetic outcome in group A regarding volume, symmetry, and shape ( P < 0.05). Higher satisfaction was observed in group A patients, in terms of breast size ( P < 0.00001), shape ( P = 0.0049), and overall satisfaction ( P = 0.00061). Conclusions: The ergonomic vertical FALD flap technique enables surgeons to perform one-stage total BR, with excellent breast projection and upper pole fullness. These refinements in flap shaping and molding reduced the need for further autologous fat transfer, obtaining a brilliant totally autologous BR without the need for microsurgical experience.
