In contrast to cosmetic abdominoplasty, abdominal flap harvest can result a high degree of morbidity to the abdominal wall. Poor abdominal wall aesthetics that can result following free flap harvest including a high abdominal incision and post-operative hernia or bulge. We report our experience in optimizing cosmesis of the abdominal donor site with the use of a low incision, fascial plication and routine mesh reinforcement. Methods: A retrospective chart review of patients who underwent breast

... reconstruction with free abdominal tissue transfer from 2013-2017. Pedicled flaps and superior inferior epigastric artery flaps were excluded. Patient demographics, oncologic history, ablative and reconstructive surgery details focusing on abdominal closure techniques, and postoperative complications were evaluated. Results: 135 patients were identified who underwent 223 abdominal free flaps. 59 (26.5%) DIEP flaps were harvested, while 160 (71.7%) msTRAM and 4 (1.8%) fTRAM flaps were harvested (p<0.0001). 160 (71.7%) donor sites closures utilized polypropylene mesh, 9 (4.0%) were closed with biologic mesh and 3 (1.3%) closures used no mesh (p<0.0001). No hernias were observed (0%), while 6 abdominal bulges were identified (2.7%). There were no differences in the rates of abdominal bulge after donor site closure in the DIEP compared with msTRAM and fTRAM groups (3.4% vs 2.4%, p=0.7). No patients required mesh explantation during the study follow up period. Conclusion: To parallel cosmetic abdominoplasty, our authors advocate for a low incision, fascial plication and routine mesh reinforcement of the abdominal wall following free flap harvest.
