The lymphatic network including the lymphatic vessels and the lymph nodes can be traumatized during harvest of a perforator\u2010based abdominal flap, eventually causing seroma formation. The aim of this study was to compare postoperative seroma occurrence rates between the deep system group including the deep inferior epigastric artery perforator (DIEP) flap and the superficial system group comprised of the superficial inferior epigastric artery (SIEA) flap, the superficial circumflex iliac artery perforator (SCIP) flap, and the SIEA\u2010SCIP combined flap.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and methods<\/jats:title><jats:p>A retrospective analysis of all patients who underwent unilateral breast reconstruction using perforator\u2010based abdominal flaps from June 2020 to May 2021 was performed. The patients were divided into the deep system group and the superficial system group. Propensity score matching was used to compare in the two groups the mean duration of drainage in the donor site and the occurrence of postoperative aspiration.
