Abstract
BACKGROUND: Oncoplastic breast conservation has been classically divided into volume displacement (VD) or volume replacement (VR) techniques. There have been few descriptions of merging these two approaches. This report describes our experience combining Wise-pattern VD and autologous VR to repair extensive partial mastectomy defects in patients with ptosis. METHODS: A retrospective chart review was performed for patients who underwent combined Wise-pattern VD surgery and autologous VR by the author from June 2017 to June 2023, with at least 6 months follow-up. Patient demographics, oncological and intraoperative details, and complications were recorded. RESULTS: Forty patients underwent Wise-pattern VD surgery combined with a medial intercostal artery perforator flap (five patients), lateral thoracic artery perforator/lateral intercostal artery perforator flap (18 patients), anterior intercostal artery perforator flap (five patients), or muscle-sparing latissimus dorsi flap (12 patients). The average tumor size was 4.0 cm (range, 1.5-9.1 cm), and specimen weight was 152 g (range, 33-415 g). Six patients (15%) required re-operation for positive margins. There was delayed healing of three (7.5%) donor sites. There were no flap failures. Two (5%) patients had clinically apparent fat necrosis without requirement for surgical revision. CONCLUSIONS: This report demonstrates the feasibility of combining Wise-pattern VD and autologous VR. We propose that oncoplastic breast-conserving surgery be no longer divided into two mutually exclusive approaches and that surgeons make liberal use of combining these approaches to address challenging cases of breast-conserving surgery.
