Lateral Intercostal Artery Perforator (LICAP) Flap for Level II Oncoplastic Breast Reconstruction: Our Initial Experience

<b>Background:</b> Breast-conserving surgery (BCS) combined with radiotherapy achieves oncologic outcomes comparable to mastectomy while preserving breast integrity. However, resections of more than 20% of breast volume or those in challenging quadrants may compromise cosmetic results. Level II oncoplastic techniques using volume replacement flaps aim to address this. The lateral intercostal artery perforator (LICAP) flap is a reliable, muscle-sparing option for lateral and central-lateral breast defects. This study reports our initial experience with LICAP in Level II oncoplastic breast reconstruction. <b>Methods:</b> A retrospective review was conducted of women undergoing BCS with LICAP reconstruction between March 2024 and March 2025. The primary outcome was flap-related complications within 90 days. Secondary outcomes included operative time, hospital stay, donor-site morbidity, and six-month aesthetic results using the Harvard scale and BREAST-Q^® module. <b>Results:</b> Nine women underwent LICAP reconstruction. All tumours were ≤pT2 with negative margins. Mean operative time was 128 min, and the median hospital stay was 2 days. One minor flap-related complication (seroma, 11%) occurred, which was managed conservatively without re-operation or delay in adjuvant therapy. At six months, all patients achieved good or excellent Harvard scores. The mean BREAST-Q^® satisfaction score was 79 ± 12. <b>Conclusions:</b> LICAP reconstruction is safe, efficient, and provides reliable early aesthetic and patient-reported outcomes. Its low complication rate, high satisfaction, and minimal morbidity support its broader adoption, while larger prospective studies are needed to assess long-term results and refine indications. These findings also underline the role of LICAP reconstruction as part of a personalized surgical strategy, where the choice of technique is tailored to individual anatomy and expectations.
