Superficial Circumflex Iliac Artery Perforator Flap Reconstruction for Extensive Skin Defects after Mastectomy

Reconstruction of extensive chest wall skin defects following mastectomy remains challenging, and a variety of reconstructive options have been reported. Although skin grafts, local flaps, and pedicled musculocutaneous flaps are widely used, these approaches may result in suboptimal cosmetic or functional outcomes, carry a relatively high risk of partial flap necrosis, and require sacrifice of muscle tissue. Additionally, achieving stable wound closure without delaying the initiation of postoperative radiotherapy or chemotherapy is particularly important in such cases. Here, we report five patients who underwent immediate reconstruction with a free superficial circumflex iliac artery perforator flap for extensive postmastectomy skin defects. Complete flap survival and timely wound healing were achieved in all cases. Postoperative radiotherapy and chemotherapy were initiated as scheduled in every patient. During the follow-up period, no cases of local recurrence or significant functional impairment were observed. Free superficial circumflex iliac artery perforator flap reconstruction provides reliable coverage for extensive postmastectomy skin defects with minimal donor-site morbidity, enabling early wound healing while preserving the option of future autologous breast reconstruction. The approach represents a valuable addition to reconstructive strategies for breast cancer patients.
