Chest wall reconstruction following extensive resection due to advanced breast cancer or radionecrosis still represents a challenge for both oncologic and reconstructive surgeons. A multitude of techniques including pedicle muscle transposition, free muscle flaps and omental flaps have always been considered, despite the morbidity of donor site.

No major complications occurred. This technique proved to be a very good options to cover large chest wall defects in patients with advanced or recurred breast cancer or radionecrosis.
