Three-dimensional reconstruction of hip and groin region by division and rotation of skin paddle using oblique rectus abdominis musculocutaneous flap after squamous cell carcinoma resection

Abstract

Reconstructing extensive defects in the hip and groin region is challenging. Although the technique of wrapping the flaps is often chosen, achieving effective coverage of defects is difficult because of the tissue bulge in the center, and a skin graft is frequently required. We herein report a case of successful hip “corner” reconstruction using a pedicled oblique rectus abdominis musculocutaneous flap with division and rotation of the skin paddles after squamous cell carcinoma resection. The patient had a history of immunosuppressive treatment, radiation therapy, and surgeries on the ipsilateral thigh. Our technique minimized the sacrifice of the flap donor site, achieved primary closure, and resulted in a favorably shaped reconstruction with respect to three-dimensional morphology. The patient's postoperative quality of life was ultimately improved.
