The application of chimeric deep circumflex iliac artery perforator flap for oromandibular reconstruction: A case report.

Medicine (Baltimore) 2021 Apr;100(14):e25458

Department of Head and Neck Cancer Center.

Rationale: The free fibular flap is considered the gold standard, particularly for a mandibular defect combined with a significant soft tissue defect. However, the fibular flap has the disadvantages of a lack of height for postoperative dental restoration and donor site skin graft if the skin paddle is wider than 5 cm. The larger bone and soft tissue defects tend to be reconstructed using either a scapula or a combination of iliac artery and radial free flap. Read More
