Abstract

This study explored an effective method for repairing cranio-maxillofacial soft-tissue defects following radical craniofacial surgery in four patients with malignant tumours involving the skull base and frontal region. The large cranio-maxillofacial soft-tissue defects were reconstructed using an extended vertical lower trapezius island myocutaneous flap based on the transverse cervical artery. The flap was 8–12 cm long and 5–7 cm wide. No major flap failure occurred, and there was no shoulder dysfunction. The patients were followed for 3–12 months. One patient suffered a local recurrence, and another died of lung metastasis 12 months postoperatively. The extended vertical lower trapezius island myocutaneous flap is a simple, reliable and large flap. It is preferred for reconstructing cranio-maxillofacial soft-tissue defects when a pedicled flap is used following craniofacial surgery for cancer.
