The Reconstruction of the Donor Site of DP Flap Using Thoracodorsal Artery Perforator Flap

Summary: We performed a new procedure for reconstruction of donor site of a deltopectoral (DP) flap. A 58-year-old man presented with a wide subcutaneous abscess, which was caused by acute mandibular osteomyelitis due to dental caries. On admission, the patient received a neck incision for drainage. However, necrosis of the neck skin was observed after drainage. The patient had an 8 × 10 cm skin and soft-tissue defect, which we covered with a DP flap (15 × 7 cm). The DP flap donor site was reconstructed using a 16 × 8 cm pedicled thoracodorsal artery perforator (TDAP) flap. There was no flap necrosis, abscess formation, or scar contracture of the DP region. Debulking of the TDAP flap was not required. The pedicled TDAP flap is useful for the reconstruction of the donor site of DP flap. In this report, we describe our operative procedure.
