Safe reconstruction of a large cervico-mediastinal tracheal defect with a pectoralis major myocutaneous flap and free costal cartilage grafts.
A large cervico-mediastinal tracheal defect in a 72-year-old man as a result of surgery for thyroid carcinoma with tracheal invasion and mediastinal lymph node metastasis was reconstructed using a pectoralis major myocutaneous flap and free costal cartilage grafts. The tracheal defect (55 mm x 30 mm) was located at the thoracic inlet adjacent to the major mediastinal vessels. Our reconstructive procedure was a two-staged surgery. In the first stage, a pectoralis major myocutaneous flap was transferred to the neck to provide a well-vascularized recipient bed for free costal cartilage grafts and to cover large vessels. Two pieces of free costal cartilage were grafted on the pectoralis major myocutaneous flap, one for the lateral wall reconstruction and the other prefabricated for the anterior wall of the trachea. In the second stage, the re-vascularized cartilage graft for the anterior wall of the trachea with overlying skin was rotated onto the trough of the remaining trachea and the closure of the tracheal defect was completed. We conclude that free cartilage grafts for the reconstruction of a large cervico-mediastinal tracheal defect can be safely used when they are combined with well-vascularized pectoralis major myocutaneous flaps.
