Differentiated thyroid carcinoma is not highly malignant, and thus surgical resection is the most common treatment even if the carcinoma has invaded the trachea. Although some cases exist in which the carcinoma invades the trachea, using the tracheal window resection method allows complete resection of the carcinoma. Yet these patients must often control a large tracheocutaneous wound until reconstructive surgery is performed because such surgery occurs secondarily. Our hospital admitted three patients for which tracheally invasive, differentiated thyroid carcinoma was surgically resected. Tracheal defects of 1/2 to 2/3 of the tracheal circumference were reconstructed primarily using the free forearm flap and costal cartilage during carcinoma resection. Following surgery, only a small tracheocutaneous fistula remained open, which was closed at about three months post-operation. The reconstructed tracheal space and transferred costal cartilage thickness were monitored by CT scan imaging at about 12 months post-operation. Details of the reconstructive method and postoperative changes in the reconstructed trachea and thickness of the costal cartilage are described in this report.
