The wall of cervical trachea is often invaded by thyoid cancer. Out of total 65 patients with thyroid cancer in our clinics, 20 showed tracheal invasions, which were resected together with thyroid cancer.After resection of the total circumference in 4 patients, end-to-end anastomosis were carried out by the suprahyoid laryngeal release technique, or after window resection in 9 of 15 patients the surgical defects were reconstructed by free transplantation with cartilage-murosa composite graft of nasal septum. In the remaining 3 of window resections the tracheal stomas were closed only by skin closure without any reconstruction of trachea because the defects were small, and in another 3 the deffects were used for tracheal breathing because of total laryngectomy or incomplete removal of cancer of undifferentiated type.In conclusion, we successfully reconstructed surgical defect of trachea using end-to-end anastomosis or transplantation with composite graft of nasal septum. Anaplastic cancer, however, were not indicated due to poor prognosis.
