Abstract

From 1978 through 1990, 27 patients with well-differetiated carcinoma of the thyroid gland invading the trachea, larynx or cervical esophagus were treated surgically. Three patients were Ml cases. The mean age of these were 62.3 years old. Twenty-three patients underwent partial resection of the cervical trachea with or without partial laryngectomy. Other 4 patients underwent cervical esophagectomy, subtotal-laryngectomy, total laryngectomy, pharyngo-laryngo-esophagectomy, respectively. Secondary recostruction of the trachea were performed with skin flaps in 16 patients. Five patients were died of distant metastasis and 4 patients were alive with disease. A case of advanced thyroid cancer with invasion of the hypohparynx were reported and conservative surgical procedures were discussed.
